Silly me. I knew that but that wasn't working so I started testing everything else (which didn't work either). Of course I was obviously doing something wrong in all of my testing because when I did it again the right way (as both you and Naomi suggested), it worked! Thanks Borislav!!

>>Grid sits on a page on a pageframe. Clicking on the page loads the grid. Everything works except that I want to specify a different control and controlsource for the 2nd column:
>>

>>*Page Activate:
>>   loObject = THIS.Grid1.Column2
>>   THIS.Grid1.RECORDSOURCE=""
>>   THIS.Grid1.RECORDSOURCE="Tracy"
>>   IF !PEMSTATUS(loObject,'Edit1',5)
>>      WITH THIS.Grid1.Column2
>>        .REMOVEOBJECT([Text1])
>>        .ADDOBJECT([Edit1],[EditBox])
>>        .CURRENTCONTROL = [Edit1]
>>        .Edit1.CONTROLSOURCE = "(thisform.returntheaddress())"
>>        .Edit1.VISIBLE = .T.
>>      ENDWITH
>>   ENDIF
>>*Form returntheaddress method (field names are correct and all are character):
>>   RETURN (ALLTRIM(number) + IIF(!EMPTY(apt_room),"-" + TRIM(apt_room),' '))
>>*This fails as well:
>>   RETURN "Test Value"
>>

>>When the pagetab is clicked, the following error appears:
>>Parent object will not allow this property setting for form1.pageframe1.page1.grid1.column2.controlsource.
