  • asp.net mvc 2: SportsStore application: The current request for action is ambiguous

    - by dotnet-practitioner
    I am working on SportsStore example on chapter 4 from the following book and getting stuck... Pro Asp.net mvc framework I get the following error: The current request for action 'List' on controller type 'ProductsController' is ambiguous between the following action methods: System.Web.Mvc.ViewResult List() on type WebUI.Controllers.ProductsController System.Web.Mvc.ViewResult List(Int32) on type WebUI.Controllers.ProductsController .. My router code looks as follows: public static void RegisterRoutes(RouteCollection routes) { routes.MapRoute( null, // Route name "", // URL with parameters new { controller = "Products", action = "List", page=1 } ); routes.MapRoute( null, // Route name "Page{page}", // URL with parameters new { controller = "Products", action = "List" }, // Parameter defaults new { page = @"\d+" } ); } and controller code looks as follows: public ViewResult List() { return View(productsRepository.Products.ToList()); } public ViewResult List(int page) { return View(productsRepository.Products .Skip((page - 1) * PageSize) .Take(PageSize) .ToList()); } What am I missing? my url is as follows: http://localhost:1103/ or http://localhost:1103/Page1 or http://localhost:1103/Page2 thanks

  • Clarity is important, both in question and in answer.

    - by gerrylowry
    clarity is important ... i'm often reminded of the Clouseau movie in which Peter Sellers as Chief Inspector Clouseau asks a hotel clerk "Does your dog bite?" ... the clerk answers "no" ... after Clouseau has been bitten by the dog, he looks at the hotel clerk who says "That's not my dog".  Clarity is important, both in question and in answer. i've been a member of forums.asp.net since 2008 ... like many of my peers at forums.asp.net, i've answered my fair share of questions. FWIW, the purpose of this, my first web log post to http://weblogs.asp.net/gerrylowry is to help new members ask better questions and in turn get better answers. TIMTOWTDI  =.  there is more than one way to do it imho, the best way to ask a question in any forum, or even person to person, is to first formulate your question and then ask yourself to answer your own question. Things to consider when asking (the more complete your question, the more likely you'll get the answer you require): -- have you searched Google and/or your favourite search engine(s) before posting your question to forums.asp.net; examples: site:msdn.microsoft.com entity framework 5.0 c#http://lmgtfy.com/?q=site%3Amsdn.microsoft.com+entity+framework+5.0+c%23 site:forums.asp.net MVC tutorial c#http://lmgtfy.com/?q=site%3Aforums.asp.net+MVC+tutorial+c%23 -- are you asking your question in the correct forum?  look at the forums' descriptions at http://forums.asp.net/; examples: Getting Started If you have a general ASP.NET question on a topic that's not covered by one of the other more specific forums - ask it here. MVC Discussions regarding ASP.NET Model-View-Controller (MVC) C# Questions about using C# for ASP.NET development Note:  if your question pertains more to c# than to MVC, choosing the C# forum is likely to be more appropriate. -- is your post subject clear and concise, yet not too vague? compare these three subjects (all three had something to do with GridView):     (1)    please help     (2)    gridview      (3)    How to show newline in GridView  -- have you clearly explained your scenario? compare:  my leg hurts   with   when i walk too much, my right knee hurts in the knee joint  compare:  my code does not work    with    when i enter a date as 2012-11-8, i get a FormatException -- have you checked your spelling, your grammar, and your English? for better or worse, English is the language of forums.asp.net ... many of the currently 170000++ forums.asp.net are not native speakers of English; that's okay ... however, there are times when choosing the more appropriate words will likely get one a better answer; fortunately, there are web tools to help you formulate your question, for example, http://translate.google.com/.  -- have you provided relevant information about your environment? here are a few examples ... feel free to include other items to your question ... rule of thumb:  if you think a given detail is relevant, it likely is -- what technology are you using?    ASP.NET MVC 4, ASP.NET MVC 3, WebForms, ...  -- what version of Visual Studio are you using?  vs2012 (ultimate, professional, express), vs2010, vs2008 ... -- are you hosting your own website?  are you using a shared hosting service? -- are you experience difficulties in just one browser? more than one browser? -- what browser version(s) are you using?   ie8? ie9? ... -- what is your operating system?     win8, win7, vista, XP, server 2008 R2 ... -- what is your database?   SQL Server 2008 R2, ss2005, MySQL, Oracle, ... -- what is your web server?  iis 7.5, iis 6, .... -- have you provided enough information for someone to be able to answer your question? Here's an actual example from an O.P. that i hope is self-explanatory: I'm trying to make a simple calculator when i write the code in windows application it worked when i tried it in web application it doesn't work and there are no errors what should i do ??!! -- have you included unnecessary information? more than once, i've seen the O.P. (original post, original poster) include many extra lines of code that were not relevant to the actual question; the more unnecessary code that you include, the less likely your volunteer peers will be motivated to donate their time to help you. -- have you asked the question that you want answered? "Does this dog bite?" -- are your expectations reasonable? -- generally, persons who are going to answer your questions are your peers ... they are unpaid volunteers ... -- are you looking for help with your homework, work assignment, or hobby? or, are you expecting someone else to do your work for you?  -- do you expect a complete solution or are you simply looking for guidance and direction? -- you are likely to get more help by first making a reasonable effort to help yourself first Clarity is important, both in question and in answer. if you are answering someone else's question, please remember that clear answers are just as important as clear questions; would you understand your own answer? Things to consider when answering: -- have you tested your code example?  if you have, say so; if you've not tested your code example, also say so -- imho, it's okay to guess as long as you clearly state that you're guessing ... sometimes a wrong guess can still help the O.P. find her/his way to the right answer -- meanness does not contribute to being helpful; sometimes one may become frustrated with the O.P. and/or others participating in a thread, if that happens to you, be kind regardless; speaking from my own experience, at least once i've allowed myself to be frustrated into writing something inappropriate that i've regretted later ... being a meany does not feel good ... being kind and helpful feels fantastic! Tip:  before asking your question, read more than a few existing questions and answers to get a sense of how your peers ask and answer questions. Gerry P.S.:  try to avoid necroposting and piggy backing. necroposting is adding to an old post, especially one that was resolved months ago. piggy backing is adding your own question to someone else's thread.

