.NET Framework (current version)
Gets or sets the number of actions stored in the undo queue.
PresentationFramework (in PresentationFramework.dll)
member UndoLimit : int with get, set
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.
UndoLimit is introduced in the .NET Framework version 3.5. For more information, see .NET Framework Versions and Dependencies.
