C# code equivalent for Applying RowValidationRules on DataGrid in WPF

  <local:MyValidationClass ValidationStep="UpdatedValue"/>
</DataGrid.RowValidationRules>

This should do the trick:

grid.RowValidationRules.Add(new CourseValidationRule() { 
                ValidationStep = ValidationStep.UpdatedValue 
            });

Note that you need to set the ValidationStep.
