ASP.NET AJAX cheat sheets
“Milan Negovan from the really nice PDF “cheat sheets” for the client-JavaScript libraries in ASP.NET AJAX:
These are super handy pages to print out and keep around to quickly find information and code-snippets to use.
Milan is making these available completely for free – so definitely download them and send him feedback (he is going through and adding them for all the core classes in the client-side AJAX library).”
