Answer 3

Answer 6

<ItemTemplate>文字</ItemTemplate>
<EditTemplate>下拉框 数据源='<%取Items列表的方法()> %'</EditTemplate> 即可.

Answer 7

<asp:TemplateField HeaderText="标识">
<edititemtemplate>
<asp:DropDownList id="ddlEditFlag" runat="server" Font-Size="10pt" Width="65px" __designer:wfdid="w24" SelectedValue='<%# Eval("flag") %>'>
<asp:ListItem Selected="True">未启用</asp:ListItem>
<asp:ListItem>启用</asp:ListItem>
</asp:DropDownList> 
</edititemtemplate>
<itemstyle horizontalalign="Center" width="65px" wrap="False" />
<itemtemplate>
<asp:Label id="lblFlag" runat="server" Text='<%# Bind("flag") %>' Font-Size="11pt" __designer:wfdid="w23"></asp:Label> 
</itemtemplate>
</asp:TemplateField>我使用没有问题。
