asp.net gridview编辑时，下拉框选择上默认的选项
大家好，请教大家一个问题，我是新手。asp.net gridview编辑时，下拉框选择上默认的选项 eg:
<EditItemTemplate>
<asp:DropDownList ID="userDdl" runat="server" Width="100px" >
<asp:ListItem Value="2">普通用户</asp:ListItem>
<asp:ListItem Value="1">核查员</asp:ListItem>
<asp:ListItem Value="0">系统管理员</asp:ListItem>
</asp:DropDownList>
</EditItemTemplate>
在点击编辑的时候，编辑的下拉框选择默认的选项比如：现在是普通用户，然后还有可选的核查员，系统管理员等。
大家帮忙一下，谢谢！ --------------------编程问答-------------------- 前台代码

--------------------编程问答-------------------- 点击编辑的时候获取该行ID 然后绑定下拉框（value值为ID时），不是的话，查一次数据库，然后绑一下就行了 --------------------编程问答-------------------- 谢谢，大家的帮助！ --------------------编程问答-------------------- 学习中 踩踩

cs代码this.dll_Type.SelectedIndex = 0;
