I wrote a short column in Dino Esposito 's latest MSDN Magazine article to introduce two new features that we will ship with the next version of ASP.NET Ajax . The features will enable you to declaratively instantiate client-side components and to build data-driven HTML from simple templates. http:/...

I've been seeing more and more authors lately dismissing partial rendering (a.k.a. UpdatePanel) as a poor man's version of Ajax, something you should only choose if you're too lazy to implement "true" Ajax. I think that view not only has a slightly pedantic ring (isn't laziness one of the most...

For some reason, there is no standard API to get the pixel coordinates of a DOM element relative to the upper-left corner of the document. APIs only exist to get coordinates relative to the offset parent. Problem is, it's very important to get those coordinates for applications such as drag and drop...

Using Ajax.NET Professional (AjaxPro) you are able to put you AJAX methods wherever you want, if inside the Page class itself, any .NET class in the same project or as a reference class library. To generate the AJAX client-side JavaScript proxies the AjaxPro library checks for all public methods inside...

It's a hell of a problem to track down because when you run...

Last week, I wrote about building a simple behavior to edit text in place . Almost at the same time, Nikhil was building a similar component for Silverlight , but it was considerably simpler because instead of substituting a label for the textbox on blur, he was just changing the border so that the textbox...

All client-side template engines enable you to create HTML (feel free to go ‘duh’). What they don’t all allow is the creation of event handlers and components over the markup they generate. The general approach with those engines is to do a second pass of code over the markup to create handlers and components...

When we built the history management feature in ASP.NET Futures, we spent considerable time experimenting with the different behaviors of the main browsers out there. The problem with such a feature is that it has to rely on a number of hacks because browser vendors basically never anticipated this need...
