Templates with Editing

In this demo, the customShapeTemplate property defines a common shape template and adds the Edit and Delete links to a shape. These links allow users to modify and remove employee data from the data source. The Diagram component reloads modified diagram data whenever the data source changes.

The onRequestLayoutUpdate function specifies whether the component must reapply its auto layout once the diagram is reloaded.
