Search Ajax control
Highrise and other new Ajax enabled tools have this feature that when you type in a search query, it automatically updates the search results below. It's almost like a Auto-Complete Box, but with full results on the page instead of a drop down list below the control. Unfortunately I didn't find anything like this in the Microsoft ASP.NET Ajax Toolkit.

Error logging techniques using Database
Nowadays error logging becomes mandatory and there has been lots of techniques/API's to log the errors. We develop a ASP.NET application and it works fine on your development machine, and when we deploy the application to the production we set the <compilation debug="false" ...> element in your web.config , of course it is the best practice, which makes the error not visible to the end users.
Well, now, we got some exception and we wonder what is that error and you don't have any clue about error since we have not logged the exception and we were left at no man’s land and makes the developer job very tough without any clue about the error and hence we expect is to log the error and a notification mail to sent to the development so that we make the developer job much easier which is even best practice.
In following article we are going to cover the topics on how to log the error in a simple way and of course in a efficient manner. -
ASP.NET/Silverlight component development
Almost all of the Silverlight demos you see out there are completely client-side, and invoke Web services to post/get data. This approach makes sense, but when you want to use Silverlight to functionally enhance your existing website, you may want to have some kind of integration between Silverlight objects and your server-side controls.

Scrolling Data Pagination using Ajax
Tired of continuously clicking next page, next page, next page to find the data you are looking for? I always thought this was just something you had to deal with when viewing data on the Internet, that was until I took a look at the new Microsoft live image search. Instead of forcing the user to click next page to paginate the data the page catches the scroll event and fetches the next page of data and adds it to the output asynchronously. In this project I will expand upon my previous project Using Linq to paginate your ObjectDataSource, replacing the standard grid with a scrolling paginated grid. This example works by first creating an Ext JS grid, making a call to a custom json rpc handler to retrieve data, and by adding an event listener to the scrolling event of our grid. This article will focus primarily on the AJAX portion of this project to read more on the underlying data pagination technique please take a look at the previous version of this project.

Accessible UpdatePanel
UpdatePanel is a great way to add Ajax features to an ASP.NET application at a minimal cost. Because it's based on regular postbacks, it also degrades gracefully when JavaScript is not present. But one thing it doesn't do well out of the box - and this is actually the case for any asynchronous update to the DOM - is informing screen readers that new content is present. This article by Bertrand Le Roy and the accompanying code show how to work around that problem and give assistive technology users access to the benefits of Ajax.
