Hi,
Your @Register is wrong here is an example from one of my
projects.
<%@ Register TagPrefix="uc1" TagName="RssViewer" Src="RssViewer.ascx" %>
If drag the control from the solution explorer to the form you
want the control on. VB.net will add the @ register for you.

I have a User Control that I created (.ascx & .ascx.vb file pair) that I am
trying to put in a separate assembly. I know that the User Control works
when it is in the same project and is compiled along with the project it is
used in, so the problem is obviously something I am doing wrong with the
references or something. My current code registers the assembly as:
<%@ Page Language="vb" AutoEventWireup="false"
Codebehind="DatePickerTest.aspx.vb"
Inherits="WebApplication1.DatePickerTest"%>
<%@ Register TagPrefix="NateCtrl" Namespace="NateCtrl" Assembly="NateCtrl"
%>

EnableViewState="False" Text="New Year's 1995"
CausesValidation="False"></asp:button>
</form>
</body>
</HTML>
When I attempt to execute the page, I recieve the following error:
Server Error in '/WebApplication1' Application.

What am I missing here? Thanks.
