如何使用updatepanle 中的gridview中的按钮调用 OnRowCommand事件

[njrc]

一个updatepanle中的gridview中，有一列是button，commandname="sk",gridview 的onrowcommand="sk_rowcom"，
后台定义sk_rowcom事件，判断commandname = "sk"，然后找到index，更新数据库，重新绑定gridview，现在首次绑定可以，点击button，ie报错！初次使用updatepanle,像我这样，如何在updatepanle中调用gridview的后台函数？

麻烦诊断

[hookyzlr]

这里有问题：GridViewRow row = mygrid.Rows[Convert.ToInt32(e.CommandArgument)];
你的<asp:Button ID="Button1" runat="server" Text="编辑" CommandName="skrsupdate" />
并没有设置CommandArgument

怎么设？
