US Patent 7930646 Dynamically updated virtual list view

A virtual list view in a web application is dynamically updated such that a user can seamlessly access and manage the presented data despite the inherent latency involved with the web. Data associated with the virtual list view is downloaded in chunks and the view updated as the user scrolls. By coupling the user's scrolling and particular chunks of data to be downloaded system resources are utilized in an efficient manner. Additional user interface controls for the user interface are employed for rapid and efficient access to portions of data minimizing delay and system resource occupation.
