• Inconsistent table width when hideing/showing a set of columns

  - by Salman A. Kagzi

  I have got a an HTML table of around 40+ columns. To make this table fit in the screen and have the data in a re presentable format we have section in this table. i.e. there are some column that are always visible and the remainder a made visible when s specific radio button (describing a section) is selected. Each radio button is associated to different number of columns. We show/hide a column by setting/removing "display:none" style in all the cell under that column. This all works Just fine. Now the real problem is with the width of the columns in this table. I cant use fixed with with pixel settings. I have tried using the percentage setting by giving 50% to the always visible part and rest 50% is divided between the column in a section. But I am unable to get a fixed behavior i.e. the size of the table columns across IE & FF. Some columns are just right while some are really huge. How can I get the table to give consistent column width across browsers?

• ASP .NET Added Event Handlers to buttons on Page_Load. Event handlers do not fire the first click, b

  - by John

  Background: I am customizing an existing ASP .NET / C# application. It has it's own little "framework" and conventions for developers to follow when extending/customizing its functionality. I am currently extending some of it's administrative functionality, to which the framework provides a contract to enforce implementation of the GetAdministrationInterface() method, which returns System.Web.UI.Control. This method is called during the Page_Load() method of the page hosting the GUI interface. Problem: I have three buttons in my GUI, each of which have been assigned an Event Handler. My administration GUI loads up perfectly fine, but clicking any of the buttons doesn't do what I expect them to do. However, when I click them a second time, the buttons work. I placed breakpoints at the the beginning of each event handler method and stepped through my code. On the first click, none of the event handlers are triggered. On the second click, they are triggered. Any ideas? Example of Button Definition Button btn = new Button(); btn.Text = "Click Me Locked Screen"; bth.Click += new EventHandler(Btn_Click); Example of Event Handler Method Definition void Btn_Click(object sender, EventArgs e) { // Do Something }

• View transform seems to be ignored when animating on iphone. Why?

  - by heymon

  I have views that can be rotated, scaled and moved around the screen. I want the view to resize and be orthogonal when the user double tap's the view to edit the textview within. The code is below. Somewhere the transform is getting reset. The NSLog statement below prints the identity transform, but a print of the transform when the animation is complete in transitionDidStop reveals that the transform is what it was before I thought I set it to identity. The view resizes, but it acts like the transform was never set to identity? Any ideas/pointers? originalBounds = self.bounds; originalCenter = self.center; originalTransform = self.transform; r = CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width - 70, 450); [UIView beginAnimations: nil context: NULL]; [UIView setAnimationDelegate: self]; [UIView setAnimationDidStopSelector: @selector(transitionDidStop:finished:context:)]; self.transform = CGAffineTransformIdentity; NSLog(@"%@ after set", NSStringFromCGAffineTransform([self transform])); [self setBounds: r]; [self setCenter: p]; [self setAlpha: 1.0]; [UIView commitAnimations]; [textView becomeFirstResponder];

• Moving UIScrollView in App

  - by jsetting32

  Currently, I am attempting to create the same effect as Yahoo! Weather's App where the vital day information is at the bottom of the page on the top of a UIScrollView, that's contained by a UIView. I am having a hard time thinking about how this is going to happen or how I should implement this. If the user taps on the top of the UIScrollView which is located near the bottom of the laoded UIView, and starts to scroll up (/), the UIScrollView's frame should be moved to the TOP of the current UIView's frame. So the UIScrollView's y-value should change to UIView's (self.view.frame.origin.y) if the user starts scrolling UP on the UIScrollView which is located on the UIView's y-pixel ~280. Here's what the UIViewController should look like in the beginning of loading the ViewController... Then once the user slides his finger from the bottom to the top of the screen... this should happen........ And when the user scrolls to the top of the UIScrollView with all the content within it... the view should go back to the start picture shown... How is this done? I was thinking several UIGestureRecognizer's and Instantiating the UIscrollview at the lower part of the UIView... _weatherView = [[UIScrollView alloc] initWithFrame:CGRectMake(self.view.frame.origin.x, self.view.frame.origin.y + 250, self.view.bounds.size.width, self.view.bounds.size.height - 44)]; _weatherView.contentSize = CGSizeMake(self.view.bounds.size.width, self.view.bounds.size.height * 4); _weatherView.backgroundColor = [UIColor clearColor]; [self.view addSubview:_weatherView]; The adding some UIGestureRecognizer delegate method.... But anyone have any ideas on the UIGestureRecognizer delegate method? And how it should be implemented? I can write the psuedo-code but I am having problems finding the delegate methods :P Thank you!!! ---- Break Time.... :)

