I would like some recommendations on the best way to handle errors in AJAX-powered applications. Specifically, the methods used to log the errors and what do you do to address them.

Basically, I'm trying to type for something (say 'United' in a country field). I would expect the auto suggest feature to suggest 'United States of America' and 'United Kingdom' for example. On top of this, I would like to select both 'United States of America' and 'United Kingdom' by clicking on a link or button available directly on ...
I'm trying to figure out if there's a way I can somehow notify a web browser of an event from a web server. I know Ajax lets you asynchronously make a request to update a section of a page. I guess I could have a timer periodically ask for updates. But, I'd prefer to avoid a polling scheme, if possible. Is there a better way to go and ...

Does anyone know of a way that I can stop all the .NET AJAX scripts from rendering, even if a ScriptManager exists on the page? The ScriptManager's Visible property has been overridden and disabled so that you receive a NotImplementedException if you try to set the Visible property. The reason I would like to do this is that I don't wa...
I used SPRY about a year ago to experiment with the fact that you could essentially load a "dataset" into Javascript/browser, and act upon that to bind to form fields like textboxes, combo dropdowns etc. I really have been trying to find something really simple to allow me (a coder) to write the backend code to get the data, and my part...

I'm working on an application that will run on Google AppEngine. I plan to have the web interface of that application wait, among many other things, for notifications coming from the AppEngine server.

Hello. I'm writing an application that uses the WebBrowser control to view web content that can change with AJAX that adds new content/elements. I can't seem to get at the new elements any way I've tried. BrowserCtl.DocumentText doesn't have the up-to-date page and of course it's not in "view source" either. Is there some way to get thi...
