Support to disable the undo and redo operations
23 May 20261 minute to read
The undo operation using both the UndoCommand and keyboard shortcut Ctrl+Z can be enabled or disabled using the IsUndoEnabled property. The default value of this property is true.
PdfViewer.IsUndoEnabled = false;NOTE
Redo can be performed only if undo is enabled. So, enabling or disabling undo, effectively enables and disables redo as well.