• Application design question, best approach?

  - by Jamie Keeling

  Hello, I am in the process of designing an application that will allow you to find pictures (screen shots) made from certain programs. I will provide the locations of a few of the program in the application itself to get the user started. I was wondering how I should go about adding new locations as the time goes on, my first thought was simply hard coding it into the application but this will mean the user has to reinstall it to make the changes take affect. My second idea was to use an XML file to contain all the locations as well as other data, such as the name of the application. This also means the user can add their own locations if they wish as well as sharing them over the internet. The second option seemed the best approach but then I had to think how would it be managed on the users computer. Ideally I'd like just a single .exe without the reliance on any external files such as the XML but this would bring me back to point one. Would it be best to simply use the ClickOnce deployment to create an entry in the start menu and create a folder containing the .exe and the file names? Thanks for the feedback, I don't want to start implementing the application until the design is nailed.

• How to obtain the panel within a treeview (WPF)

  - by sperling

  How can one obtain the panel that is used within a TreeView? I've read that by default TreeView uses a VirtualizingStackPanel for this. When I look at a TreeView template, all I see is <ItemsPresenter />, which seems to hide the details of what panel is used. Possible solutions: 1) On the treeview instance ("tv"), from code, do this: tv.ItemsPanel. The problem is, this does not return a panel, but an ItemsPanelTemplate ("gets or sets the template that defines the panel that controls the layout of the items"). 2) Make a TreeView template that explicitly replaces <ItemsPresenter /> with your own ItemsControl.ItemsPanel. I am providing a special template anyways, so this is fine in my scenario. Then give a part name to the panel that you place within that template, and from code you can obtain that part (i.e. the panel). The problem with this? see below. (I am using a control named VirtualTreeView which is derived from TreeView, as is seen below): , use following: -- [sorry folks about poor formatting here, this is my first post, I tried 4 spaces for code... doesn't seem to work?] [I stripped out all clutter here for visibility...] The problem with this is: this immediately overrides any TreeView layout mechanism. Actually, you just get a blank screen, even when you have TreeViewItems filling the tree. Well, the reason I want to get a hold of the panel is to take some part in the MeaureOverride, but without going into all of that, I certainly do not want to rewrite the book of how to layout a treeview. I.e., doing this the step #2 way seems to invalidate the point of even using a TreeView in the first place. Sorry if there is some confusion here, thanks for any help you can offer.

• JSF: Showing/Calling a dialog programatically

  - by Sway

  has anybody an idea to show/call a dialog programatically and add this to stage(actual browser window) ?! I am running in circles and cannot find a solution :/ More background what I want to do: I want to trigger a database update every 2 hours. This I have done with a TimerTask... This works fine for me, the Timertask gets all the data I want from the database... Before this TimerTask is triggered I want to "lock" the screen for some seconds that no user(session scoped) can access the database(this I also know how this will work) ... My problem is that I don't know/ cannot find a way/ i am to stupid to call a dialog programatically ... Any tips, hints would be very cool :) Thanks a lot ! UPDATE: I want to set this primefaces dialog: Dialog dialog = new Dialog(); dialog.setAppendToBody(true); dialog.setModal(true); dialog.setVisible(true); dialog.setWidgetVar("generatedDialog"); dialog.setId("fancyDialog"); dialog.setClosable(false); dialog.setHeader("Getting latest information from the database"); dialog.setDynamic(true); dialog.setResizable(false); dialog.setDraggable(false); How can I do that ? :/ How do I display it to my browser ? :o Regards

• Is there a way to touch-enable scrolling in a WPF ScrollViewer?

