For sorting you have to bind the grid...

C#

private void LoadGrid(string sortExpr, string sortDirection)
{


        DataSet ds = new DataSet();
        SqlDataAdapter SqlDA = new SqlDataAdapter("Select * from tablename order by "+sortExpr+"  "+sortDirection+"", connectionString);
        SqlDA.Fill(ds);
        if (ds != null)
        {
            gdManageForm.DataSource = ds;
    gdManageForm.EditIndex = -1;
    gdManageForm.DataBind();
        }

}

protected void gdManageForm_Sorting(object sender, GridViewSortEventArgs e)
{
    string sortExpression = e.SortExpression;
    ViewState["SortExpression"] = sortExpression;
    if (GridViewSortDirection == SortDirection.Ascending)
    {
        GridViewSortDirection = SortDirection.Descending;
        SortGridView(sortExpression, DESCENDING);
    }
    else
    {
        GridViewSortDirection = SortDirection.Ascending;
        SortGridView(sortExpression, ASCENDING);
    }
}

private void SortGridView(string sortExpression, string direction)
{
    //If it is default state
    LoadGrid(sortExpression, direction);
}

private SortDirection GridViewSortDirection
{
    get
    {
        if (ViewState["sortDirection"] == null)
            ViewState["sortDirection"] = SortDirection.Ascending;
        return (SortDirection)ViewState["sortDirection"];
    }
    set { ViewState["sortDirection"] = value; }
}
