could you give me an example of using the RecordsInViewChanged event in this context please? I can't seem to make this work.

Actually a further update. I have now also noticed that all cells in a column are re-rendered when you horizontally scroll them out of and back into view so that means you would possibly have to handle 3 events just to maintain the state of your grid! Also the conditional rendering of different cells in different text colors is inaccurate and therefore unuseable in any case. I achieved what I am trying to do in the last version of our product with a VB6 listview with no difficulty.

Having spent many hours and searching your forum it seems that many people have had this problem but there doesn't seem to be a solution. I can't really waste much more time on this but I'll give it one more go before giving up. If this problem can be solved I will definitely buy the tools.

Firstly here is a code snippet showing how the process is run. I realise that this is probably not the most efficient way to do it as all visible records are re-evaluated each time the event fires but I haven't figured out the proper way to use the RecordsInViewChanged event. This method however should be re-rendering the visible rows every time this event is fired.

private void xamDataGrid1_RecordsInViewChanged(object sender, Infragistics.Windows.DataPresenter.Events.RecordsInViewChangedEventArgs e)
{          
    if (e.Source != null)
    {
        Record[] drc = xamDataGrid1.GetRecordsInView(false);
        foreach (Record r in drc)
        {                   
            DataRecord dr = r as DataRecord;
            if (dr != null)
            {
                if (((string)dr.Cells[5].Value).Trim() == "MR")
                {
                    Style sRed = new Style();
                    Setter seRed = new Setter();
                    seRed.Property = CellValuePresenter.ForegroundProperty;
                    seRed.Value = Brushes.Red;
                    sRed.Setters.Add(seRed);
                    dr.Cells[5].Field.Settings.CellValuePresenterStyle = sRed;
                    dr.Cells[4].Value = "RED";
                }
                else
                {
                    Style sGreen = new Style();
                    Setter seGreen = new Setter();
                    seGreen.Property = CellValuePresenter.ForegroundProperty;
                    seGreen.Value = Brushes.Green;
                    sGreen.Setters.Add(seGreen);
                    dr.Cells[5].Field.Settings.CellValuePresenterStyle = sGreen;
                    dr.Cells[4].Value = "GREEN";
                }
               
            }
        }
    }
}

Below is a screen shot of a portion of the grid when initally loaded but not scrolled. All text is rendered black but the MR & MRS column should be colored the same as the description in the previous column.

The state remains the same if the scroll bar is dragged (ie RecordsInViewChanged event doesn't fire)
