Usually, I define a grid based on an alias which I can see at design and run time. However, I have a form where I am designing a grid but that grid will be bound on a cursor that I am defining in the Init() of the form. So, I have something like this:

MESSAGEBOX(ThisForm.ControlFile.Columns(1).ControlSource)
MESSAGEBOX(ThisForm.ControlFile.Columns(2).ControlSource)

which gives the proper field names. Then, I assign the grid to the cursor which I just created in the Init() of the form:

ThisForm.ControlFile.RecordSource='Control'
MESSAGEBOX(ThisForm.ControlFile.Columns(1).ControlSource)
MESSAGEBOX(ThisForm.ControlFile.Columns(2).ControlSource)

Both ControlSource are now empty. Anyone can tell me the trick to preserve the grid properties?
