• Html.RadioButton throw exception during rendering after server validation

  Let me first illustrate how the problem arises. Here it is an extract of the view: <%= Html.RadioButton("MembershipType", "0")%> Classic<br /> <%= Html.RadioButton("MembershipType", "1")%> Premier <%= Html.ValidationMessage("MembershipType", "*")%> Initially both radio buttons are cleared (i.e. no radio button selected). Upon submitting the form, the form contains no posted data for "MembershipType" which

• Possible bug arrised from validating RadioButton without state that causes exception in MVC RC2

  In the MVC RC2 source code file HtmlHelper.cs there is the following method definition: internal object GetModelStateValue(string key, Type destinationType) { ModelState modelState; if (ViewData.ModelState.TryGetValue(key, out modelState)) { return modelState.Value.ConvertTo(destinationType, null /* culture */); } return null; } In somes cases modelState.Value can be null in which case the above throws exception. It is null in the following scenario: I have the following in my view: <%= Html.RadioButton

• ASP.NET MVC RC 1 Source Code version

  Does anyone know if the RC source code available at codeplex corresponds to ASP.NET MVC RC Refresh (as the post by Phil Haack ) or the original published ASP.NET MVC RC version? The AssemblyFileVersion on the source code is 1.0.40112.0 whereas the new refresh binary (DLL) version is 1.0.40128.0. Based on that, I assume that the source code refers to the old MVC RC version and not the refreshed version.

• Re: How to pass a value from View t to MasterPage

  That it is strange check your web.config file to make sure you have the following declared: < pages > < namespaces > < add namespace = " System.Web.Mvc " /> < add namespace = " System.Web.Mvc.Html " /> </ namespaces > </ pages > If that doesn't work. I suggest create a new MVC Web App using the visual studio wizard. Then compare that created web.config file with yours. You'll see that the created master page file makes reference to ViewData

• Re: How to pass a value from View t to MasterPage

  I believe the MasterPage is rendered/loaded before your view, therefore if in your view you change/assign something to ViewData, the MasterPage won't see the change/added item as it is already rendered. You should set the viewdata in your controller action, this way your masterpage will be able to use it.

• Re: MVC Beta - setting Properties on UserControls

  Yes you can . Here is an example from parts of my application: Your view has to be strong typed, e.g. public partial class Personal : ViewPage < SkillsContentModel > Then inside that view you call render partial as e.g.: < div id ="SkillsContainer"> <% Html . RenderPartial ("SkillsContent"); %> </ div > Note that by not explicitely specifying any viewdata or model, you are passing the parent view model to the partial view user control. Your usercontrol

• Re: using jquery error function

  You cannot access the viewdata because that's on the server. JQuery is on the client side, so therefore you don't have access to viewdata or any server data. The ajax error function receives 3 parameters (the below is from JQuery documentation): error: function (XMLHttpRequest, textStatus, errorThrown) { // typically only one of textStatus or errorThrown // will have info this; // the options for this ajax request }

• Re: using jquery error function

  First of all your controller will need the [ HandleError ] attribute or you can add the attribute individually to each of your action methods. When an unhandled exception is thrown in your method (or methods that it calls). The controller causes Error.aspx page to display the error. Your method should look something like: public ActionResult MyMethod ( int rating ) { return Json ( new { Average = rating , Count = "119" }); } If you want to test your Jquery error handler, throw an exception

• Re: Using the ViewData dictionary

  The problem is that you must be storing the url in your ViewData.Model. The reason why <%= Html.TextBox("UrlName", ViewData["UrlName"]) %> works is because ViewData["UrlName"] is null and therefore MVC internally uses something similar to DataBinder.Eval(ViewData.Model, "UrlName") when the parameter is null. Therefore either in your controller store the Url directly in the viewdata, e.g.: ViewData["UrlName"] = "something"; Or use ViewData
