For fields in my ASP.NET MVC view that have been attributed as required, is there any way for the framework to render some sort of indicator automatically that the field is marked as required in metadata? Should be able to do this with CSS since MVC3 adds in those custom attributes to the element: <input data-val="true" data-val-required="The Username field is required." id="Username" name="Username" type="text" value="" /> You could key off the data-val-required in CSS like so: input[data-val-required] { background:red } or set a background image of an asterisk etc. I did that way because my

I have a question that has pretty much been asked here: asp.net mvc Html.ActionLink() keeping route value I don't want However, the final solution is a kludge, pure and simple and I really would like to understand why this happens, if someone can please explain it to me? For completeness, it is possible to recreate the scenario very easily: Create a new MVC web app. Run it up. Visit the About tab Modify the URL to read /Home/About/Flib - This obviously takes you to the action with an id of 'Flib' which we don't care about. Notice that the top menu link to About now actually links to /Home

I'm working my ASP.NET MVC 2 project. I create exception filter for catching unauthorized access exception that occur when user does not has permission to view some action. [CustomError(typeof(UnauthorizedAccessException), "Error", "UnauthorizedAccess")] public class MyController : BaseController { } After exception has been thrown, my filter will transfer to configured controller/action that is the following method. public ActionResult UnauthorizedAccess(ExceptionContext context) { Response.StatusCode = CustomHttpStatusCode.UnauthorizedUser; return View(model); } Finally, before ASP.NET

I read on some post, but cant find it now that in MVC 3 it was not really needed to create a Validator, only the Attribute. Is this true? I do say I find it confusing that the attribute has the IClientValidatable on it. So what does the DataAnnotationsModelValidator class do if the annotation has the client side script name (IClientValidatable), and the ability to validate (ValidationAttribute IsValid)? It would be really nice if I didnt have to register the Attribute with the Validator in the global. Can this be done? Did I read some bad advise? EDIT: Interestingly enough I just tested it by

I'm trying to do this simple thing <%= Html.HiddenFor(model => model.Id)%> the model is [HiddenInput(DisplayValue=true)] public int Id { get; set; } but i always get this rendered <input type="hidden" value="0" name="UserInfo.Id" id="UserInfo_Id"> i've check and the id is NOT 0.. ?! need some explanation here... Edit The problem seem's to be the post thing mentionned below. This is working <input type="hidden" value="<%= Html.AttributeEncode(Model.Id) %>" id="<%= Html.IdFor(model=>model.Id)%>" name="<%= Html.NameFor(model=>model.Id)%>" /> Thanks to Manaf Manaf Abu.Rous I'm not sure if this is

I'm using ASP.NET MVC and I need to set a session variable at Application_BeginRequest . The problem is that at this point the object HttpContext.Current.Session is always null . protected void Application_BeginRequest(Object sender, EventArgs e) { if (HttpContext.Current.Session != null) { //this code is never executed, current session is always null HttpContext.Current.Session.Add("__MySessionVariable", new object()); } } Pankaj Try AcquireRequestState in Global.asax. Session is available in this event which fires for each request: void Application_AcquireRequestState(object sender,

I am using jQuery.load() to render a partial view. This part looks like this: $('#sizeAddHolder').load( '/MyController/MyAction', function () { ... }); The code for actions in my controller is the following: public ActionResult MyAction(byte id) { var model = new MyModel { ObjectProp1 = "Some text" }; return View(model); } [HttpPost] public ActionResult MyAction(byte id, FormCollection form) { // TODO: DB insert logic goes here var result = ...; return Json(result); } I am returning a partial view that looks something like this: <% using (Html.BeginForm("MyAction", "MyController")) {%> <%=

I'm trying to create a view that contains a list of checkboxes that is dynamically created from a database, and then retrieve the list of selected ones when the form is posted back.
