RadDiagram is an ASP.NET WebForms wrapper for the Kendo UI HTML5 Diagram and it exposes the rich API of the widget Client-Side – its methods and events.

The Kendo UI widget is exposed through the get_kendoWidget mthod of the RadDiagram’s client-side object, e.g.:

var diagramWidget = $find("<%= theDiagram.ClientID %>").get_kendoWidget();

Also, RadDiagram offers server-side properties for assigning handlers to the events:

Server-Side Properties:

  • OnLoad - defines handler for the Load event
  • OnSelect - defines handler for the Select event
  • OnClick - defines handler for the Click event
  • OnMouseEnter - defines handler for the MouseEnter event
  • OnMouseLeave - defines handler for the MouseLeave event
  • OnPan - defines handler for the Pan event
  • OnItemBoundsChange - defines handler for the ItemBoundsChange event
  • OnChange - defines handler for the Change event
  • OnItemRotate - defines handler for the ItemRotate event
  • OnZoomStart - defines handler for the ZoomStart event
  • OnZoomEnd - defines handler for the ZoomEnd event

The diagram can be data bound on the client-side to a Kendo hierarchical data source via the Kendo UI Diagram widget.
