Property Value

The number of actions stored in the undo queue. The default is –1, which means the undo queue is limited to the memory that is available.

Setting UndoLimit clears the undo queue. When UndoLimit is set to –1, the undo queue is limited only by the memory that is available. When UndoLimit is set to 0, undo is disabled on the TextBoxBase.
