Edited the question for formatting. Are you using any 3rd party pdf conversion library?

Solution 2

Try this

C#

Gridview1.RenderControl(hw);

instead of creating form and adding Gridview to it.

C#

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