Remarks

When the ASPxDiagram control is bound to a data source (NodeDataSource), the control creates a DiagramNode object and raises the NodeDataBound event for every data item in the source.

You can access the processed DiagramNode object via the event argument's Node property. Use the object's properties to customize the node before it is finally rendered.
