Collapsible Panel Get State

I am trying to check the state of a panel with collapsible panel extender.

I want to know on client side know whether it is expanded or collapsed.

Pretty much as simple as that. Anyone got any ideas?

Solution 
  • function SomethingThatNeedsToKnowTheStateOfThePanel(){
    var extender = $find("<%= thePanelExtender.ClientID %>");
    if(extender.get_Collapsed()){
        // panel collapsed
    } else {
        // panel not collapsed
    }
}

    Assuming that thePanelExtender is the extender control. You can also change the collapsed state using set_Collapsed(true|false)
