John,

Actually with the way you are doing it, all you should need to do is wrap the SELECT statement with the following:

In the AfterRowColChange method:
LOCAL lcAlias as String
* Only do this when the row changes
IF INLIST(this.RowColChange, 1, 3)
  WITH this.Parent.grdChild
    lcAlias = .RecordSource
    .RecordSource = ''
    * Requery here
    SELECT ... INTO CURSOR (lcAlias) ...
    .RecordSource = lcAlias
  ENDWITH
ENDIF

HTH,
Chad


>>VFP8. I have a form with parent record data and two grids to display data from child records. I use an SQL select to create cursors for the grids which use the cursors for a record source. When the form opens the grids with the child record data display correctly. However, if I move to a new parent record and at the same time do new SQL select statements using the same cursor name to get new child data for the grids, the grid data and headings disappear and remain missing until I start all over again. What am I doing wrong? TIA.
