`<asp:TemplateField HeaderText="id" InsertVisible="False" SortExpression="id"><EditItemTemplate><asp:TextBox ID="Label1" runat="server" Text='<%# Eval("id")%>>`
`</asp:TextBox></EditItemTemplate>`<ItemTemplate>
<ItemStyle Width="20%" />
<asp:Hyperlink ID="sub_topic_id" runat="server"
NavigateUrl='<%# "hohrotherexecview.aspx?id=" + HttpUtility.UrlEncode(Eval("id").ToString())%>'
Text='<%# Eval("id")%>' Target="_self" />`</ItemTemplate>
<asp:TemplateField HeaderText="CLOSED" ItemStyle-HorizontalAlign = "Center">
<ItemTemplate>
<asp:CheckBox ID="ApproveBox" runat="server" />
</ItemTemplate>
</asp:TemplateField>`
当我选择多个ID时,显示错误“找到了具有相同ID的多个控件'sub_topic_id'。FindControl要求控件具有唯一ID。”请帮忙
