Declaration
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 printed page background is specified by the DiagramControl.PrintPageBackgroundTemplate 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 a template which meets the required condition, and assign it to the PrintPageBackgroundTemplateSelector property.
If both the DiagramControl.PrintPageBackgroundTemplate and PrintPageBackgroundTemplateSelector are specified, a band header is rendered using the template returned by the template selector. If the template selector returns null, the template specified by the DiagramControl.PrintPageBackgroundTemplate property is used.
