WPF DataGrid Row-level styling

It took me a very long time to figure out how to do this. The following code takes a WPF (and probably silverlight) datagrid and changes the row foreground color based on a single property in that row.

<DataGrid AutoGenerateColumns="True"  Name="dgProjects" >

    <DataGrid.RowStyle>
                <Style TargetType="DataGridRow">
                    <Style.Triggers>
                        <DataTrigger Binding="{Binding Path=HasProblems}" Value="True">
                            <Setter Property="Foreground" Value="Red"/>
                        DataTrigger>
                    Style.Triggers>
                   
                Style>
            DataGrid.RowStyle>
DataGrid>
