Adding a WebControl to a WebControl

[Steven]

Hi

I have created a Web Control that inherits from CompositeControl. I can add
ASP.NET controls into this no problem but if I try to add another WebControl
to the CompositeContol I get the old "Object reference not set to an instance
of an object." problem. I also get this problem when attempting to add
RadControls. Any Idea's please?

Regards
Steven.

Actually, What I added below is wrong. I only have a problem adding
RadControls. Possibly something to do with registering the assemblies in the
control but I am not sure.
