TextBoxBase.LockCurrentUndoUnit Method

Definition

Namespace:

System.Windows.Controls.Primitives

Assembly:

PresentationFramework.dll

Locks the most recent undo unit of the undo stack of the application. This prevents the locked unit from being merged with undo units that are added subsequently.

public:
 void LockCurrentUndoUnit();

public void LockCurrentUndoUnit ();

member this.LockCurrentUndoUnit : unit -> unit

Public Sub LockCurrentUndoUnit ()

Remarks

Call this method when a non-text undo unit is added to the application's main undo stack. This prevents the locked unit from being merged with undo units that are added subsequently.