  - by Brian Sullivan

  I'm trying to create a form in a WPF application that will allow the user to use iPhone-like gestures to scroll through the available fields. So, I've put all my form controls inside a StackPanel inside a ScrollViewer, and the scrollbar shows up as expected when there are too many elements to be shown on the screen. However, when I try to test this on my touch-enabled device, a panning gesture (placing a finger down on the surface and dragging it upward) does not move the viewable area down as I would expect. When I simply put a number of elements inside a ListView, the touch gestures work just fine. Is there any way to enable the same kind of behavior in a ScrollViewer? My window is structured like this: <Window x:Class="TestTouchScrolling.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525" Loaded="Window_Loaded"> <Grid> <ScrollViewer Name="viewer" VerticalScrollBarVisibility="Auto"> <StackPanel Name="panel"> <StackPanel Orientation="Horizontal"> <Label>Label 1:</Label> <TextBox Name="TextBox1"></TextBox> </StackPanel> <StackPanel Orientation="Horizontal"> <Label>Label 2:</Label> <TextBox Name="TextBox2"></TextBox> </StackPanel> <StackPanel Orientation="Horizontal"> <Label>Label 3:</Label> <TextBox Name="TextBox3"></TextBox> </StackPanel> <!-- Lots more like these --> </StackPanel> </ScrollViewer> </Grid>

• Jquery .Show() .Hide() not working as expected

  - by fizgig07

  I'm trying to use the show and hide to display a different set of select options when a certain report type is selected. I have a couple problems with this: The .show .hide only execute properly if I pass params, slow fast, in the the first result of my conditional statement. If I take out the params or pass params in both results, only one select shows and it never changes.. here's is the code that currently kind of works. if ($('#ReportType').val() == 'PbuseExport') { $('#PbuseServices').show('fast'); $('#ReportServiceDropdown').hide('fast'); } else { $('#PbuseServices').hide(); $('#ReportServiceDropdown').show(); } After i've used this control I am taken to a differnt page. When I use the control again, it reatins the original search values and repopulates the control. Then again I only want to show one select option if a certain report is chosen.. This works correctly if the report type I originally searched on is not the "PbuseExport". If I searched on the report type "PbuseExport", then both selects show on the screen, and only until I change the report type does it show only one select. I know this probably isn't very clear.. Here is the code that handles the change event on the report type drop down. var serviceValue = $("#ReportType").val(); switch (serviceValue) { case 'PbuseExport': $('#PbuseServices').show('fast'); $('#ReportServiceDropdown').hide('fast'); default: $('#PbuseServices').hide(); $('#ReportServiceDropdown').show(); break; }

• Loading an FLV in Facebox with jQuery for IE7 and IE8

  - by Trip

  It goes almost without saying, this works perfectly in Chrome, Firefox, and Safari. IE (any version) being the problem. Objective: I am trying to load JWplayer which loads an FLV from S3 in a Facebox popup. jQuery(document).ready(function($) { $('a[rel*=facebox]').facebox() }) HTML (haml): %li#videoGirl = link_to 'What is HQchannel?', '#player', :rel => 'facebox' .grid_8.omega.alpha#player{:style => 'display: none;'} :javascript var so = new SWFObject('/flash/playerTrans.swf','mpl','640px','360px','0'); so.addParam('allowscriptaccess','always'); so.addParam('allowfullscreen','true'); so.addParam('wmode','transparent'); so.addVariable('file', 'http://hometownquarterlyvideos.s3.amazonaws.com/whatishqchannel.flv&autostart=true&controlbar=none&repeat=always&image=/flash/video_girl/whatishqchannel.jpg&icons=false&screencolor=none&backcolor=FFFFFF&screenalpha=0&overstretch'); so.addVariable('overstretch', 'true') so.write('player'); Problem: Despite the video being set to display: none;. It begins playing anyway. When clicking on the activation div, IE7 pops up a wrong sized blank div with a nav (params are set to not show nav and scrubber), and no buttons on the nav and srubber work. IE8 shows the right size but same behavior with nav and scrubber not working, and blank screen. My guess: I'm thinking that the problem is with the javascript not being called at the right times. It seems it's loading the facebox without the jwplayer. At least I assume. Hence the reason why the nav is there. I thinking that it did not read the javascript for that.

