Answer 3

可以用代码来实现
也可以用编辑模板。
我感觉用代码自己写方便 
<Columns>
                <asp:BoundField DataField="GRD_ID" HeaderText="序号" InsertVisible="False" ReadOnly="True"
                    SortExpression="GRD_ID" />
                <asp:BoundField DataField="GRD_NAME" HeaderText="年级名" SortExpression="GRD_NAME" />
                <asp:TemplateField HeaderText="部名" SortExpression="GRD_DEPID">
                    <ItemTemplate>
                        <asp:Label ID="Label1" runat="server" Text='<%# Bind("DEP_NAME") %>' Width="121px"></asp:Label>
                    </ItemTemplate>
                    <EditItemTemplate>
                        <asp:DropDownList ID="DEP_DropDownList" DataSourceID="SqlDataSource1" DataTextField="DEP_NAME" DataValueField="DEP_ID" SelectedValue='<%# Bind("DEP_ID") %>' runat="server"></asp:DropDownList>
                    </EditItemTemplate>                
                </asp:TemplateField>
                <asp:CommandField ShowDeleteButton="True" ShowEditButton="True" CancelText="取消" DeleteText="删除" EditText="编辑" UpdateText="更新" />
            </Columns>
