I have one sidebarview ,on that i have added one textbutton("exit"), i want when i click that button , we directly return to dock.Please anyone suggest me how to do that.

Try something like this:

CODE

this.controls.exampleBtn = new KONtx.control.TextButton({
  events : {
    onSelect : function(event) {
       KONtx.HostEventManager.send("exitToDock");    
    }
  }  
});