• Vector insert() causes program to crash

  - by wrongusername

  This is the first part of a function I have that's causing my program to crash: vector<Student> sortGPA(vector<Student> student) { vector<Student> sorted; Student test = student[0]; cout << "here\n"; sorted.insert(student.begin(), student[0]); cout << "it failed.\n"; ... It crashes right at the sorted part because I can see "here" on the screen but not "it failed." The following error message comes up: Debug Assertion Failed! (a long path here...) Expression: vector emplace iterator outside range For more information on how your program can cause an assertion failure, see the Visual C++ documentation on asserts. I'm not sure what's causing the problem now, since I have a similar line of code elsewhere student.insert(student.begin() + position(temp, student), temp); that does not crash (where position returns an int and temp is another declaration of a struct Student). What can I do to resolve the problem, and how is the first insert different from the second one?

• Confused about UIView frame property

  - by slowfungus

  I'm building a prototype iPad app that draws diagrams. I have the following view hierarchy: UIView UIScrollView DiagramView : UIView TabBar NavigationBar And a UIViewController subclass holding all that together. Before drawing the diagram the first time I calculate the dimensions of the diagram, and set the DiagramView frame to that size, and the content size of the scrollview as well. -(void)recalculateBounds { [renderer diagram:diagram shouldDraw:NO]; SQXRect diagramRect = SQXMakeRect(0.0,0.0,[diagram bounds].size.width,[diagram bounds].size.height); self.frame = diagramRect; [(UIScrollView*)[self superview] setContentSize:diagramRect.size]; } I should disclose that the frame is being set to about 1500 x 3500 which i know is ridiculous. I just want to focus on some other parts of the app before I get into optimizing the render code. This works beautifully, except that the rect being passed to drawRect is not the size that I set, and my drawing is getting clipped at the bottom. Its close the size i set, but bigger in width, and shorter in height. Also of note, is the fact that if I force the frame to be much bigger than what I know the diagram needs, then the drawRect:rect is big enough, and no clipping occurs. Of course this has me wondering if the frame size needs to take into account some other screen real estate like the toolbars but my reading of the docs tells me the frame is in superview coordinates, which would be the scrollview so I reckon I need to worry about such things. Any idea what is causing this discrepancy?

• [jquery] multiple resizables acting strange

  - by Noweem

  Hi there everyone, I'm trying to place multiple resizable and draggable div's on one page that move (vertically) inside their own parent div. you can take a look at http://bit.ly/bCutBE However, these div's act really strange when I want to resize them, especially from the north side, they kind of move out of the screen very fast, while they shouldn't be able to get outside the parent div. I only want the div to be able to move and resize vertically inside it's parent, the dragging-part works pretty good, but the resize part give this problem. I can't really describe it better than this, but take a look for yourself and it will be clear immediately when you try to resize one of the coloured div's: move it a little downwards and try to resize it from the north side. the problem seems to be caused by the containment: 'parent', line of the resizable. when I delete this line it works fine, but then the coloured blocks don't stay in their parent, and I want them to stay inside their parent. I hope someone can help me with this... the jquery code I used: $(document).ready(function(){ $(".move") .draggable({ containment: 'parent', grid: [50,50], axis: 'y' }) .resizable({ containment: 'parent', grid: [50,50], handles: 'n, s', minHeight: 50 }); });

• How to add images while moving finger across UIView?

