1、页面代码
<asp:TemplateField HeaderText="等级">
<ItemTemplate>
<asp:Label ID="Label6" runat="server" Text='<%# FormatUserlevel(Eval("User_UserLevel"))%>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
//这个label的作用是为了在后台控制 当你点击编辑按钮的时 DropDownList 的选中值， <asp:Label ID="Label7" runat="server" Text='<%# Eval("User_UserLevel")%>' Visible="false"></asp:Label>
<asp:DropDownList ID="ddl_userLevel" runat="server" >
</asp:DropDownList>
</EditItemTemplate>
</asp:TemplateField>
将此列设为模版，在现实数据的时候是以label形式，当点击控件自带的编辑按钮的时候就是以DropDownList形势显示
2、后台代码