  • Where and which data to save into session on an ASP.NET MVC 2 application?

    - by Shaharyar
    I am having some trouble saving the state of my current view. Currenly I have several selectlist calling their own Action method on the controller that returns the Index view with the filtered model based on the values of the selectlist. I have also written a little FileResult action that creates a csv file based on the current model. But I am only covering one selectlist right now as I only save the value of selectList1 into the session and access it with Session["SelectListValue1"] What are the best practices in this situation? Should I redo the entire (each action for each SelectList) part? Should I save each SelectLists value into the session and check if it's null? Or should I just save the Lambda Expression into the session and modify it during every call?

  • Tables are not visible in SQL Server Management Studio but they are in Visual Studio using same acco

    - by Germ
    I'm experiencing a weird problem with a particular SQL login. When I connect to the server in Microsoft SQL Server Management Studio (2008) using this account, I cannot see any of the tables, stored procedures etc. that this account should have access to. When I connect to the same server within Visual Studio (2008) with the same account everything is there. I've also had a co-worker connect to the server using the same login and he's able to view everything as well. The strange thing is if I switch logins, I'm able to view objects that the other account has access to which indicates that there isn't a problem with MSSMS on my PC. Does anyone have any suggestions on how I can diagnose this problem? I've check to make sure I don't have any Table filters etc.

  • iPad split controller that doesn't hide the left pane in portrait

    - by Tim Norman
    I am trying to implement a split view controller like UISplitViewController on the iPad, but I don't want the left pane to be hidden when the device is in portrait orientation. So I've created a UIViewController subclass for this in IB and it works fine without any sub-view controllers. Now I'm trying to wrap my head around what is required to setup and manage the two UIViewController objects for the left and right panes. In my app, they are going to both be UINavigationController with a UITableView in them. I've hit a mental road block about how to set this up and was hoping someone could point me to some sample code or give me a recommendation for architecture here...

  • Asp.Net MVC style routing in Django

    - by Andrew Hanson
    I've been programming in Asp.Net MVC for quite some time now and to expand a little bit beyond the .Net world I've recently began learning Python and Django. I am enjoying Django but one thing I am missing from Asp.Net MVC is the automatic routing from my urls to my controller actions. In Asp.Net MVC I can build much of my application using this single default route: routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "" } // Parameter defaults ); In Django I've found myself adding an entry to urls.py for each view that I want to expose which leads to a lot more url patterns than I've become used to in Asp.Net MVC. Is there a way to create a single url pattern in Django that will handle "[Application]/view/[params]" in a way similar to Asp.Net MVC? Perhaps at the main web site level?

