If I remember well,
You can create this form using Same Tables as Main (that with Grid).
In Init event of the Main form BINDEVENT() of "DoubleClick" of each Column control to Some Method of The form i.e. ShowOutLook()

this.Method Must look like this:

IF RECCOUNT(thisform.Grid1.RecordSource) == 0 &&7 Empty Table
   RETURN && Nothing to Show
ENDIF
thisform.outForm = NULL
DO FORM MyOutLook NAME thisform.outForm WITH (thisform.Grid1.RecordSource+".IdField") LINKED

In Init Event of the MyOutLook

LPARAMETERS tableId
SELECT MyTable
SEEK tableId

**** Refresh Controls
