  • Rogue PropertyChanged notifications from ViewModel

    - by user1886323
    The following simple program is causing me a Databinding headache. I'm new to this which is why I suspect it has a simple answer. Basically, I have two text boxes bound to the same property myString. I have not set up the ViewModel (simply a class with one property, myString) to provide any notifications to the View for when myString is changed, so even although both text boxes operate a two way binding there should be no way that the text boxes update when myString is changed, am I right? Except... In most circumstances this is true - I use the 'change value' button at the bottom of the window to change the value of myString to whatever the user types into the adjacent text box, and the two text boxes at the top, even although they are bound to myString, do not change. Fine. However, if I edit the text in TextBox1, thus changing the value of myString (although only when the text box loses focus due to the default UpdateSourceTrigger property, see reference), TextBox2 should NOT update as it shouldn't receive any updates that myString has changed. However, as soon as TextBox1 loses focus (say click inside TextBox2) TextBox2 is updated with the new value of myString. My best guess so far is that because the TextBoxes are bound to the same property, something to do with TextBox1 updating myString gives TextBox2 a notification that it has changed. Very confusing as I haven't used INotifyPropertyChanged or anything like that. To clarify, I am not asking how to fix this. I know I could just change the binding mode to a oneway option. I am wondering if anyone can come up with an explanation for this strange behaviour? ViewModel: namespace WpfApplication1 { class ViewModel { public ViewModel() { _myString = "initial message"; } private string _myString; public string myString { get { return _myString; } set { if (_myString != value) { _myString = value; } } } } } View: <Window x:Class="WpfApplication1.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfApplication1" Title="MainWindow" Height="350" Width="525"> <Window.DataContext> <local:ViewModel /> </Window.DataContext> <Grid> <!-- The culprit text boxes --> <TextBox Height="23" HorizontalAlignment="Left" Margin="166,70,0,0" Name="textBox1" VerticalAlignment="Top" Width="120" Text="{Binding Path=myString, Mode=TwoWay}" /> <TextBox Height="23" HorizontalAlignment="Left" Margin="166,120,0,0" Name="textBox2" VerticalAlignment="Top" Width="120" Text="{Binding Path=myString, Mode=TwoWay}"/> <!--The buttons allowing manual change of myString--> <Button Name="changevaluebutton" Content="change value" Click="ButtonUpdateArtist_Click" Margin="12,245,416,43" Width="75" /> <Button Content="Show value" Height="23" HorizontalAlignment="Left" Margin="12,216,0,0" Name="showvaluebutton" VerticalAlignment="Top" Width="75" Click="showvaluebutton_Click" /> <Label Content="" Height="23" HorizontalAlignment="Left" Margin="116,216,0,0" Name="showvaluebox" VerticalAlignment="Top" Width="128" /> <TextBox Height="23" HorizontalAlignment="Left" Margin="116,245,0,0" Name="changevaluebox" VerticalAlignment="Top" Width="128" /> <!--simply some text--> <Label Content="TexBox1" Height="23" HorizontalAlignment="Left" Margin="99,70,0,0" Name="label1" VerticalAlignment="Top" Width="61" /> <Label Content="TexBox2" Height="23" HorizontalAlignment="Left" Margin="99,118,0,0" Name="label2" VerticalAlignment="Top" Width="61" /> </Grid> </Window> Code behind for view: namespace WpfApplication1 { /// <summary> /// Interaction logic for MainWindow.xaml /// </summary> public partial class MainWindow : Window { ViewModel viewModel; public MainWindow() { InitializeComponent(); viewModel = (ViewModel)this.DataContext; } private void showvaluebutton_Click(object sender, RoutedEventArgs e) { showvaluebox.Content = viewModel.myString; } private void ButtonUpdateArtist_Click(object sender, RoutedEventArgs e) { viewModel.myString = changevaluebox.Text; } } }

  • Creating DOM elements on the fly - check if the data is not harmful

    - by user313353
    I already posted a question closely related to the this one. I watched the Mix10 video with P. Haacked and S. Hanselman. I am building an AJAX-powered site whose input forms are created on the fly. All the code to accomplish this is done within a script tag or a javascript file. For example the following DOM elements are created when the page loads and are wrapped into an existing div defined in a view: $('#myform').append('); $('#myform').append(''); When I click the submit button I need to get the values of the input form whose id is 'Name': $("#Name").val() and then I return a Json object: { Name: name }; For this kind of scenario there is no way to use Html.Encode() or AntiXss.HtmlEncode() on the client-side. The only way to check if the input is not harmful is done on the server-side (via a service layer). This seems a limitation. All is fine if and only if a view has a set of predefined inputs. When it is time to create them on the fly, the situation is different. Have you thought of that situation guys? Thanks for the attention you have put on this. Roland Brussels, Belgium

  • How do you use jQuery .data() to store html?

