Question

在asp.net的cs文件中用隐藏域控件怎样获得DropDownList属性的SelectedValue的值？急用！代码如下：

aspx文件：
<asp:DropDownList ID="hangye" runat="server"></asp:DropDownList>
隐藏域：<input type="hidden" name="hidden1" id="hangye" value="1" runat="server" />
jquery：var zxkTypes = new ZxkPt("<%=this.DropDownList1.ClientID%>","<%=this.DropDownList1.SelectedValue%>");
后台的aspx.cs文件中获取不到SelectedValue的值，应该怎样取？求详细代码！谢谢

Answer 1

<asp:DropDownList ID="hangye" runat="server" Width="100px" AutoPostBack="True"
OnSelectedIndexChanged="ddl_SelectedIndexChanged">
</asp:DropDownList>

protected void ddl_SelectedIndexChanged(object sender, EventArgs e)
{
hangye.value=hangye.SelectedValue;
}

任意位置用 hangye.value 就行了。隐藏域其实没用直接用hangye.SelectedValue 就是了啊
