ChildControls disappear after Clicking

[Sandy]

Hi there,

I am developing my own TabControl. So I wrote a property "add", to
create tabs. The TabControl is made of Buttons and inherits the
WebControl Class. And it overrides my CreateChildControls Method.



If I create my Tabs in my base CustomControl Class with Me.add =
"Tab1", everything works fine.

Problem:
When I create my Tabs from ohter contexts, like in CodeBehind the
WebApllication starts normal, but as soon as I click to one of the
Buttons, the complete TabControl disappear.

I want to add my tabs from other contexts.


I'll hope anybody could help me.