  • MVC Client Validation from Service Layer

    - by GibboK
    I'm following this article http://www.asp.net/mvc/tutorials/older-versions/models-(data)/validating-with-a-service-layer-cs to include a Service Layer with Business Logic in my MVC Web Application. I'm able to pass messages from the Service Layer to the View Model in a Html.ValidationSummary using ModelState Class. I perform basic validation logic on the View Model (using DataAnnotation attributes) and I have ClientValidation enabled by default which displaying the error message on every single field of my form. The Business logic error message which come from the Service Layer are being displayed on Html.ValidationSummary only after Posting the form to the Server. After Validation from the Service Layer I would like highlight one or more fields and have the message from the Service Layer showing on these fields instead that the Html.ValidationSummary. Any idea how to do it? Thanks

  • router connect configuration in cakephp 1.3

    - by Gaurav Sharma
    Hello everyone, I have defined the following rule in the router.php file of my cakephp 1.3 based application Router::connect('/tags/*',array('plugin' => 'tags', 'controller' => 'Tags', 'action' => 'index', 'admin' => false)); I have used the tags plugin. When I display the tags related to a topic then the URL on the tags appears something like this http://localhost/testapp/tags/Tags/view/{tag_key_name} I want to make this url for any action to tags plugin like this http://localhost/testapp/Tags/{action}/{tag_key_name} for (view, admin_view and admin_edit) and http://localhost/testapp/Tags/{action} for (index, admin_index and any other action that does not require an id or keyname for execution)

  • Comparing ASP.Net Framework to Cakephp, Zend , Ruby on Rails

    - by numerical25
    I am a PHP developer migrating to C# ASP.Net Framework. As of right now, I am experienced in using Php for developing sites and I use CakePhp and Zend framework as my RAD tools to help me produce better applications. As I move over to ASP.NET, I have this view that C# ASP.Net framework itself is already a RAD tool and is equivalent to using Cakephp, Zend, or even Ruby on Rails. So I really shouldn't have no concerns trying to find a separate library for ASP.NET that will help me produce better applications. To me, in a sense the ASP.NET is already like a MVC cause it seperates the model from the view and the methods are almost like controllers. So as far as having the best tools are concerned, should I be satisfied with just using ASP.NET as my RAD tool.

  • INSERT OR IGNORE in a trigger

    - by dan04
    I have a database (for tracking email statistics) that has grown to hundreds of megabytes, and I've been looking for ways to reduce it. It seems that the main reason for the large file size is that the same strings tend to be repeated in thousands of rows. To avoid this problem, I plan to create another table for a string pool, like so: CREATE TABLE AddressLookup ( ID INTEGER PRIMARY KEY AUTOINCREMENT, Address TEXT UNIQUE ); CREATE TABLE EmailInfo ( MessageID INTEGER PRIMARY KEY AUTOINCREMENT, ToAddrRef INTEGER REFERENCES AddressLookup(ID), FromAddrRef INTEGER REFERENCES AddressLookup(ID) /* Additional columns omitted for brevity. */ ); And for convenience, a view to join these tables: CREATE VIEW EmailView AS SELECT MessageID, A1.Address AS ToAddr, A2.Address AS FromAddr FROM EmailInfo LEFT JOIN AddressLookup A1 ON (ToAddrRef = A1.ID) LEFT JOIN AddressLookup A2 ON (FromAddrRef = A2.ID); In order to be able to use this view as if it were a regular table, I've made some triggers: CREATE TRIGGER trg_id_EmailView INSTEAD OF DELETE ON EmailView BEGIN DELETE FROM EmailInfo WHERE MessageID = OLD.MessageID; END; CREATE TRIGGER trg_ii_EmailView INSTEAD OF INSERT ON EmailView BEGIN INSERT OR IGNORE INTO AddressLookup(Address) VALUES (NEW.ToAddr); INSERT OR IGNORE INTO AddressLookup(Address) VALUES (NEW.FromAddr); INSERT INTO EmailInfo SELECT NEW.MessageID, A1.ID, A2.ID FROM AddressLookup A1, AddressLookup A2 WHERE A1.Address = NEW.ToAddr AND A2.Address = NEW.FromAddr; END; CREATE TRIGGER trg_iu_EmailView INSTEAD OF UPDATE ON EmailView BEGIN UPDATE EmailInfo SET MessageID = NEW.MessageID WHERE MessageID = OLD.MessageID; REPLACE INTO EmailView SELECT NEW.MessageID, NEW.ToAddr, NEW.FromAddr; END; The problem After: INSERT OR REPLACE INTO EmailView VALUES (1, '[email protected]', '[email protected]'); INSERT OR REPLACE INTO EmailView VALUES (2, '[email protected]', '[email protected]'); The updated rows contain: MessageID ToAddr FromAddr --------- ------ -------- 1 NULL [email protected] 2 [email protected] [email protected] There's a NULL that shouldn't be there. The corresponding cell in the EmailInfo table contains an orphaned ToAddrRef value. If you do the INSERTs one at a time, you'll see that Alice's ID in the AddressLookup table changes! It appears that this behavior is documented: An ON CONFLICT clause may be specified as part of an UPDATE or INSERT action within the body of the trigger. However if an ON CONFLICT clause is specified as part of the statement causing the trigger to fire, then conflict handling policy of the outer statement is used instead. So the "REPLACE" in the top-level "INSERT OR REPLACE" statement is overriding the critical "INSERT OR IGNORE" in the trigger program. Is there a way I can make it work the way that I wanted?

