我們在修改操作的時候,需要綁定該對象已經有的資訊,那麼怎麼辦呢?
方法一:
this.dropdownlist1.selectedindex = this.dropdownlist1.items.indexof(this.dropdownlist1.items.findbytext("字元串"));
或者
this.dropdownlist1.selectedindex = this.dropdownlist1.items.indexof(this.dropdownlist1.items.findbyvalue("字元串"));
方法二:
在dropdownlist1的databound事件中寫:
dropdownlist1.items.findbyvalue("字元串").selected=true;
dropdownlist1.items.findbytext(“字元串").selected = true;
