试试这个

Try this

Gridview1.RenderControl(hw);

而不是创建表单并向其中添加Gridview.

instead of creating form and adding Gridview to it.

HtmlForm frm = new HtmlForm();
       Gridview1.Parent.Controls.Add(frm);
       frm.Attributes["runat"] = "server";
       frm.Controls.Add(Gridview1);
       frm.RenderControl(hw);
