The ordering of GridView has a lot of problems, a solution that can work is this one:

Add the sort event in GridView

<asp:GridView ... OnSorting="gridView1_Sorting" AllowSorting="true">

And in your CodeBehind

private string ConverterSortDirection(SortDirection sortDirection)
{
    string novaDirecao = String.Empty;

    switch (sortDirection)
    {
        case SortDirection.Ascending:
            novaDirecao = "ASC";
            break;
        case SortDirection.Descending:
            novaDirecao = "DESC";
            break;
    }
    return novaDirecao;
}


protected void gridView1_Sorting(object sender, GridViewSortEventArgs e)
{
    DataTable dataTable = gridView1.DataSource as DataTable;

    if (dataTable != null)
    {
        DataView dataView = new DataView(dataTable);
        dataView.Sort = e.SortExpression + " " + ConverterSortDirection(e.SortDirection);

        gridView1.DataSource = dataView;
        gridView1.DataBind();
    }
}
