我想在一页中使用2个Gridview
第一个gridview应显示在页面加载上，第二个应显示在每行第一个gridview内点击链接按钮
设计中的第一个gridview

答案 0 :(得分：0)
Change the LinkButton details as below
<asp:LinkButton ID="LinkButton1" runat="server" CommandName="bind" CommandArgument = "<%#Eval("Class_id") %>" Text='<%#Eval("Class_id") %>'> </asp:LinkButton>
并在代码中
protected void gvDetails_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "bind")
{
Loaddata1();
}
}
希望这个帮助
