DiagramDataBindingBehaviorBase.GenerateItem Event

Fires before generating a diagram item representing a data object and allows you to customize it.

Namespace:DevExpress.Xpf.Diagram
Assembly:DevExpress.Xpf.Diagram.v18.1.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type DevExpress.Xpf.Diagram.DiagramGenerateItemEventArgs containing data related to this event.

Expanded Remarks

By default, the uppermost diagram item defined in XAML within the TemplateDiagram is used as the template for the diagram items representing data objects.

You can use the GenerateItem event to implement custom logic for choosing the item template. To do this, create diagram items in the TemplateDiagram and specify their names using the DiagramItem.TemplateName property. Specify the name of the desired template as the event's CreateItemFromTemplate method parameter and assign the method return value to the event's Item property. See the example below.

Alternatively, you can use the ItemTemplateSelector property.
