推荐答案

只是尝试将代码中的选择更改方法从 DropDownList1_SelectedIndexChanged 重命名为 ddlprocess_SelectedIndexChanged up on OnSelectedIndexChanged =ddlprocess_SelectedIndexChanged>



希望这有助于

just try to rename your selection change method in code behind from DropDownList1_SelectedIndexChanged to ddlprocess_SelectedIndexChanged also the mark up as OnSelectedIndexChanged="ddlprocess_SelectedIndexChanged">

Hope this helps

将.aspx文件中DropDownList1的AutoPostBack属性设置为true

AutoPostBack =True

set AutoPostBack property to true of DropDownList1 in .aspx file
AutoPostBack="True"
