Are you at any point adding the grid to Page's Controls collection? E.g say
you have a PAlceHolder on Page

....
<asp:PlaceHolder ID="PlaceHolder1" runat="server" />
....

After instantiating the grid, add it to the PalceHolder

GridView grid = new GridView();
PlaceHolder1.Controls.Add(grid);

Point is that a control must be in Controls hierarchy of the Page (and its
child controls)in order it to work in any way.
