AccordionControl.AllowVirtualization Property

Gets or sets a value indicating whether virtualization is enabled for vertical scrolling. This is a dependency property.

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

Expanded Syntax

Property value

Type: Boolean
true, to enable virtualization; otherwise, false.

Expanded Remarks

Use the AllowVirtualization property to speed up the performance of an AccordionControl displaying a large number of items.

When the AllowVirtualization property is set to true, the AccordionControl only renders accordion items that are currently visible.

Note

Virtualization is not supported in the AccordionViewMode.NavigationPane view mode.
