repeater DropDownList 事件

类型一：

protected void selChengji_OnSelectedIndexChanged(object sender, EventArgs e)
{
      DropDownList drop = sender as DropDownList; //获取当前选中的DropDownList
         Repeater repS = drop.Parent.Parent as Repeater; //drop的上一级的上一级控件就是Repeater控件
        int n = ((RepeaterItem)drop.Parent).ItemIndex; //获取当前选中行的索引
           //获取其他信息进行操作
         HtmlInputText xuefen = (HtmlInputText)(repS.Items[n].FindControl("txtXuefen"));
        string id = ((HtmlInputHidden)(repS.Items[n].FindControl("txtId"))).Value;
           
     }

类型二：

<asp:DropDownList AutoPostBack="true" OnSelectedIndexChanged='ChangeOrderStatu' ToolTip='<%# Eval("OrderId") %>' runat="server" ID="drdlstOrderStatuList"></asp:DropDownList>

protected void ChangeOrderStatu(object sender, EventArgs e)
    {
        DropDownList drop = sender as DropDownList;
        int orderId = int.Parse(drop.ToolTip);
        int isPay = int.Parse(drop.SelectedValue);
