Let s say you have 25 objects and want one process to handle any one objects click event  You could write 25 delegates or use a loop to handle the click event   public form1         foreach  Panel pl  in Container Components                pl Click    Panel Click           private void Panel Click object sender  EventArgs e           Process the panel clicks here     int index   Panels FindIndex a   gt  a    sender

You can create button in a simple way  such as  Button button   new Button    button Click    new EventHandler button Click    protected void button Click  object sender  EventArgs e        Button button   sender as Button         identify which button was clicked and perform necessary actions    But event probably will not fire  because the element elements must be recreated at every postback or you will lose the event handler  I tried this solution that verify that ViewState is already Generated and recreate elements at every postback  for example  imagine you create your button on an event click      protected void Button Click object sender  EventArgs e               if  Convert ToString ViewState  quot Generated quot        quot true quot                         CreateDynamicElements                          on postback  for example on page load  you should do this      protected void Page Load object sender  EventArgs e                if  Convert ToString ViewState  quot Generated quot        quot true quot                 CreateDynamicElements                     In CreateDynamicElements   you can put all the elements you need  such as your button  This worked very well for me  public void CreateDynamicElements         Button button   new Button        button Click    new EventHandler button Click
