Hi all,

I am using Telerik rad tabs control in my page where I am using its RadTabStrip1_TabClick and OnClientTabSelected both. For one tab I have to use server side code and for others I just need the OnClientTabSelected event and it should not fire the server side code,so my question is that how I restrict the code to reach server side for those tab click where I don't need server side code.

I have used return false but it didn't work;

function onClientTabSelected(sender, args) {
            //set tab value

            var tabText = args.get_tab().get_index();

            var tab = sender.get_selectedTab().get_text();


            if (tab == 'Posts') {

            ShowPostLinks();
        return false;
//stop hitting server side code

            }
            if (tab == "Linkings") {
        return true;
//go to server side
            }
        }
