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?

Using the Default settings of the XamDataGrid, the event should fire when scrolling no matter of the direction. If you have not so many records in the XamDataGrid, you can set the RecordContainerGenerationMode to PreLoad, which will disable the virtualization of the records.

If not, you can also use the RecordsInViewChanged event, which will fire when the records, that are currently in view change - in your scenario very close to InitializeRecord event.

Test these two options and let me know if you still have any problems.

I think I am using the default settings of the grid, what setting would stop the InitializeRecord from firing?

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}">

...

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.

If this is the case, you have to use the following style (option 3 once again)

<Style TargetType="{x:Type igDP:CellValuePresenter}">

                    <Setter Property="BorderBrush" Value="Transparent"/>

                    <Setter Property="BorderHoverBrush" Value="Transparent"/>

                    <Setter Property="ForegroundHoverStyle">

                        <Setter.Value>

                            <Style TargetType="ContentPresenter">

                                <Setter Property="TextElement.Foreground" Value="{Binding Path=Foreground, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type igDP:CellValuePresenter}}}"/>

                            </Style>

                        </Setter.Value>

                    </Setter>

                </Style>

What this "complex" binding does is to bind the Foreground hover color to the Foreground color.

Let me know if you have any questions on this.

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?

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