WPF Foreground Color in a DataGrid, Change via Code (C#)?

Question

Hi,
I need to Change a Foreground Color in a DataGrid Line, here ist the XAML Code from the Line in the DataGrid:

                   <DataGridTemplateColumn Header="Nr " Width="38" CanUserSort="True" x:Name="SP001" >
                        <DataGridTemplateColumn.CellTemplate>
                            <DataTemplate>
                                <Label x:Name="SP001F" Height="50" Content="{Binding GrLaufendePosition}" Foreground="Black" Background="White" HorizontalAlignment="Center" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" BorderThickness="0" VerticalAlignment="Center"  />
                            </DataTemplate>
                        </DataGridTemplateColumn.CellTemplate>
                    </DataGridTemplateColumn>

SP001.Foreground = "Red"; is wrong :-(
SP001F.Foreground = "Red"; is wrong too :-(

Have anyone a idea?

Best Regards

Bernd

There are many ways to do this, but the easier way is to refer with DynamicResource.

<DataGrid x:Name="dataGrid1" >
    <DataGrid.Resources>
        <SolidColorBrush Color="Black" x:Key="columnForeground"/>
    </DataGrid.Resources>

    <DataGrid.Columns>
        <DataGridTemplateColumn Header="Nr " Width="38" CanUserSort="True" x:Name="SP001" >
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate >
                    <Label x:Name="SP001F" 
                    Height="50" 
                    Content="{Binding GrLaufendePosition}"

                    Foreground="{DynamicResource columnForeground}" 

                    Background="White" 
                    HorizontalAlignment="Center" 
                    HorizontalContentAlignment="Center" 
                    VerticalContentAlignment="Center" 
                    BorderThickness="0" 
                    VerticalAlignment="Center"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
        </DataGridTemplateColumn>
    </DataGrid.Columns>
</DataGrid>


this.dataGrid1.Resources["columnForeground"] = Brushes.Red;
