By Tales from the Evil Empire : Microsoft AJAX Library Last week, I wrote a post about how the new Microsoft Ajax Library Preview 6 made it a lot easier to write unobtrusive and imperative data-driven applications . Because for the previous preview, I had written a cool little class browser using a declarative style, I thought it would be nice t...

By Tales from the Evil Empire : Microsoft AJAX Library Today is the release of the sixth preview of Microsoft Ajax Library.

By ScottGu Areas provide a means of grouping controllers and views to allow building subsections of a large application in relative isolation to other sections. Each area can be implemented as a separate ASP.NET MVC project which can then be referenced by the main application. This helps manage the c...

By Jan Tielens So how is all of this implemented? Well the idea is to display an HTML textbox in a Content Editor Web Part.

By tony_lombardo A current snapshot of results shows that 76% of developers are using jQuery, compared with 48% using ASP.NET AJAX and 58% using AJAX Toolkit.  Does that really mean that there are more jQuery developers than WebForms/ASP.NET AJAX developers?  To confuse matters, AJAX Control Toolkit is b...

By Jan Tielens So how can this be solved with the help of jQuery? Well besides a very powerful DOM Selectors API, the jQuery library also has a DOM Maniplation API.

By Bertrand Le Roy On the client-side, the browser provides two ways to generate HTML: innerHTML and the DOM API. Template rendering is of course possible, but only using a JavaScript library.

By oazabir So far you have seen simple object and list serialization. A best practice is to return a common result object that has some status, message and then the real payload. It's handy when you only need to return some error but no object or list. I use a common Result object that has three properties -...
