I just released my latest updates to the Ajax Snippets project, the following notes summarise whats new.

ADDED

• SnippetCallback now has an action list item, 'Javascript function stubs to clipboard'
• SnippetCallback now has a designer action list option to configure the callback through a wizard
• Ability to override default value extractors and add new ones
• The Map parameters wizard step of the SnippetCallback wizard now best guesses the mappings by matching the name of the parameter to a control id
• Snippets can now be used as ordinary web user controls where they can be dropped straight on a page with the advantage of SnippetCallbacks
  

FIXED

• Javascript function stubs to clipboard feature was creating incorrect javascript
• SnippetCallback wizard was not saving WebServiceVirtualPath property
• Snippets now throw the correct exception if errors occur whilst retrieving them from a web service
• SnippetManager was not managing css references correctly
