Help us shape the 2021 DevExtreme Roadmap.
Take our 5 minute survey.
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 UI component reloads modified diagram data whenever the data source changes.
The onRequestLayoutUpdate function specifies whether the UI component must reapply its auto layout once the diagram is reloaded.
The customDataExpr property links custom employee information from the data source to diagram nodes. Changes made to data are reflected in the diagram’s history. Undo and redo actions (available within the control’s UI) allow users to rollback/reapply changes.
The CustomShapeToolboxTemplate property specifies the template used for a shape within the toolbox.
Feel free to share demo-related thoughts here.