    - by Al
    Hi all - when I look up the syntax for .data(), it gives examples like this: $('body').data('foo', 52); I am doing AJAX loads and I was wondering if it is possible to store the incoming html using .data() so once the content is loaded, I would not need to do another AJAX load if the same link is clicked again - I would check to see if the .data key is empty. Would something like this work?: To load the contents of a #ajaxdiv into storage: $('body').data('storage', div#ajaxdiv.html()); To test if the data has already been loaded: if $('body').data('storage') != '' { div#ajaxdiv.html($('body').data('storage')); } Thanks in advance!!

  • Calling a function that resides in the main page from a plugin?

    - by Justin Lee
    I want to call a function from within plugin, but the function is on the main page and not the plugin's .js file. EDIT I have jQuery parsing a very large XML file and building, subsequently, a large list (1.1 MB HTML file when dynamic content is copied, pasted, then saved) that has expand/collapse functionality through a plugin. The overall performance on IE is super slow and doggy, assuming since the page/DOM is so big. I am currently trying to save the collapsed content in the event.data when it is collapsed and remove it from the DOM, then bring it back when it is told to expand... the issue that I am having is that when I bring the content back, obviously the "click" and "hover" events are gone. I'm trying to re-assign them, currently doing so inside the plugin after the plugin expands the content. The issue then though is that is says the function that I declare within the .click() is not defined. Also the hover event doesn't seem to be re-assigning either.... if ($(event.data.trigger).attr('class').indexOf('collapsed') != -1 ) { // if expanding // console.log(event.data.targetContent); $(event.data.trigger).after(event.data.targetContent); $(event.data.target).hide(); /* This Line --->*/ $(event.data.target + 'a.addButton').click(addResourceToList); $(event.data.target + 'li.resource') .hover( function() { if (!($(this).attr("disabled"))) { $(this).addClass("over"); $(this).find("a").css({'display':'block'}); } }, function () { if (!($(this).attr("disabled"))) { $(this).removeClass("over"); $(this).children("a").css({'display':'none'}); } } ); $(event.data.target).css({ "height": "0px", "padding-top": "0px", "padding-bottom": "0px", "margin-top": "0px", "margin-bottom": "0px"}); $(event.data.target).show(); $(event.data.target).animate({ height: event.data.heightVal + "px", paddingTop: event.data.topPaddingVal + "px", paddingBottom: event.data.bottomPaddingVal + "px", marginTop: event.data.topMarginVal + "px", marginBottom: event.data.bottomMarginVal + "px"}, "normal");//, function(){$(this).hide();}); $(event.data.trigger).removeClass("collapsed"); $.cookies.set('jcollapserSub_' + event.data.target, 'expanded', {hoursToLive: 24 * 365}); } else if ($(event.data.trigger).attr('class').indexOf('collapsed') == -1 ) { // if collapsing $(event.data.target).animate({ height: "0px", paddingTop: "0px", paddingBottom: "0px", marginTop: "0px", marginBottom: "0px"}, "normal", function(){$(this).hide();$(this).remove();}); $(event.data.trigger).addClass("collapsed"); $.cookies.set('jcollapserSub_' + event.data.target, 'collapsed', {hoursToLive: 24 * 365}); } EDIT So, having new eyes truly makes a difference. As I was reviewing the code in this post this morning after being away over the weekend, I found where I had err'd. This: $(event.data.target + 'a.addButton').click(addResourceToList); Should be this (notice the space before a.addbutton): $(event.data.target + ' a.addButton').click(addResourceToList); Same issue with the "li.resource". So it was never pointing to the right elements... Thank you, Rene, for your help!!

  • Why use hashing to create pathnames for large collections of files?

    - by Stephen
    Hi, I noticed a number of cases where an application or database stored collections of files/blobs using a has to determine the path and filename. I believe the intended outcome is a situation where the path never gets too deep, or the folders ever get too full - too many files (or folders) in a folder making for slower access. EDIT: Examples are often Digital libraries or repositories, though the simplest example I can think of (that can be installed in about 30s) is the Zotero document/citation database. Why do this? EDIT: thanks Mat for the answer - does this technique of using a hash to create a file path have a name? Is it a pattern? I'd like to read more, but have failed to find anything in the ACM Digital Library

