How to programmatically Show/Hide Annotations in WPF Diagram ?

1 min read
In the WPF Diagram (SfDiagram), we have support to customize the visibility of Annotation. This can be achieved by using a custom class from AnnotationEditorViewModel and the ViewTemplate property of Annotation. We have provided code examples, samples, and screenshots to represent this.

Please refer to the code example, sample, and screenshots below.


//Annotation collection
           node.Annotations = new ObservableCollection<AnnotationEditorViewModel>
                new Annotation()
                 //set visibility as Visible|Collapsed to Annotation content
                 ViewTemplate=this.Resources["viewtemplate"] as DataTemplate
Here, node is instance of Node.
