Answer 1

你这个是编辑状态下的  而你的删除应该不是在编辑状态下的 你可以加一个隐藏域hidden到  <ItemTemplate> 里面然后再操作

Answer 2

<EditItemTemplate>
                                       <asp:Label ID='TBPTY' Text='<%#Eval("ConName")%>' runat='server'/>
                                          </EditItemTemplate>========》<ItemTemplate>
                                       <asp:Label ID='TBPTY' Text='<%#Eval("ConName")%>' runat='server'/>
                                         <ItemTemplate>
