OnClientUndocking

The OnClientUndocking client-side event handler is called when a sliding pane is about to be undocked. The event can occur because the user clicks on the undock button, or as the result of a a call to a client-side method.

note

The OnClientUndocking event is supported by RadSlidingPane . It takes the place of the depricated OnClientBeforeUndock event.

The following two parameters are passed to the event handler:

  • sender is the pane that is about to be undocked.
  • eventArgs has the following methods:
    • set_cancel() lets you prevent the pane from being undocked.
    • get_cancel() returns whether the operation was cancelled.

The following example uses the OnClientUndocking event to show a confirmation dialog:

<script type="text/javascript">
    function confirmUndock(sender, eventArgs) {
        eventArgs.set_cancel(!confirm("Are you sure you want to undock " + sender.get_title() + "?"));
    }
</script>
