Clears the contents of the specified cell or range of cells.  This will not delete or change format or property of any cells.  It only replaces the contents of the cell with empty string (if string format), or 0 if a numeric format.   The function return TRUE if successful.

Example:

OPTION BASE 1

DIM nControl AS INTEGER

nControl = GRID.Create( "Graph", WS_VISIBLE, 0, 0, 320, 240, NULL, 1 )

GRID.RowCount( nGrid, 32 )

GRID.ColumnCount( nGrid, 8 )

GRID.SetDefaultType( nGrid, MG_CELL_INTEGER )

' Initialize Grid

DIM row AS INTEGER

DIM col as INTEGER

DIM num AS INTEGER

num = 1

FOR row = 1 TO 32

  FOR col = 1 TO 8

     GRID.ItemInteger( nControl, row, col, num )

  ENDFOR

ENDFOR

' Update Grid

GRID.Refresh( nControl )

' Clear 2nd Row

FOR col 1 TO 8

  GRID.Clear( nControl, 2, col )

ENDFOR

' Update Grid Again

GRID.Refresh( nControl )

GRID.Close( nControl )
