由于需要我对gridview进行了动态绑定（用代码）发现当绑定列使用boundfield时，gridview运行正常；
当绑定列使用templatefield时，gridview在编辑状态下无法更新，但编辑，取消都没有问题。
（使用templatefield是为了添加dropdownlist）后加断点发现，无论点更新或取消都会触发RowCancelingEdit事件，而不会触发rowupating事件。查了csdn的一些方法，都没解决问题。求助啊！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！

<EditItemTemplate>
<asp:DropDownList ID="ddlRight" runat="server">
<asp:ListItem>主持</asp:ListItem>
<asp:ListItem>出席</asp:ListItem>
</asp:DropDownList>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="labRight" runat="server" Text='<%# Bind("UserRight") %>' />
</ItemTemplate>
</asp:TemplateField>
后台用((DropDownList)this.gvUsers.Rows[e.RowIndex].Cells[x].Controls[x]).SelectedValue获取updating成功和canceling事件都要写gridview.EditIndex=-1

现在的问题是根本不会触发updating事件我updating和canceling都没加代码，我只测试触发那个事件触发都错了，写了也白写，另外我看了下gridview的事件也没丢失。感觉问题应该在template类里，可是网上的template类例子大多都这么写的啊！
