推荐答案

您好，

我看到您有2个gridviews，但是我看不到为任何一个网格指定的任何数据键名称.

应该是这样的，

Hi,

I see you have 2 gridviews but i dont see any datakey name specified for either of the grids.

this should be something like,

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 
DataKeyNames="Sqnce_id">

检查此用法以获取更多信息.
希望这会有所帮助.

祝您编码愉快！
