Hi Ryan.

HI, how to lock specific row,column in the grid to avoid editing records while im inserting new record under the same grid.

if I correcly understand what you are trying to do, what you want to do is add a custom template method called "ValidateCurrentRow" to your grid class. The validation code in this method goes in the instance. Add the following code ( This code requires version 7 or later to run) to BeforeRowColChange:

LPARAMETERS nColIndex
WITH This
  IF INLIST( .RowColChange, 1, 3 )
    *** If we are trying to move to a new row
    *** validate the current row
    IF NOT EOF( .RecordSource ) AND RECCOUNT( .RecordSource ) > RECNO( .RecordSource )  
      *** Do not allow the move if the validation fails
      IF .ValidateCurrentRow()
        *** peachy keen go ahead and move off the row
        *** and make sure the highlight gets reset
      ELSE
        NODEFAULT
      ENDIF	
    ENDIF
  ENDIF
ENDWITH
