推荐答案

hi，



查看你的cs页面下拉列表中包含DropDownList1_SelectedIndexChanged事件。你在设计页面中提到过。如果您想激活此事件，请在您的cs文件中创建此事件，或从设计编码中删除以下行。



onselectedindexchanged =DropDownList1_SelectedIndexChanged





问候，

check your cs page having "DropDownList1_SelectedIndexChanged" event for dropdown. you have mentioned in design page. If you want fire this event create this event in your cs file or remove the following line from your design coding.

onselectedindexchanged="DropDownList1_SelectedIndexChanged"