  • Altering ManagedObjects In NSArray

    - by Garry
    I have an entity called 'Job' with two boolean attributes named 'completed' and 'logged'. I am trying to retrieve all completed jobs that have not been logged at app start-up and change them to logged. I'm able to get all the completed but unlogged jobs with this fetchRequest: NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(completed == %@ && logged == %@)", [NSNumber numberWithBool:YES], [NSNumber numberWithBool:NO]]; I'm then assigning this predicate to a fetchRequest and calling the [managedObjectContext executeFetchRequest:fetchRequest] method to get an array of all Job entities that meet this criteria. This seems to work fine and is returning the correct number of jobs. What I've been trying to do is loop through the NSArray returned, set the logged attribute to YES and then save. This seems to complete and doesn't return any errors but the changes are not persisted when the application quits. Where am I going wrong? [fetchRequest setPredicate:predicate]; NSError error; NSArray jobsToLog = [managedObjectContext executeFetchRequest:fetchRequest error:&error]; if ([jobsToLog count] > 0) { for (int i = 0; i < [jobsToLog count] - 1; i++) { [[jobsToLog objectAtIndex:i] setLogged:[NSNumber numberWithBool:YES]]; // Commit the changes made to disk error = nil; if (![managedObjectContext save:&error]) { // An error occurred } } } Thanks in anticipation,

  • What is the difference between declaring data attributes inside or outside __init__

    - by user1898540
    I'm trying to get my head around OOP in Python and I'm a bit confused when it comes to declare variables within a class. Should I declare them inside of the __init__ procedure or outside it? What's the difference? The following code works just fine: # Declaring variables within __init__ class MyClass: def __init__(self): country = "" city = "" def information(self): print "Hi! I'm from %s, (%s)"%(self.city,self.country) me = MyClass() me.country = "Spain" me.city = "Barcelona" me.information() But declaring the variables outside of the __init procedure also works: # Declaring variables outside of __init__ class MyClass: country = "" city = "" def information(self): print "Hi! I'm from %s, (%s)"%(self.city,self.country) me = MyClass() me.country = "Spain" me.city = "Barcelona" me.information()

  • Merge two lists of objects which hold different data

    - by C.McAtackney
    I have an object "Project" which has a number of fields, one of which is "Name". I have one spreadsheet of projects which contains some of these fields, and another which contains the rest. However, Both spreadsheets have the "Name" field. I've read them in and populated two List, only populating the available fields from that particular source. E.g. a Project from List 1 looks like; {Name="MyProj", Type="Form", Priority=NULL}, whereas a Project from List 2 {Name="MyProj", Type=NULL, Priority="High"}. Now, I want to merge these two lists into one in which each Project object has all of its fields populated, with the Name field being used to match the elements. How can I achieve this? Are there any nice ways of doing this concisely? Thanks

  • DataTriggered animation is triggered only in the first time

    - by Pavel
    I just wanted to create very simple example of DataTriggers and animation. Two checkboxes and Rectangle. Checking the first cb makes the rectangle fade away. (CodeBehind var is true) Checking the second cb makes the rectangle come back. (var is false) App is loading - the rectangle is showing (true) Firs cb is checked by default. I'm checking second cb - rect is dissapearing. It's OK. But when I then check the first cb rect isn't showing up. But checking the second cb still makes rect show up and fade away. here's my xaml and code behind: <StackPanel> <RadioButton IsChecked="True" Checked="RadioButton_Checked"></RadioButton> <RadioButton Checked="RadioButton_Checked_1"></RadioButton> <Rectangle Name="r1" Width="100" Height="300" Fill="Green"> <Rectangle.Style> <Style TargetType="Rectangle"> <Style.Triggers> <DataTrigger Binding="{Binding Active}" Value="True"> <DataTrigger.EnterActions> <BeginStoryboard> <Storyboard> <DoubleAnimation Storyboard.TargetProperty="Opacity" From="0" To="1" Duration="0:0:1" /> </Storyboard> </BeginStoryboard> </DataTrigger.EnterActions> </DataTrigger> <DataTrigger Binding="{Binding Active}" Value="False"> <DataTrigger.EnterActions> <BeginStoryboard> <Storyboard> <DoubleAnimation Storyboard.TargetProperty="Opacity" From="1" To="0" Duration="0:0:1" /> </Storyboard> </BeginStoryboard> </DataTrigger.EnterActions> </DataTrigger> </Style.Triggers> </Style> </Rectangle.Style> </Rectangle> </StackPanel> public bool Active { get { return (bool) GetValue(ActiveProperty); } set { SetValue(ActiveProperty, value); } } public static readonly DependencyProperty ActiveProperty = DependencyProperty.Register("Active", typeof(bool), typeof(MainWindow), new UIPropertyMetadata(false)); private void RadioButton_Checked(object sender, RoutedEventArgs e) { Active = true; } private void RadioButton_Checked_1(object sender, RoutedEventArgs e) { Active = false; }

  • Why does dynamic array always double by a factor of 2?

Why 2? Why not 3? how does one decide this factor ? IF it is language dependent I would like to know this for Java.

