Move from my Netease blog ..... A server control button is added to Itemtemplate in ListView. After rendering by the server. It is difficult to obtain the ID of the button. Therefore, ID data is bound to the button in ItemDataBound. Btn. attributes ["MyId"] = btn. clientID; btn. attributes ["onclick"] = "check (" + slid + ", this);"; // an onclick event is bound. this can also be used as the ID of the current btn.
