How to restrict annotation editing by double-clicking the node or connector in WPF Diagram (SfDiagram)?
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.
C#
(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;
}
}Conclusion
