Hi, I have about 6 update panels, each containing multiple collapsible panels. In one of the update panels i have a button and treeview; when the button is clicked, a child node is added to the treeview (this works), however, the entire page flickers (looks like a refresh) when the button is clicked. I have placed a label inside the update panel and another outside it, both of which contain the value of DateTime.Now.ToLongTimeString() on page load; only the lable inside the update panel changes time, so to me that is indicative that only the correct panel is posting back to the server, but why then does the page still flicker ? And how do i fix it?
Even when removing the functionality to add tree nodes, just clicking the button causes the page to refresh (flicker).

I am also having this issue
I have a collapsiblepanel inside an update panel with update set to conditional and have set the triggers. when i select an item from a drop down from inside the updatepanel the page retrieves the data and flickers...however if i block out the update panel extender no flicker.....
I have set the update panel to postback enable to false etc
not sure of this issue ..is this a bug?
Any more one this ? anyone?
As there was an urgent release required where the client wanted this feature with ajax ..i ended up creating a client javascript version...
I am having the same problem. Did anyone find any solution to this ?
