I have a ajaxToolkit:CollapsiblePanelExtender along with two asp:UpdatePanels it controls (one panel expands the other panel when clicked).
Works great until I do an AJAX update from a Timer that kicks off. The page updates…and the CollapsiblePanelExtender collapses 😛
Anyone know how to get this control to maintain the state of the panel it’s expanding?
I remember running into this exact problem.
CollapsiblePanelExtender has a property, ClientState, that doesn’t seem to get tracked and maintained in ViewState.
You should be able to manually track and maintain the value in a HiddenField (or ViewState or Session, if you like) and restore the CPE.ClientState to that value upon the AJAX update.
UPDATE
Found a resource that suggests that you simply need to set both Collapsed and ClientState properties.
