Hello,

my View.ascx file is setup as follows:

*******************************

<%@ Control language="C#" Inherits="DotNetNuke.Modules.HB_HPImageRotator.View" AutoEventWireup="false"  Codebehind="View.ascx.cs" %>
<%@ Register TagPrefix="mat" TagName="TestUC" Src="~/TestUC.ascx" %>

<asp:PlaceHolder ID="plhld" runat="server">
myPlaceHolder
</asp:PlaceHolder>

******************************* 
the problem is that when I start typing <mat

intellisense won't display the possibility to add TestUC

project setup: I created a module HB_HPImageRotator from the regular dotnetnuke.com template In Visual Studio 2010, I added a WebUserControl to the root of the project TestUC.ascx.

TestUC.ascx:

**************************

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="TestUC.ascx.cs" Inherits="DotNetNuke.Modules.HB_HPImageRotator.TestUC" %>

<asp:Label ID="lblTest" runat="server" Text="My Test Label"></asp:Label>

****************************

TestUC.ascx.cs:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;


namespace DotNetNuke.Modules.HB_HPImageRotator
{
    public partial class TestUC : System.Web.UI.UserControl
    {
        protected void Page_Load(object sender, EventArgs e)
        {


        }
    }
}

***********************

any ideas why the control is not available? If I create a custom web user control under a website project, everything works fine.

if I load the control from code (View.ascx.cs), it works, I mean the Page_Load method gets called..etc. 

TestUC tuc = new TestUC();

but
plhld.Controls.Add(tuc);

won't display the control, although the constructor gets called...

Thx for any insight.
