hi with the help of event bubbling child control is propagating event up its containment hierarchy. mostly it used in data bound control like datalist gridview Repeater.... here event is automatically bubbled up to its parent. Please refer link for creating bulling event http://msdn.microsoft.com/en-us/library/aa719644(v=vs.71).aspx In Tunneling Event routed event is travels prom parent control to last child controls.
