Capture (handling) return event
1. Implement the iPostBackeVentHandler interface (allowing controls to raise events on the server to respond to retrace from the client. 2. Implement the RaisePostBackeVent method to raise an event. Example: public void RaisePostBacked (String Eventargument) {onclick (evenetargs.empty);}
Note: Like the control of the return data to the IPostBackDataHandler interface, the rendering logic must also provide the Name feature of the control for the reward of the return event to the replenishment of the return event to the control.
