Nested UpdatePanel + Tabs + Editor
Hi guys,
Sorry I haven't replied the other threads, I was involved in other parts of the project.
I was testing one scenario where I've got a Nested UpdatePanel. In fact, the second UpdatePanel is inside a User Control, but I am making it simple and put everything in one page.
It works fine when the main UpdatePanel is set to UpdateMode="Always", but it is exactly what I am trying to avoid, once I just need to refresh the content inside the tab where my UC is placed.
I am not sure the problem is because it is in a Nested UpdatePanel or is something I am doing wrong, but I'll use a similar sample I posted before, just to keep the sample as similar as possible of my real situation.
The sample uses a Datasource already sent here:
http://forums.ext.net/showthread.php?postid=682.aspx
Any help would be very appreciated.
Leo.
