The grid is not going to be blank if you SET DELETED OFF.
In Form's Init method you can put the following:

thisform.old_deleted = SET("DELETED")
SET DELETED OFF


In Form's Destroy method you can put the following code:

SELECT (thisfrom.grid.recordsource)
LOCATE FOR DELETED()
IF FOUND()
USE (thisfrom.grid.recordsource) AGAIN EXCLUSIVE && If the table is not
used exclusive
IF SELECT((thisfrom.grid.recordsource)) # 0
PACK
ENDIF
ENDIF
SET DELETED (thisform.old_deleted)
Of course you may handle the error (I can't remenber now what number).

In this way you can deleted some range of records and recall them if you just make a mistake.
