Is there any good reason to use FormCollection instead of ViewModel? No. I have following issues. Issue – 1 In case FormCollection is being used…It will be mandatory to Type Cast the Primitive Type Values un-necessarily because while getting the entry of specific Index of the System.Collections.Specialized.NameValueCollection, value being returned is of type String. This … Read more
Edit: Here is a blog post on this topic as well: How to Detect Errors of Our ASP.NET MVC Views on Compile Time To make your views to be compiled, do the following; Unload your project by right clicking the project on the solution explorer in VS and clicking unload project right click the project … Read more
What is the best practice on where the logic for the @foreach should be at? Nowhere, just get rid of it. You could use editor or display templates. So for example: @foreach (var item in Model.Foos) { <div>@item.Bar</div> } could perfectly fine be replaced by a display template: @Html.DisplayFor(x => x.Foos) and then you will … Read more
ViewData/ViewBag – valid only for the duration of the current request. You set it in a controller action and use it in the view, then it disappears. The difference is that the first is a dictionary whereas the second is just a dynamic wrapper around this dictionary. Both point to the same data though. ViewBag … Read more
The route name is not stored in the route unfortunately. It is just used internally in MVC as a key in a collection. I think this is something you can still use when creating links with HtmlHelper.RouteLink for example (maybe somewhere else too, no idea). Anyway, I needed that too and here is what I … Read more
I’ll broadly agree with Vagrant on the cause: your action was executing, writing markup to response stream the stream was unbuffered forcing the response headers to get written before the markup writing could begin. Your view encountered a runtime error Exception handler kicks in trying to set the status code to something else non-200 Fails … Read more
You can override the message by supplying the data-val-number attribute yourself when rendering the field. This overrides the default message. This works at least with MVC 4. @Html.EditorFor(model => model.MyNumberField, new { data_val_number=”Supply an integer, dude!” }) Remember that you have to use underscore in the attribute name for Razor to accept your attribute.
Content-type You don’t need to specify that content-type on calls to MVC controller actions. The special “application/json; charset=utf-8” content-type is only necessary when calling ASP.NET AJAX “ScriptServices” and page methods. jQuery’s default contentType of “application/x-www-form-urlencoded” is appropriate for requesting an MVC controller action. More about that content-type here: JSON Hijacking and How ASP.NET AJAX 1.0 … Read more
You could make your own ControllerFactory and DummyTempDataProvider. Something like this: public class NoSessionControllerFactory : DefaultControllerFactory { protected override IController GetControllerInstance(Type controllerType) { var controller = base.GetControllerInstance(controllerType); ((Controller) controller).TempDataProvider = new DummyTempDataProvider(); return controller; } } public class DummyTempDataProvider : ITempDataProvider { public IDictionary<string, object> LoadTempData(ControllerContext controllerContext) { return new Dictionary<string, object>(); } public void … Read more
Adding a class to Html.EditorFor doesn’t make sense as inside its template you could have many different tags. So you need to assign the class inside the editor template: @Html.EditorFor(x => x.Created) and in the custom template: <div> @Html.TextBoxForModel(x => x.Created, new { @class = “date” }) </div>
