How to restrict annotation editing by double-clicking the node or connector in WPF Diagram (SfDiagram)?

2 mins read

The Read-Only property in AnnotationEditorViewModel will not allow to get annotation edited in WPF Diagram (SfDiagram). The AnnotationChanged event will assist to decide on editing the annotation by double-clicking the node or itself (Annotation).

Refer to the code example to stop editing the annotation when double-clicking the node. But the annotation should get edited when double-clicking the annotation.


(diagram.Info as IGraphInfo).AnnotationChanged += AnnotationChanged;
//Here diagram is the instance of SfDiagram
private void AnnotationChanged(object sender, ChangeEventArgs<object, AnnotationChangedEventArgs> args)
  // Verify that the double-clicked item is Node
  if(args.Item is NodeViewModel)
    // To Cancel Annotation editing
    args.Cancel = true;
