aspx and ascx

Hi there

I am trying to write some "web user controls" which I want to include on an
aspx.

In my VS2005 solution I have a project with my aspx, and another project
with my user controls (ascxs). But I can't compile my solution because the
aspx complains that it can see the ascxs. I get an error like:

Element 'MyControl' is not a known element. This can occur if there is a
compilation error in the Web site.
File 'MyControl.ascx' was not found.

Do the ascxs have to sit in the same project as the aspx?

My aspx looks like this:

<%@ Register TagPrefix="uc" TagName="MyControl" Src="MyControl.ascx" %>

<%@ Page Language="C#" AutoEventWireup="true"
CodeBehind="ControlTest.aspx.cs"
Inherits="alphasolutions.web.control.test.ControlTest" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Test Input</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <uc:MyControl id="a_control" runat="server" />
    </div>
    </form>
</body>
</html>

Thanks,
Peter

I'm pretty sure I read somewhere that ascx's are not "real" re-useable, but
only copy/paste re-useable.
So my answer would be yes, they do need to be in the same project.

Yes, they need to be in the same project. This is the only supported way to
do it, although I've heard of unsupported techniques such as using shared
virtual directories for the user controls.
For high quality reusability you should create custom controls, not user
controls.

Great, thanks for the info. I think I'll stick with the user-controls for
the moment, and live with the "restriction".

Thanks,
Peter