  - by Luke Irvin

  I am having issues adding an image across a view while moving finger across the screen. Currently it is adding the image multiple times but squeezing them too close together and not really following my touch. Here is what I am trying: -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch * touch = [touches anyObject]; touchPoint = [touch locationInView:imageView]; if (touchPoint.x > 0 && touchPoint.y > 0) { _aImageView = [[UIImageView alloc] initWithImage:aImage]; _aImageView.multipleTouchEnabled = YES; _aImageView.userInteractionEnabled = YES; [_aImageView setFrame:CGRectMake(touchPoint.x, touchPoint.y, 80.0, 80.0)]; [imageView addSubview:_aImageView]; [_aImageView release]; } } -(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { [self touchesBegan:touches withEvent:event]; } Any suggestions is much appreciated. EDIT: What I want: After taking or choosing an image, the user can then select another image from a list. I want the user to touch and move their finger across the view and the selected image will appear where they drag their finger, without overlapping, in each location.

• UIImageView Fade-In Dissapears

  - by Winder

  I have this code which should create a splash image with either no animation or a fade in, then call code to dismiss the image out after a delay. The SplashViewAnimationNone works fine and creates the full screen image, but the Fade code fades the image in but then immediately disappears. - (void)startSplash { [[[[UIApplication sharedApplication] windows] objectAtIndex:0] addSubview:self]; splashImage = [[UIImageView alloc] initWithImage:self.image]; if (self.animationIn == SplashViewAnimationNone) { [self addSubview:splashImage]; } else if (self.animationIn == SplashViewAnimationFade) { [self addSubview:splashImage]; CABasicAnimation *animSplash = [CABasicAnimation animationWithKeyPath:@"opacity"]; animSplash.duration = self.animationDelay; animSplash.removedOnCompletion = NO; animSplash.fillMode = kCAFillModeForwards; animSplash.fromValue = [NSNumber numberWithFloat:0.0]; animSplash.toValue = [NSNumber numberWithFloat:1.0]; animSplash.delegate = self; [self.layer addAnimation:animSplash forKey:@"animateOpacity"]; } // Dismiss after delay.

• A dynamic array of a class, inside another separate class?

  - by pinnacler

  I'm working on a robot localization simulator and I created a class called "landmark". The end result is going to be a robot that is always centered and always faces the top of the screen. As it turns, the birds eye view map will rotate around the robot. To accomplish this, I'm assuming I can rotate one class and have all elements inside rotate as well. So, the landmark class has properties x,y, label, and radius. This is suppose to simulate a tree location in a forest. To test everything, I need "forest data," and I wrote a script to generate 100 trees in a 100m x 100m area. The script automatically generates values within an acceptable range for x,y, radius. The generated data is stored in an object called tempForest and is 100x3. Ideally, I want to create a class called "landmarks" (plural) that has 100 landmark instances inside. How would I instantiate 100 instances of landmark in one instance of landmarks using that randomly generated data? Ideally, I'd just type treeBeacons = landmarks(); and it would randomly populate 100 (user definable, set in config file) instances with x, y, radius data. I'm not sure how to deal with a dynamic array of class "Landmark", inside another single class "landmarks." Any ideas?

• How do I use InputType=numberDecimal with the "phone" soft keypad?

  - by Adam Dunn

  For an EditText box, the user should only be entering valid numbers, so I am using android:inputType="numberDecimal". Unfortunately, the soft keyboard that Android brings up has numbers only along the top row, while the next three rows have various other symbols (dollar sign, percent sign, exclamation mark, space, etc). Since the numberDecimal only accepts numbers 0-9, negative sign, and decimal point, it would make more sense to use the "phone" soft keyboard (0-9 in a 3x3 grid, plus some other symbols). This would make the buttons larger and easier to hit (since it's a 4x4 grid rather than a 10x4 grid in the same screen area). Unfortunately, using android:inputType="phone" allows non-numeric characters such as parentheses I have attempted to use android:inputType="numberDecimal|phone", but the numberDecimal aspect of the bit flag seems to be ignored. I have also tried using android:inputType="phone" in combination with android:digits="0123456789-.", but that still allows multiple negative signs or decimal points (inputType="number" has really good error checking for things like that, and won't let the user even type it in). I have also tried using android:inputType="phone" in the xml layout file, while using a DigitsKeyListener in the java code, but then that just uses the default number soft keyboard (the one that has numbers only along top row) (it appears to set InputType.TYPE_CLASS_NUMBER, which voids the InputType.TYPE_CLASS_PHONE set by the xml layout). Writing a custom IME wouldn't work, since the user would have to select the IME as a global option outside the app. Is there any way to use the "phone" style soft keyboard while also using the "number" restrictions on what is entered?

