ajax issue

[Guest]

Hi all,

I am having an interesting issue with nested usercontrols with the following
scenario:

Web Project 1
UserControl1 - contains various form controls inside an UpdatePanel
UserControl2 - contains UserControl1

Web Project 1 is then compiled into a dll using the Web Deployment VS2005
plugin

Web Project 2 (references compiled dll of Web Project 1)
Master Page - contains AjaxToolKitScriptManager
UserControlA - contains an UpdatePanel which contains reference to
UserControl1 referenced in compiled dll
Aspx Page - contains details of contentplaceholder for Master Page which
contains UserControlA

Now inside UserControl1 contains a textbox who has a server side value
change event that gets fired which toggles the visibility of some of the
other controls inside UserControl1. When I change the value I can trace the
server side valuechange event being fired. However, the visibility of the
controls dont change at all.

Any ideas?
