LinkViewModelBase
Telerik Diagramming Framework provides a list of ViewModels defined in the Telerik.Windows.Controls.Diagrams.Extensions.dll.
This article describes the LinkViewModelBase defined in the Diagramming Extensions.
Overview
The LinkViewModelBase class is a ViewModel designed to serve as a base ViewModel for RadDiagramConnections in a data-bound RadDiagram. As the connection can start from one shape and end in another one, the LinkViewModelBase class is defined to expose properties that track these source and target shapes.
Essentially the LinkViewModelBase derives from ItemViewModelBase and therefore the class exposes all properties defined in the ItemViewModelBase class. Moreover, the LinkViewModelBase class inherits the ILink