• How do I create a hyperlink in java?

  - by Justin984

  I'm going through the google app engine tutorials at https://developers.google.com/appengine/docs/java/gettingstarted/usingusers I'm very new to google app engine, java and web programming in general. So my question is, at the bottom of the page it says to add a link to allow the user to log out. So far I've got this: public void doGet(HttpServletRequest req, HttpServletResponse resp) throws IOException { UserService userService = UserServiceFactory.getUserService(); User user = userService.getCurrentUser(); if(user != null){ resp.setContentType("text/plain"); resp.getWriter().println("Hello, " + user.getNickname()); String logoutLink = String.format("<a href=\"%s\">Click here to log out.</a>", userService.createLogoutURL(req.getRequestURI())); resp.getWriter().println(logoutLink); }else { resp.sendRedirect(userService.createLoginURL(req.getRequestURI())); } } However instead of a link, the full string is printed to the screen including the tags. When I look at the page source, I have no tags or any of the other stuff that goes with a webpage. I guess that makes sense considering I've done nothing to output any of that. Do I just do a bunch of resp.GetWriter().println() statements to output the rest of the webpage, or is there something else I don't know about? Thanks!

• Resize issue to fit dynamically with any browser size

  - by Qpixo

  I'm trying to make full flash site dynamically resize in any browser size. If the browser gets smaller than the site MC should constrain to fit in the browser. (EX: 1440x900) What I have right now works like 98% of the time, but when I switch to a bigger screen size, it screws up and makes the site tiny from left to right (menu, logo, etc.) (Ex:1680x1050) Does anyone know how to fix that issue?? positionScenesOnStage(); stage.align = StageAlign.TOP_LEFT; stage.scaleMode = StageScaleMode.NO_SCALE; stage.addEventListener(Event.RESIZE, handleObjectsOnStage); private function handleObjectsOnStage(event:Event):void { positionScenesOnStage(); } private function positionScenesOnStage():void { backgroundMC = new bgMC(); backgroundMC.x = 0; backgroundMC.y = 0; backgroundMC.width = stage.stageWidth; backgroundMC.height = stage.stageHeight; addChild(backgroundMC); logo_mc = new LogoMC(); logo_mc.x = stage.stageWidth - 1420; logo_mc.y = stage.stageHeight - 700; addChild(logo_mc); menuContainer = new MenuContainerMC(); menuContainer.x = stage.stageWidth - 400; menuContainer.y = stage.stageHeight - 680; addChild(menuContainer); }

