Check out Part 4 of 4 in my blog series for Magenic featuring Windows Store Apps Using HTML5 – UI Virualization (Part 4 of 4). In this article, I introduce UI Virtualization using asynchronous data template functions. The performance of Windows Store Apps is important to consider, especially when handling large collections of data. When displaying the collection, performance can be degraded. In part three, the first steps were taken to alleviate the performance problems that can arise under heavy data usage. Part four will describe further performance improvements using UI virtualization.
Asynchronous data template functions enable substantial user experiences by keeping an app responsive and informative. This article’s implementation of UI virtualization relies on these concepts of asynchronous data template functions. The following sections will describe the main components of the implementation along with the differences from simple asynchronous data template functions. The first to be examined is the markup.
