MyGrid.RecordSourceType = Alias.

MyGrid.RecordSource:

AppointmentTypeSets.Colors,FromDate,ToDate,Day,StartTime,EndTime

The grid is not populating, though the Alias has records.

If I just put this:

AppointmentTypeSets

Then the grid populates, but not in the field order that I want.

I now remember why I started to not like grids many years ago. They are a pain to work with.