• Using pointers to adjust global objects in objective-c

  - by Rob

  Ok, so I am working with two sets of data that are extremely similar, and at the same time, these data sets are both global NSMutableArrays within the object. data_set_one = [[NSMutableArray alloc] init]; data_set_two = [[NSMutableArray alloc] init]; Two new NSMutableArrays are loaded, which need to be added to the old, existing data. These Arrays are also global. xml_dataset_one = [[NSMutableArray alloc] init]; xml_dataset_two = [[NSMutableArray alloc] init]; To reduce code duplication (and because these data sets are so similar) I wrote a void method within the class to handle the data combination process for both Arrays: -(void)constructData:(NSMutableArray *)data fromDownloadArray:(NSMutableArray *)down withMatchSelector:(NSString *)sel_str Now, I have a decent understanding of object oriented programming, so I was thinking that if I were to invoke the method with the global Arrays in the data like so... [self constructData:data_set_one fromDownloadArray:xml_dataset_one withMatchSelector:@"id"]; Then the global NSMutableArrays (data_set_one) would reflect the changes that happen to "array" within the method. Sadly, this is not the case, data_set_one doesn't reflect the changes (ex: new objects within the Array) outside of the method. Here is a code snippet of the problem // data_set_one is empty // xml_dataset_one has a few objects [constructData:(NSMutableArray *)data_set_one fromDownloadArray:(NSMutableArray *)xml_dataset_one withMatchSelector:(NSString *)@"id"]; // data_set_one should now be xml_dataset_one, but when echoed to screen, it appears to remain empty And here is the gist of the code for the method, any help is appreciated. -(void)constructData:(NSMutableArray *)data fromDownloadArray:(NSMutableArray *)down withMatchSelector:(NSString *)sel_str { if ([data count] == 0) { data = down; // set data equal to downloaded data } else if ([down count] == 0) { // download yields no results, do nothing } else { // combine the two arrays here } } This project is not ARC enabled. Thanks for the help guys! Rob

• css layout for footer at bottom with dynamic ajax content changing height of page

  - by m42

  [Update] I actually compromised on this problem for now by foregoing the fixed footer design. It seems that there is no problem with dynamic content moving the footer and resizing containers appropriately unless the footer is fixed to the browser bottom initially. I hope others will eventually provide a great solution that encompasses the best of both worlds. I spent all day trying to get the footer to move down the page to accommodate dynamically added (via ajax) content. I really need some pointers or links because I haven't found anything that helps. Basically: My site has some pages that begin with only a text box and a button so that the total height of the content area is only a few inches beneath the header area. I don't have any problem getting the sticky footer working so that the footer appears at the bottom of the browser window even when there is very little content on screen. That same css layout works fine for other pages that have content that extends beneath the browser window. The catch: The content has to be rendered and passed to the browser with the initial load. The Problem: Any content that is added to the page via AJAX after the initial load paints down the page correctly -- but the footer remains in its initial location. Please tell me there is a fix for this. I can't post the css until checking with my boss first - if possible - and if needed, I will later - but it's just a very basic version of the many sticky footer css solutions floating around the web.

• How can I prevent a page to jump to top position after failed validation?

  - by Slauma

  I have a simple aspx page with a few TextBoxes and a submit button. Some fields are required and below the button is a ValidationSummary. The complete form is larger than screen height so one has to scroll down to reach the submit button. If I don't fill all required fields and click on submit validation fails as expected and the validation summary displays some info messages below the button. Validation happens on the client and no postback occurs. So this all works as wished. But disturbing is that the page moves ("jumps") to top position when I click on the submit button. To see the validation summary one has to move down the page again. I've tried to set the ShowSummary property to false (which doesn't make much sense): The validation still works (no postback) but in this case the page does not move to top position. So the problem seems to depend on rendering the validation texts. Is there a way to prevent this page jump? Thank you in advance!

• How to bring a modal to the front of the page using bootstrap?

  - by sharataka

  I am trying to implement a modal using bootstrap. When I click on the button the screen fades and the modal appears, but it appears behind the images in and is unreadable for the user. How do I bring the modal forward? <div class ="container-fluid"> <div class = "row-fluid"> <div class = "span2"> <!-- Modal --> <div class="modal hide fade" id="myModal"> <div class="modal-header"> <a class="close" data-dismiss="modal">×</a> <h3>Modal header</h3> </div> <div class="modal-body"> <p>One fine body…</p> </div> <div class="modal-footer"> <a href="#" class="btn">Close</a> <a href="#" class="btn btn-primary">Save changes</a> </div> </div> <a data-toggle="modal" href="#myModal" class="btn btn-primary">Launch demo modal</a> </div> <div class = "span8"> #a lot of images in this div </div> </div> </div>
