Remarks

By default, the uppermost connector and diagram item defined in XAML within the TemplateDiagram are used as templates for the connectors and diagram items representing data objects.

You can use the DiagramDataBindingBehaviorBase.GenerateItem and DiagramDataBindingBehaviorBase.GenerateConnector events to implement custom logic for choosing the item and connector template. To do this, create diagram items/connectors in the TemplateDiagram and specify their names using the DiagramItem.TemplateName property. Specify the name of the desired template as the event’s CreateItemFromTemplate / CreateConnectorFromTemplate method parameter.

Alternatively, you can use the DiagramDataBindingBehaviorBase.ItemTemplateSelector property.
