RadTabStrip for ASP.NET AJAX Version Q3 2008 released 11/25/2008 (release history)

RadTabStrip provides a number of client-side events that would allow you to accomplish even the most complicated tasks.

You can attach to the RadTabStrip's events by using either the server-side properties or the client-side API.

1. Attaching event handlers via a server-side property
   Each client-side event has a corresponding property, whose name is formed like OnClient[EventName].
   You can set the property to the name of the function to be called when the event occurs.

   <telerik:RadTabStrip ID="RadTabStrip1" runat="server" OnClientTabSelected="onTabSelected">
   </telerik:RadTabStrip>
   
   <script type="text/javascript" >
      function onTabSelected(sender, args)
      {
          	alert("Selected: " + args.get_tab().get_text());
      }
   </script>
   
   		

2. Using the client-side API to attach event handlers
   Using the client-side API of RadTabStrip allows you to attach multiple event handlers to one event using the standard MS AJAX conventions.

   <script type="text/javascript">
   	function onTabSelectedHandler1()
   	{
   		alert("First handler called");
   	}
   	function onTabSelectedHandler2()
   	{
   		alert("Second handler called");
   	}
   
   	function pageLoad()
   	{
   		var tabStrip = $find("<%=RadTabStrip1.ClientID%>");
   		
   		tabStrip.add_tabSelected(onTabSelectedHandler1);
   		tabStrip.add_tabSelected(onTabSelectedHandler2);
   	}
   </script>
   

   Another advantage of the client-side API is the possiblity of dynamically detaching certain handlers. You can use the remove_tabSelected method of the tabstrip object.
   
   

   <script type="text/javascript">
   	$find(<%=RadTabStrip1.ClientID%>).remove_tabSelected(onTabSelectedHandler1);
   </script>
   

3. Cancelling an event
   The events, whose names end in ing, can be cancelled. You can cancel the event by using the set_cancel method of the event arguments passed to the handler.

   <script type="text/javascript">
   	function onClientTabSelecting(sender, eventArgs)
   	{
   	    eventArgs.set_cancel(true);
   	}
   </script>
