5Widgets is a framework for building HTML5 canvas interfaces. Written in JavaScript, 5Widgets consists of a library of widgets and a controller that implements the MVC pattern. Though the HTML5 standard is gaining popularity, there is no framework like this at the moment. Yet, as a professional developer, I know many, including myself, would really find such a library useful. I have uploaded my initial code, which can definitely be improved since I have not had the time to work on it full time. You are welcome to join and create widgets to add to the library, improve the controller, or even revamp the architecture of the framework.

Just by adding this small JavaScript module to the end of your web pages, you get your form's submissions intercepted and, instead of sending request to the server in the usual way, they are done asynchronously and in an AJAX-style smooth way. As long as it is a client-side library it will work with any server technology: ASP.NET, PHP, JSP, Classic ASP... and even with local HTM files. I've included extensibility so that you can add easily your own progress indicators (several included) and show error messages the way you prefer (by default it shows an alert). It's transparent to your server code and could be used to add AJAX capabilities to some applications without writting a single line of code. Documentation is included.

Abstraction library which enables the authoring of Ajax ScriptControl objects which can be consumed by both WebForms and MVC applications.

Ajaxna is a javascript API enabling 3D games for the web, without using plugins. This programming framework targets Visual Studio 2008, follows an XNA inspired API, is implemented as a C# ASP.NET control and is built around dynamic client class (lazy) loading and intellisense.

Extensions to the AJAX Control Toolkit. The project includes a set of extenders, controls and samples that complement the AJAX Control Toolkit.

There are several approaches to use ajax callback in ASP.NET. We can use PageMethods in WebForms (but not in User Controls), ScriptServices or implement ICallbackEventHandler for your code-behind class and even use jQuery post or get methods to call webforms or pagemethods (but not methods from your own user controls). But they all have some disadvantages or limitations, for instance, using UserControl you can’t use PageMethods in the control declaration (inside markup and scripts), using Script Services you are forced to spread the logic specific to current user control only throughout the web application despite of placing this logic inside your code-behind user control class. ICallbackEventHandler approach is more powerfull but also more difficult and more specific to current user control logic. This project aims to allow developer to use server side methods in the client scripts more easily and more convinient without any unnecessary actions to provide serialization/deserialization parameters or results from server side (for example, using json), using only the same method signatures on the client side as they are declared on the server side code-behind class. Only one agreement will be required - declared server side method have to return AjaxResponse or its inherited class value. Needless to say that all parameters either to call server side method or return value from method must meet the requirements to be serializable.
