Logic is .. If you have one or more update panel in the same page then properties of all update panel should be same such as if update panel data are dependency on each other
Update Mode : Always
EnableViewState : true(if you are using it)
Or you can explicitly update the Update panel when mode is conditional
Let us say you have two update panel like up1 and up2.
You have placed the label in the up1 and the other form or button placed in the up2.
Now on the click event in the up2, label placed in the up1 should be updated without loading the full page. Set the following stuffs
Set EnableParitialRendering ='True'(Script Manager)
Set Update Mode :Conditional(up1)
Set Update Mode : Always (up2). All set up done here. On click of a button in the up2, do your work and call up1.Update(); That's all.
