1.
onrowcommand="GridView1_RowCommand1"
在gridview申明时的属性里要有，然后找到闪电，双击
还有要把那个按钮行模板化，就是箭头里面的templed啥的，我懒得去看啦
2.在gridview包含<column>里的该命令行的要有
<asp:TemplateField ShowHeader="False">
<ItemTemplate>
<asp:Button ID="Button2" runat="server" CausesValidation="false"
CommandName="look" Text="查看" CommandArgument='<%#Eval("ep_id")%>' />
</ItemTemplate>
</asp:TemplateField>
3.在这个事件里，加入
if (e.CommandName == "look")
{
Session["gridview1id"] = Convert.ToInt32(e.CommandArgument.ToString());
}
else if (e.CommandName == "exam")
{
int id_in = Convert.ToInt32(e.CommandArgument.ToString()); }
就差不多啦
