What improvements can I expect with the latest upgrade to the AJAX Map Control?
The new 6.3 control includes new methods that makes it easier to code popular functionality with new methods for draggable pushpins and one box style search. The new CORE mode feature is best for basic locator-like scenarios and when used, can improve side-by-side control load performance by up to 41%(*).
