select中的onserverchange事件

前台关键代码:

<select runat="server" id="CITY" onserverchange="CITY_ServerChange"  class="select" style="width:60px;"></select>

 

后台关键代码:

 protected void Page_Load(object sender, EventArgs e) {        this.CITY.Attributes.Add("onchange", base.Page.GetPostBackEventReference(this.CITY)); } protected void CITY_ServerChange(object sender, EventArgs e) {        //这是你要写的事件 }
