Adds the specified UIElement to the InternalChildren collection of a VirtualizingPanel element.

Called after an item is measured in order to update scrolling structures.

Called after the item was prepared to be shown in the panel.

Positions child elements and determines a size for a UIElement. Parent elements call this method from their ArrangeCore(Rect) implementation (or a WPF framework-level equivalent) to form a recursive layout update. This method constitutes the second pass of a layout update.

Provides the behavior for the Arrange pass of Silverlight layout. Classes can override this method to define their own Arrange pass behavior.

Called before the item is recycled.

When implemented in a derived class, generates the item at the specified index location and makes it visible.

Converts a length from render coordinates to layout coordinates in order to implement zoom panel easily.

Determines whether the specified Object is equal to the current Object.

Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.

Returns the current effective value of a dependency property on this instance of a DependencyObject.

Adds the specified UIElement to the InternalChildren collection of a VirtualizingPanel element at the specified index position.

Invalidates the arrange state (layout) for the element. After the invalidation, the element will have its layout updated, which will occur asynchronously unless subsequently forced by UpdateLayout()()()().

Invalidates the measurement state (layout) for the element.

Updates the DesiredSize of a UIElement. Parent elements call this method from their own MeasureCore(Size) implementations to form a recursive layout update. Calling this method constitutes the first pass (the "Measure" pass) of a layout update.

Provides the behavior for the Measure pass of Silverlight layout. Classes can override this method to define their own Measure pass behavior.

Creates a shallow copy of the current Object.

When overridden in a derived class, is invoked whenever application code or internal processes call ApplyTemplate()()()().

Called when the collection of child elements is cleared by the base Panel class.

Returns class-specific AutomationPeer implementations for the Windows Presentation Foundation (WPF) infrastructure.

Called when the Items collection that is associated with the ItemsControl for this Panel changes.

Raises the property changed event.

Returns the local value of a dependency property, if it exists.

Refreshes this instance by removing all the children and creating them again.

Releases the mouse capture, if this element held the capture.

Removes the specified routed event handler from this element.

Removes child elements from the InternalChildren collection.

Sets the local value of a dependency property, specified by its dependency property identifier.

Returns a String that represents the current Object.

Gets or sets the horizontal alignment characteristics applied to this element when it is composed within a parent element, such as a panel or items control. This is a dependency property.

Gets or sets a value that declares whether this element can possibly be returned as a hit test result from some portion of its rendered content. This is a dependency property.

Gets or sets a value that indicates that this Panel is a container for user interface (UI) items that are generated by an ItemsControl. This is a dependency property. 

Gets a value that identifies the ItemContainerGenerator for this VirtualizingPanel.

Gets or sets the height of each item.

Gets or sets the minimum height constraint of the element. This is a dependency property.

Gets or sets the minimum width constraint of the element. This is a dependency property.

Gets or sets the identifying name of the element. The name provides a reference so that code-behind, such as event handler code, can refer to a markup element after it is constructed during processing by a XAML processor. This is a dependency property.

Gets or sets the opacity factor applied to the entire UIElement when it is rendered in the user interface (UI). This is a dependency property.

Gets or sets an opacity mask, as a Brush implementation that is applied to any alpha-channel masking for the rendered content of this element. This is a dependency property.
