Hi!
clear empties the whole grid and sets RowCount = 0 and ColCount = 0
clean deletes the contens of the whole grid or of a subrange to cells[x,y] = ''
For more sophisticated actions ther are
DeleteColRow
InsertColRow
MoveColRow
ExchangeColRow
To your question:
What do you mean with "empty"?
If you want a blank Grid with no rows and no cells use clear.
If you don't want to change the RowCount and ColCount but to empty the contents then use clean.
Yes, not such a lucky syntax - just one char away…
