Coming back on the text color I'm still having problems.

I need to set the text color of each row depending on a color supplied at run time by a field in the datasource. The color is set by the end user and can be anything. I have managed to get half way there using this code

private Style s;
private Style s2;
private Setter se;
private Setter se2;
private void xamDataGrid1_InitializeRecord(object sender, Infragistics.Windows.DataPresenter.Events.InitializeRecordEventArgs e)
{
    //e.Record.DataPresenter.Background = Brushes.Red;
    DataRecord dr = e.Record as DataRecord;

    if (dr != null)
    {
        if (((string)dr.Cells[5].Value).Trim() == "MR")
        {
            s = new Style();
            se = new Setter();
            se.Property = CellValuePresenter.ForegroundProperty;
            se.Value = Brushes.Red;
            s.Setters.Add(se);
            dr.Cells[5].Field.Settings.CellValuePresenterStyle = s;
        }
        else
        {
            s2 = new Style();
            se2 = new Setter();
            se2.Property = CellValuePresenter.ForegroundProperty;
            se2.Value = Brushes.Aquamarine;
            s2.Setters.Add(se2);
            dr.Cells[5].Field.Settings.CellValuePresenterStyle = s2;
        }
    }
}

This kinda works when you scroll down the list but when you scroll back the event is no longer fired (I guess because of virtual loading) but all the items are re-rendered in aquamarine.

Any ideas please?

Alan,

Looking at the situation now, it looks much more simpler. Iteraring through the records and creating and assigning styles for all them and their cells is quite cumbersome and leads to some problems that you have experienced. The events like InitializeRecord, RecordInViewChanged, etc. are used rather to make changes in the Data than change their visual appearance, because thei presenters are not yet created. Virtualization techniques of the XamDataGrid makes this task even more difficult, however not impossible.

Please find the attached project that I created with the best 3 ways that I came up with for achieving this task. The WPF Framework and its binding engine are pretty "smart" in your scenario and binding to the Color cell's string value would be just enough for the foreground to change. Also,using converters will have the same desired effect. The third way changes this dynamically, as your approach, but slightly different.   

Please let me know if you have further questions on this.

Cheers!

Hello Alex,

I've made a litte modification in your sample. I've set the theme="Onyx" in the XamDataGrid and it does not show the orange color when the mouse hovers the records. The background appear in grey color (my window configuration?). How can I preserve the Onyx theme and change the foreground of the cell at the same time?

Thank you very much.

I'm sorry. I've forgotten saying this effect occurs in Option 3 CellValuePresenter.

Just to make sure I am on the right track, when you hover over the cell, you want the color of the text (Red,Green) not to change, right?

No. The color of the text is a second effect.

What I mean is that Onyxs theme, when you move the mouse over the records, shows the row in orange .

DataRecordCellArea.BackGroundHover is grey and it should be the Onyx color.

Thanks for clearing that out. You have to "inherit" the style for the DataRecordCellArea from the one of the theme like this:

namespace for themes: xmlns:Themes="http://infragistics.com/Themes"

...

<Style TargetType="{x:Type igDP:DataRecordCellArea}" BasedOn="{x:Static Themes:DataPresenterOnyx.DataRecordCellArea}">

...