  • Having problems creating an array from XML data in Acrobat Javascript, please help if you can

    - by Kevin Minke
    I have a manually created array that already works example below: var PartsData = { 179: { ref:"", partNum: "201-2007-C00-00", descript: "System Monitor Card (Tracewell Only)", cage: "39764", qty: "1", SMR: "XBOZZ", UOC: "A" }}; Now this array above is is just one value in the array and it works fine. Here is the XML that I am trying to use to dynamically change the values. <?xml version="1.0" encoding="utf-8"?> <partsTables> <partsList> <part sheetNum="ta1"> <breakDownIndexNo>-1 </breakDownIndexNo> <referenceDesg/> <indent>20534220P01 </indent> <description/> <cage>TAC RI, GRADE-A SHOCK (TEC RACK), ALT P/N 72304-1</cage> <qtyPerAssy>23991 </qtyPerAssy> <smr>1 </smr> <uoc>ADODD </uoc> <blank/> </part> </partsList> </partsTables> I have this parsing just fine in Acrobat. Now I want to make the array work for me in using these values. if I have the following below it will work. Where part.item(i).indent.value equals the value of the indent node, etc. newArr = { 179: { ref: part.item(i).referenceDesg.value, partNum: part.item(i).indent.value, descript: part.item(i).cage.value, cage: part.item(i).qtyPerAssy.value, qty: part.item(i).smr.value, SMR: part.item(i).uoc.value, UOC: part.item(i).blank.value}}; As soon as I try to make the 179 value, which is in the breakDownIndexNo node, dynamic by using the direct part.item(i).breakDownIndexNo.value it will not compile. Acrobat is using javascript so I'm not sure why I can not get this to parse. I have tried to create a variable out of the breakDownIndexNo node and typed it to both a String and an Integer. this will let it create the array but it will not let me output from the array. newArr[indexNum].partNum gives me "no properties" where newArr[179].partNum if I were to manually set the index number to 179 will print out the value of part.item(i).indent.value. If any of you have an idea or an answer please let me know.

  • Nested Data XML design

    - by esryl
    Looking to nest (to unlimited levels) elements in XML. Like so: <items> <item> <name>Item One</name> <item> <name>Item Two</name> </item> <item> <name>Item Three</name> <item> <name>Item Four</name> </item> <!-- etc... --> </item> </item> </items> However. While browsing for a solution I noticed in the comments of: http://stackoverflow.com/questions/988139/weird-nesting-in-xml while the above is well formed it would not validate against any sinsible DTD. Two things, what is a better way of nesting similar elements, and secondly what would be the design of the DTD. UPDATE: Would prefer to validate against an XML Schema rather than DTD.

  • True or False: Good design calls for every table to have a primary key, if nothing else, a running i

    - by Velika
    Consider a grocery store scenario (I'm making this up) where you have FACT records that represent a sale transaction, where the columns of the Fact table include SaleItemFact Table ------------------ CustomerID ProductID Price DistributorID DateOfSale Etc Etc Etc Even if there are duplicates in the table when you consider ALL the keys, I would contend that a surrogate running numeric key (i.e. identity column) should be made up, e.g., TransactionNumber of type Integer. I can see someone arguing that a Fact table might not have a unique key (though I'd invent one and waste the 4 bytes, but how about a dimension table?

  • Ruby on Rails : How can i display data for the current view from a different table

    This might be a easy-to-answer question, but its a pain in the bum for me.... So... I have two tables - Chords - |id|chord|name|rating|artist_id| Artists - |id|artist| (the relations : chords : belongs_to :artist artists : has_many :chords ) And in the index page for "chords" i want to display chord,name,rating from Chords table AND artist from the Artists table this is the code for the chrod's index.html.erb : <table border="1"> <%@chords.each do |chord|%> <tr> <td><%=chord.artist.artist%></td> <td><%= link_to chord.name, chord %></td> <td><%=chord.rating%></td> <td><%= chord.created_at %></td> </tr> <%end%> </table> The error message is : undefined method `artist' for nil:NilClass Actually, at first it worked, but when i started to create the "new.html.erb" page and the create,new controllers, it stopped working - thats why this is so confusing for me! I will be glad to hear any critique and suggestions! Thank you

  • Serial numbers generation without user data

    - by Sphynx
    This is a followup to this question. The accepted answer is generally sufficient, but requires user to supply personal information (e.g. name) for generating the key. I'm wondering if it's possible to generate different keys based on a common seed, in a way that program would be able to validate if those keys belong to particular product, but without making this process obvious to the end user. I mean it could be a hash of product ID plus some random sequence of characters, but that would allow user to guess potential new keys. There should be some sort of algorithm difficult to guess.
