Need to set a cell to read only

[Michael]

Here is what I've been given:  The logic is bound to the grid as a conditional formatting.  On the RowLoaded Event the logic will see if the equipment is in use already.  If it is, it marks the entire row red with white forground.  However there are two editable cells that must be marked readonly.  If not this form will fail the QA testing.

So with only the RowLoadedEventArgs being passed, how do I get to the object to bind to the edit event to bind an event handler that cancels any edit???

If found I could easily do this by binding my record state to the IsReadOnlyBinding in my xaml.
