Assembly: System.Web.Mvc (in System.Web.Mvc.dll)

The following example shows how to render views that do not have a matching ActionResult method. For example, if you have a Details.aspx view but no corresponding method exists that returns an ActionResult instance, the following example displays the Details view when a request to for the Details action is made on the controller. If there is no matching view, the error page displays a message. This example shows one way to use the HandleUnknownAction method. Action methods are not required to return an ActionResult object.
protected override void HandleUnknownAction(string actionName) { try { this.View(actionName).ExecuteResult(this.ControllerContext); } catch (InvalidOperationException ieox ) { ViewData["error"] = "Unknown Action: \"" + Server.HtmlEncode(actionName) + "\""; ViewData["exMessage"] = ieox.Message; this.View("Error").ExecuteResult(this.ControllerContext); } }
