问题 I have a very basic custom WebViewPage class in which I want to assign a value to a custom property. Here's my code: public abstract class WebViewPage : System.Web.Mvc.WebViewPage { public Employee UserPrincipal { get; set; } public override void Execute() { // Controller is also a custom class that contains the same property which is injected by // a custom ActionFilterAttribute.

问题 I'm having problem with date validation. In my View, I have a jQuery datepicker - I changed the format from yy/mm/dd to mm/dd/yy and now I get client-side validation errors.

问题 In a project I need to set up an ASP.NET MVC (with .NET 4.6.1) but using the "new" EF Core for accessing the database. Unfortunately every documentation explains only how to setup an ASP.NET Core MVC project. I just gave it a try and when it comes to creating the database via the Package Manager Console I get the error message: No parameterless constructor was found on 'DataContext'. Either add a parameterless constructor to 'DataContext' or add an implementation of 'IDbContextFactory' in the

问题 This should replace just the UpdateTarget, but it does not, it replaces the entire page and I don't see why. The correct partial view is being returned, but instead of replacing the target id, it is replacing the entire page. <div id="magHeader"> <p>this is a test.</p> @Ajax.ActionLink("Edit", "GetEditor", "Home", new AjaxOptions(){ UpdateTargetId = "magHeader", InsertionMode = InsertionMode.Replace}) </div> At runtime, the link looks like this: <a href="/Home/GetEditor" data-ajax-update="
