Clear log Event log:

  • Client-Side Events

    RadSlidingZone client-side events:
    • OnClientLoad - raised when the initialization of the RadSlidingZone is complete.
    RadSlidingPane client-side events:
    • OnClientCollapsing - raised before the RadPane is collapsed.
    • OnClientCollapsed - raised when the RadPane is collapsed.
    • OnClientExpanding - raised before the RadPane is expanded.
    • OnClientExpanded - raised when the RadPane is expanded.
    • OnClientResizing - raised before the RadPane is resized.
    • OnClientResized - raised when the RadPane is resized.
    • OnClientDocking - raised before the RadPane is docked.
    • OnClientDocked - raised when the RadPane is docked.
    • OnClientUndocking - raised before the RadPane is undocked.
    • OnClientUndocked - raised when the RadPane is undocked.

    All client side events take two parameters - sender and arguments:
            function OnClientLoad(sender, args) 
            {
                //sender represents the slidingZone that has fired the event
            //the code below obtains the id of the slidingZone that has fired the event
            var id = sender.get_id();
             }

    All events that end in "ing" (i.e. OnClientResizing)" can be cancelled. To do this you should call the set_cancel(true) method in the event handler: 

             function OnClientResizing(sender, args)
             {                            
	    set_cancel(true);                  
         }
    Once, the OnClientResizing event is cancelled, the slidingPane cannot change its width and height.