  • Databind List Of Objects To A WinForms DataGridView, But Not Show Certain Public Properties

    - by Pyronaut
    I'm not even sure if i'm doing this correctly. But basically I have a list of objects that are built out of a class. From there, I am binding the list to a datagrid view that is on a Windows Form (C#) From there, it shows all the public properties of the object, in the datagrid view. However there is some properties that i still need accessible from other parts of my application, but aren't really required to be visible in the DataGridView. So is there an attribute or something similar that I can write above the property to exclude it from being shown. P.S. Im binding at runtime. So i cannot edit the columns via the designer. P.P.S. Please no answers of just making public variables (Although if that is the only way, let me know :)).

  • ASP.Net MVC - Build a load on demand TreeView

    - by Eric P
    I am wondering how to build a load on demand tree view using ASP.Net MVC. I understand what is involved in creating a JQuery TreeView using lists, but the load on demand part is really confusing me. I don't need the full solution, but can somebody point me in the right direction on where I should start? I have done these plenty of times using WinForms which keeps the view state preserved. One of the issues I am seeing is remembering all the node that have been expanded and not just the newly expanded one. If anyone had some advice, I would appreciate it. Thanks!

  • Follow up viewDidUnload vs. dealloc question...

    - by entaroadun
    Clarification question as a follow up to: http://stackoverflow.com/questions/2261972/what-exactly-must-i-do-in-viewdidunload http://stackoverflow.com/questions/1158788/when-should-i-release-objects-in-voidviewdidunload-rather-than-in-dealloc So let's say there's a low memory error, and the view is hidden, and viewDidUnload is called. We do the release and nil dance. Later the entire view stack is not needed, so dealloc is called. Since I already have the release and nil stuff in viewDidUnload, I don't have it in dealloc. Perfect. But if there's no low memory error, viewDidUnload is never called. dealloc is called and since I don't have the release and nil stuff, there's a memory leak. In other words, will dealloc ever be called without viewDidUnload being called first? And the practical follow up to that is, if I alloc and set something in viewDidLoad, and I release it and set to nil in viewDidUnload, do I leave it out of dealloc, or do I do a defensive nil check in dealloc and release/nil it if it's not nil?

  • UIView transparency shows how the sausages are made!

    - by quixoto
    I have a UIView container that has two UIImageViews inside it, one partially obscuring the other (they're being composed like this to allow for occasional animation of one "layer" or another. Sometimes I want to make this container 50% alpha, so what the users sees fades. Here's the problem: setting my container view to 50% alpha makes all my subviews inherit this as well, and now you can see through the first subview into the second, which in my application has a weird X-Ray effect that I'm not looking for. What I'm after, of course, is for what the user currently sees to become 50% transparent-- the equivalent of flattening the visible view into one bitmap, and then making that 50% alpha. What are my best bets for accomplishing this? Ideally would like to avoid actually, dynamically flattening the views if I can help it, but best practices on that welcome as well. Am I missing something obvious? Since most views have subviews and would run into this issue, I feel like there's some obvious solution here. Thanks!

