推荐答案

页面是下拉列表选择的回滚页面
设置 AutoPostBack属性 [

page is postback when dropdown list seleceted
Set AutoPostBack property[^] of dropdown as ''False''

After making the change, Selected change event will fire only when control goes to server.

您可以使用 [

You can use Update panel.[^] and wrap the drop down list in update panel if you want to submit data to server but do not want to reload the page.
