  Exception with Html.RenderUserControl()

  Mar 19, 2008 05:05 PM|LINK

   Hi All,

   This week I thought I'd take a look at the Preview 2 of the ASP.NET MVC. Until this very moment I am quite impressed with its capabilities although i stumble across a small problem.

  I am receiving an error when I execute the method below :

  <% =Html.RenderUserControl("~/Views/Home/UserControls/HoofdMenu.ascx", ViewData["Menus"]) %>

  Ofcourse, I first searched Google  for an explanation, but i just cant seem to put it all in the right context, i cant figure out what is happening here.

  Anyone have any ideas or insight into this behaviour?

   

  The error states :

   "Error executing child request for handler 'System.Web.Mvc.ViewPage'."

  Not certain based on that exception info, but I have seen some pretty weird and wonderful expceptions when my pages struggle to compile.
  Check the <%@ directive at the top of the control and make sure it correctly references its Inherits and Codebehind.

  Just a thought, can't promise it will help in this case.

  My recommendation is to use the old declarative way of referencing a user control to debug

  at the top of your aspx page

  <%@ Register src="~/Views/Home/UserControls/HoofdMenu.ascx" tagname="HoofdMenu" tagprefix="uc1" %>
  
   in your code:

   <uc1:HoofdMenu ID="HoofdMenu1" runat="server" />

   

  this way the error will occur in your page with trace and you can debug.

  I personally like the nomenclature of RenderControl and hope the asp.net mvc team evolves this a bit.
