How to hide a column in Gridview?

If set visible to false in Gridview template, this column will not be rendered into html.  

<asp:BoundField DataField="ID" HeaderStyle-Width="0px" Visible="false" />

 Should add onrowdatabound event handler to do that:

<asp:GridView ID="GridView1" runat="server" onrowdatabound="GridView1_RowDataBound">

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)

{

    if (e.Row.RowType != DataControlRowType.DataRow) return;

    e.Row.Cells[1].Visible = false;

}
