Re-loading a UserControl after PostBack

[jon]

I'm trying to establish how to replace a usercontrol that has already
been loaded (using LoadControl in the Page.Load event) with a
different UserControl following a PostBack. Tying to call
LoadControl(<newControlName>) after the Page.Load routine has finished
does not appear to work. The only way I can think of doing this is to
call Server.Transfer or Request.Redirect to start a new instance of
the form but this means I loose ViewState for the existing form which
I want to retain.

I need a means of re-firing the Page.Load routine after it has occured
without user ineraction.

Any thoughts greatly appreciated.

Could you load the corresponding user control based upon the value of
Page.IsPostback in the Page.Load?

The Page_Load event is reaided upon every request. This should be an ok location
to recreate any server side controls that were dynamically added from previous
requests. I posted a sample a while ago:

It doesn't use User Controls, but it should work fine.