  • How to get ID of EditorFor with nested viewmodels in asp.net mvc 2

    - by Luke
    So I have two nested view models, CreditCard - BillAddress. I have a view, "EditBilling", that has EditorFor(CreditCard). The CreditCard EditorTemplate has EditorFor(BillAddress), and the BillAddress EditorTemplate has EditorFor(BillState). The end result is a select list with id "CreditCard_BillAddress_BillState". I need to reference this in javascript, thus need to know the ID. In other situations, with non-nested ViewModels, I have used the following code: $('#<%= ViewData.ModelMetadata.PropertyName %>_BillState') The problem here is that the ModelMetadata.PropertyName property is only aware of the current property, not the parent(s). So I end up with the following: $('#BillAddress_BillState') How does one go about getting the client ID of nested strongly typed helpers? Thanks in advance.

  • Using Yii framework, what would be a right way to process an attribute before displaying it using CH

    - by Karolis
    Say I have this line of code in the view. <?php echo CHtml::activeTextField($model,'start_time'); ?> start_time is a UNIX timestamp. When just displaying it in a view I can apply functions like date() on it. Where should I apply the formatting when I'm displaying it in a form, by using the above line of code? (This case of timestamps/dates might be special, but I'm also interested in how would one go about if it wasn't a date and I just want to work with "value in database" < "different representations of the value in different views. Thanks =)

  • Is it possible to drag windows between workspaces when using Compiz?

    - by Mike Stone
    When I used Metacity, I could drag windows between workspaces using the small icon view of my workspaces. I recently started using Compiz for all the cool desktop effects, however this drag and drop feature isn't working. I use the cube effect for switching workspaces, but I noticed the wall effect doesn't allow it either. Is this just a missing feature from Compiz or is there a setting somewhere that I can enable it? I know that I can enable dragging windows across edges to the next workspace, and the expose feature to drag windows between workspaces. However, the drag and drop on the icon view is really powerful, and I would love to have it back along with all the great Compiz special effects.

  • Why my own UIViewController can't detect touch?

    - by Tattat
    I have my OwnViewController, the viewDidLoad is like this: - (void)viewDidLoad { [super viewDidLoad]; UIImage *img = [UIImage imageWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"myImg" ofType:@"png"]]; CGRect cropRect = CGRectMake(175, 0, 175, 175); CGImageRef imageRef = CGImageCreateWithImageInRect([img CGImage], cropRect); UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 175, 175)]; imageView.image = [UIImage imageWithCGImage:imageRef]; self.view = imageView; CGImageRelease(imageRef); } It works, and I have detect touches method like this: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { NSLog(@"touchesBegan"); } But my UIView can't detect any touches. My Own UIViewController is a subclass of UIViewController. It is a little square view on the IB, why that can't detect touches? thx u.

  • How do I remove those rotation artefacts from my CATiledLayer?

    - by Felix
    Hello all, I have a CATiledLayer into which I render content in the following method - (void)drawLayer:(CALayer *)layer inContext:(CGContextRef)ctx I used the QuartzDemo code to draw a pattern. This works very well until I apply a rotation transform to the layer's parentLayer (a UIView): rotated: These zigzag artefacts become worse when I start drawing lines and texts into the CATiledLayer. I applied the transform as follows (I also tried using an affine transform on the view itself): self.containerView.layer.transform = CATransform3DMakeRotation(angleRadians, 0.0f, 0.0f, 1.0f); I transform the containerView rather than the layer itself, as I have several layers in that view that I would like to rotate at the same time without changing the relative positions. I did not have problems when rotating UIImageViews in the past. Is there a way that I can rotate the CATiledLayer without these problems? Any help would be greatly appreciated. Yours, Felix

  • My presentation layer does not match my model layer even though I have no animations

    - by Kevin McCullough
    On iPhone I have a CALayer that I animate via Core Animation. Then at some point I change view controllers. I then return to the view controller with the CALayer and in viewWillAppear: I set the frame and position properties on my layer to move it back to its starting point. Setting these properties changes the model layer but the presentation layer still has the old values and its presentation layer does not update until the next animation I play. In the CA Programming guide it says "You can query an instance of CALayer for its corresponding presentation layer while an animation transaction is in process." Which, to me, implies that the presentation layer should only be different from the model layer during an animation. But there are no animations currently running. I even used kCATransactionDisableActions to ensure that when I set the position property an implicit animation is not started. Does anyone know why my presentation and model layers are out of sync? Thanks.
