Thanks for the reply Hilmar. Changing sparse does no correct the problem. I am using code like this:

If pemstatus(oCol,'Text1',5)
	If Not pemstatus(oCol,'btext1',5)
		oCol.AddObject('bText1',lcTextClass)
		For i = 1 To Amembers(laProp,oCol.Text1)	&& Get all properties
			If pemstatus(oCol.Text1,laProp(i),0) And laProp(i) # 'NAME'
				Store Eval('ocol.Text1.'+laProp(i)) To ('ocol.bText1.'+laProp(i))
			Endif
			Store oCol.Text1.Width To oCol.bText1.Width
			Store oCol.Text1.Height To oCol.bText1.Height
			oCol.Sparse=.T.
		Endfor
		oCol.CurrentControl = 'bText1'
	Endif
	oCol.RemoveObject('Text1')
ENDIF 

I am doing this because I am trying to allow dynamic grid configurations based upon desired behaviors. For instance If grid sorting is required I would load the grid with the appropriate controls at runtime, but if sorting is not required the normal control will suffice.
