GridDataControl Background row

Hello,

I have implemented this code to set Background row in function of a row value:

void Model_QueryCellInfo(object sender, GridQueryCellInfoEventArgs e)
{
if (e.Cell.RowIndex > 0 && e.Cell.RowIndex < model.RowCount - Grid.TableSummaryRows.Count)
{
DataRow Fila = null;
Fila = ((DataRowView)model.Table.GetRecordFromRow(e.Cell.RowIndex)).Row;

if ((int)Fila["Value"] == 1)
{
e.Style.Background = Brushes.LightCoral;
}
else if ((int)Fila["Value"] == 2)
{
e.Style.Background = Brushes.LightCyan;
}
}
}

But, this doesn't work when there are grouping columns. How to modify the code to do that code works with grouping columns too?

Thanks.
