How to display the paste context menu only after cutting or copying nodes in a diagram in WPF Diagram (SfDiagram)?
In the WPF Diagram, you can display the paste context menu only after cutting or copying nodes by creating a custom boolean property in a class that derives from the DiagramMenuItem class. Bind this custom property to the Visibility property of the menu item’s style using a Boolean-to-Visibility converter. By setting the custom property to true, you enable the visibility of the MenuItem, allowing it to appear when appropriate.
