You can hide the column by visible property

and during refresh page you can call it as True

C#

GridView1.Columns[1].Visible=true;

and you can put loop for visible true or false

C#

foreach (GridViewRow gvr in gv.Rows)
       {
           //here specify cell you want to hide
           //also you may put any conditions
           gvr.Cells[0].Visible = false; // Hide cell
       }

In Page load what Gridview columns you want just set visible true remaining are set to false.In Button Click Set visible true to all columns .
in Design mode declare a gridview like
<asp:gridview id="GridView1" runat="server" autogeneratecolumns="false" xmlns:asp="#unknown">
<columns> <asp:boundfield accessibleheadertext="ID" datafield="ID" headertext="ID">
<asp:boundfield accessibleheadertext="NAME" datafield="NAME" headertext="NAME">
<asp:boundfield accessibleheadertext="ADDRESS" datafield="ADDRESS" headertext="ADDRESS">
<asp:boundfield accessibleheadertext="PHONE" datafield="PHONE" headertext="PHONE">

in csfile:

protected void Page_Load(object sender, EventArgs e)
{
DataTable dt = new DataTable();
if (dt.Columns.Count == 0)
{
dt.Columns.Add("ID");
dt.Columns.Add("NAME");
dt.Columns.Add("ADDRESS");
dt.Columns.Add("PHONE");
}
DataRow dr;
for (int i = 0; i < 10; i++)
{
dr = dt.NewRow();
dr["ID"] = "ID" + i;
dr["NAME"] = "NAME" + i;
dr["ADDRESS"] = "ADDRESS" + i;
dr["PHONE"] = "PHONE" + i;
dt.Rows.Add(dr);
}
GridView1.DataSource = dt;
GridView1.DataBind();

GridView1.Columns[3].Visible = false;

}
protected void Button1_Click(object sender, EventArgs e)
{
if (GridView1.Columns.Count > 0)
{
GridView1.Columns[3].Visible = true ;

}
}
