Remarks

An ItemsPanelTemplate object element should contain exactly one FrameworkElement-derived class that serves as the root element for items. In most cases this is a Panel-derived class. The expanded template serves as the parent for the realized items and there generally is more than one item. Therefore the XAML content property of the intended root element of an ItemsPanelTemplate should support a collection, as Panel.Children does.

Important

The root element of the template declared for the ItemsPanelTemplate in the GroupStyle.Panel property cannot be a virtualizing panel. Virtualizing panels are defined as any type that derives from VirtualizingPanel, for example the VirtualizingStackPanel class.

Constructors

ItemsPanelTemplate()

Initializes a new instance of the ItemsPanelTemplate class.

Properties

Dispatcher	Always returns `null` in a Windows App SDK app. Use DispatcherQueue instead. (Inherited from DependencyObject)
DispatcherQueue	Gets the `DispatcherQueue` that this object is associated with. The `DispatcherQueue` represents a facility that can access the `DependencyObject` on the UI thread even if the code is initiated by a non-UI thread. (Inherited from DependencyObject)

Methods

ClearValue(DependencyProperty)	Clears the local value of a dependency property. (Inherited from DependencyObject)
GetAnimationBaseValue(DependencyProperty)	Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject)
GetValue(DependencyProperty)	Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject)
ReadLocalValue(DependencyProperty)	Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject)
RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback)	Registers a notification function for listening to changes to a specific DependencyProperty on this DependencyObject instance. (Inherited from DependencyObject)
SetValue(DependencyProperty, Object)	Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject)
UnregisterPropertyChangedCallback(DependencyProperty, Int64)	Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback. (Inherited from DependencyObject)
