Hi Sathish,

You can cancel the PostBack by using args.set_cancel(true) method as shown below.

JavaScript:

<script type="text/javascript">
function OnClientTabSelecting(sender,args)
{
    var result = MyFunction(); // Call the function
    if(!result)
    {
        args.set_cancel(true);
    }
}
</script>

Thanks,
Shinu.
