c# - changing text color of an xamdatagrid

Question

I found out how to change the text color from a xamdatagrid cell. Right now I'm doing it like this:
rec.FieldLayout.Fields["Message Category"].Settings.CellValuePresenterStyleSelector = colors;
rec is a datarecord. and colors is a StyleSelector
is there anyway I can do this but instead of just changing one cell I can change the entire row?
