Read reply(ies) in other forum too.
Here you changed the question a bit hence the solution changed a bit.
Are there only 2 controlsources ? If yes probably recordsource would also be "exp1table1" :

*form.init
WITH THISFORM.Grid1
  .RecordSource = '' && Keeps formatting
  if !used("exp1table1")
     use (THISFORM.tempfileAlias) alias "exp1table1" in 0
  endif
* update the grid record / control source
   .RECORDSOURCE = "exp1table1"
   .column1.CONTROLSOURCE  = "exp1table1.fldnumber1"
   .column2.CONTROLSOURCE  = "exp1table1.fldpet"
ENDWITH

THISFORM.tempfileAlias might be anything and this code would fail. ie: if that's really an alias and not the table/cursor name then use line would error. If that's something to be filled upon creation of class (with no meaningfull default value and/or datatype in class) then again would fail for you didn't set it. IOW it's hard to determine what the actual code should be.
Anyway code in other forum should make things clear for you.
PS: If you're a newcomer why are you using class based forms. IMHO class based forms don't have a neat superiority over non class based ones.
