I'm trying to use an Atlas UpdatePanel to just update a label when a text
box has changed. The problem is that my textbox is in a user control and
I'm using Master Pages - with the combination of these two things, the page
flashes everytime my textbox changes and the panel is updated.
If I just use a regular textbox along with the Master Page, it works fine.
If I use by user control without the Master Pages, it works fine. When I
combine them....flash.
I've pasted in the simplest example I could make. Any help would be much
appreciated as this has been very frustrating!
Thanks,
Diane Y.
