DataGrid RowStyle trigger bind with dynamic list

Hi, I have a datagrid that is loaded with data first (data1), then I want to set rows to Red foreground color where columns C2 matches a given list of strings.
case:
1. Load with Data1
-> provide List1 and rows with C2 matching this list should have Red foreground color
-> provide List2 and only rows with C2 matching this list should have Red foreground color
2. Load with Data 2
-> repeat with the above 2 Lists for C2 values

In the xaml I hard-coded for row to be Red where C2 value is "A", how to set this to match a list at runtime?
