Remarks

When the ASPxDiagram control is bound to an edge data source (EdgeDataSource), the control creates a DiagramEdge object and raises the EdgeDataBound event for every data item in the source.

You can access the processed DiagramEdge object via the event argument’s Edge property. Use the object’s properties to customize the edge before it is finally rendered.
