Public Property DiagramPageBackgroundTemplateSelector As DataTemplateSelector

Property Value

Type	Description
DataTemplateSelector	A DataTemplateSelector descendant that applies a template based on custom logic.

Remarks

A template that defines the presentation of the drawing page background is specified by the DiagramControl.DiagramPageBackgroundTemplate property. If you have more than one template that can be used to render the page background, you can implement custom logic to choose the required template. To do this, derive from the DataTemplateSelector class, implement the SelectTemplate method that returns the template which meets the required condition, and assign it to the DiagramPageBackgroundTemplateSelector property.

If both the DiagramControl.DiagramPageBackgroundTemplate and DiagramPageBackgroundTemplateSelector are specified, the drawing page background is rendered using the template returned by the template selector. If the template selector returns null, the template specified by the DiagramControl.DiagramPageBackgroundTemplate property is used.
