Esparta,
I say use a property because 'been there done that' :)
Checking controlsource works, however you should do that at a point and on a column which you're sure not touched (controlsource might not be in form usedalias.fieldname) yet. To workaround the issue I did this (roughly) :

*GetGridCursor
with myGrid
 lnRecType = .recordsourcetype
 lcRecordsource = .recordsource
 .recordsource = ''
endwith

if lnRecType > 2
  thisform.addobject('dummy','grid') && Create a dummy one
  with thisform.dummy
    .recordsourcetype = lntype
    .recordsource = lcRecordsource && Populate
    lcCursorName = juststem(.columns(1).controlsource) && Get cursorname
  endwith
  thisform.removeobject('dummy') && Drop dummy
else
  lcCursorName = .recordsource
endif

myGrid.RecordSource = lcRecordsource

In most cases it doesn't worth to do all these (like using a sys(2015) for cursorname). I could just store it to a property :)
