public int UndoLimit { get; set; }

member this.UndoLimit : int with get, set

Public Property UndoLimit As Integer

Property Value

Int32

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.

Exceptions

InvalidOperationException

UndoLimit is set after calling BeginChange() and before calling EndChange().

Remarks

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 Versions and Dependencies.
