Features overview
Unlike the standard Wrap panel, this control automatically viritualizes, realizes, and arranges the associated content, by automatically creating and destroying the containers for the content items.
Instead of letting the layout system generate all the UI elements that are associated with the control (i.e. all items from the content), the control automatically works out the number of elements that will be displayed in the viewport, and creates the UI element containers for only those elements that will be visible at any given time in the control.
Core features
No procedural code needed to setup the control
In contrast to the very powerful features in the control, you will find it extremely easy to setup and run the control in your applications with absolutely no procedural code.
Either using Designer tools like MS Expression bLend or such other designer tools, or even with hand-cranked one line of XAML, you will be able to run the control in just few seconds.
You can see a screen-shot here that displays a Code Snippet where the control has been setup in just one line of XAML, which instantiates the BinaryVirtualizingWrapPanel control, and sets it as the ItemsPanelTemplate, having configured some of its rich UI properties as well.
Custom layout management
The control is written from scratch, and implements custom Logic for content layout and scrolling.
The control supports two layout orientations viz., Horizontal and Vertical Orientations, and fully custom implements IScrollInfo interface for scrolling support.
Custom item dimension / sizing
The child items hosted in the control can have differing Height and Width values.
"On demand" realizing of a desired child item
The control is capable of realizing a specified item from the associated data-bound source and scroll it into view, given the item's index.
Configurable "virtualization" scheme
