How to set color of DataGridRow if it has same specific values in some of columns ?

Hello

DataGrid has columns from DataTable: 

myDataGrid.ItemsSource = dataTable.AsDataView();            

I want have color row in DataRow if 5 of 7 columns on load dataTable has specific value. And every one of this 5 is next to "cell" with that value.

What is the best way to do this?

Best Regards
