使用链接按钮或任何按钮，但你必须传递如下所示的命令参数

use link button or any button but you have to pass command argument like written below

<asp:linkbutton id="LinkButton1" runat="server" causesvalidation="False" commandname="Edit" commandargument="<%# Container.DataItemIndex %>" xmlns:asp="#unknown"> </asp:linkbutton> 

after that you can get Rowindex from code behind like this

int RowIndex = Convert.ToInt32(e.CommandArgument.ToString());
