- Localization support - The Toolkit now has an infrastructure for localizing the text in JavaScript files using the standard ASP.NET/AJAX support for resource files. There are placeholder files for the following 14 languages: Arabic, German, English, Spanish, French, Hebrew, Hindi, Italian, Japanese, Korean, Portuguese, Russian, Chinese (Simplified), and Chinese (Traditional). Complete localization of all strings hasn't been done yet, but our most popular request by far is for the string "Today:" at the bottom of the Calendar's popup - and that has already been localized to all of the above languages. Just set your system/browser's language settings to one of the supported languages and visit the Calendar sample page for a demonstration.
- JavaScript comment/whitespace stripping - People are always interested in keeping the download size of their pages as low as possible, and the Toolkit goes the extra mile to help. When compiled in "Release" mode (as the official releases on CodePlex always are), all of the JavaScript files in the Toolkit automatically have all comments and unnecessary whitespace removed. Ted, the author of this functionality, was careful to adhere to the ECMA-262 ECMAScript Language Specification, so the modifications are both safe and effective.
- ASP.NET Theme/Skin support - Central control is usually best, so it's nice to be able to use ASP.NET's theme/skin support to specify properties for controls across an entire web site in one central location. Toolkit controls didn't used to be skinnable (i.e., support the SkinID property) but now they are, so go ahead and start skinning your site. In fact, we used this new ability to style the CollapsiblePanels that we use for descriptions/properties/known issues on every sample page.
