How to set colors of text in specifics cell in WPF DataGRID

I have a method which comparing data in two dataTable. After comparing I´d like to visualizing these compared data (which are in new DataTable called ChangeTab) in WPF dataGRID.

I´m filling datagrid from DataContext:

win.TableOfChange.DataContext = ChangeTab.DefaultView;

<DataGrid ItemsSource="{Binding}" Height="107" HorizontalAlignment="Left"....

I´m fighting with problem, how to visualize data which are different (in the DataTables) by red, and data which are the same with green color - similar like is in the picture:

enter image description here

Is there is a way, how to do that (Set colour to WPF dataGRID cell for some red and some green from C#)?

Thanks a lot!

I tend to use DataTemplates for most columns in the grid. You would need to create a class, something like this:

class CellContent
{
    public object Content { get; set; }
    public bool IsDifferent { get; set; }
}

Then create a datatemplate something like this:

<DataTemplate x:Key="bob">
    <ContentPresenter Content="{Binding Path=Content}" TextElement.Foreground="{Binding Path=IsDifferent, Converter={StaticResource myConverter}}" />
<DataTemplate>

You then assign the template to each column.

The other option which is probably better would be to use a Trigger to change the colour if the IsDifferent is true.

I presume that you build the source table in the comparison process, if so you can easily store a boolean value that indicates equality. Then in the CellStyle you can use a DataTrigger on that property and have a Setter change the TextElement.Foreground property to the desired value.
