I use two different collapsiblepanelExtenders with similar colapsedControlID which is not a matter here. Since both of them working but with some misbehaviour, for example if the first one is open and I click wherever on it , the second one extends. also by clicking on the second one it collapses.
That means that some how an event triggers and makes them collapse or extend.
I have a kind of editing panel inside each extandedPanel which are used to update something on the page. the problem is that by clicking on each textbox or fileupload, the second panel collapses again. before any other action. So that I can not enter the textboxes. I can do that if I use tab button on keyboard. but that sucks really.
<asp:Panel ID="OIOuterPanel" runat="server">
<asp:panel id="ExtPnl_orgInfo" runat="server" >
<asp:Panel id="ColPnl_orgInfo" runat="server" >
<asp:panel id="OIOuterPanelExt" runat="server" >
<asp:CollapsiblePanelExtender ID="OICPEOuer" runat="server" TargetControlID="OIOuterPanelExt"
