Recently, using Ajax has been dramatically increased among web developers. After Google started its free email service called GMail and used Ajax in it, this technology became more popular and many developers and companies tried to build tools and frameworks for various server side technologies to be able to use Ajax benefits more easily.

From my personal view, Ajax will give your visitors a better surf and they will not bother from multiple refreshes for a single task. I have tested and used Ajax.NET Pro in my recent projects. This framework was written in C# by Michael Schwarz. I think that this framework is powerful and easy to use and implement.
Michael has a personal blog in which he writes about his open source framework. He has also created a group at Google for Ajax.NET Pro.

Two different versions of Ajax.NET Pro are available for ASP.NET 1.x and 2.0.

If you want to know more about other Ajax tools for ASP.NET take a glance at this comparison.

I'm so glad to see that many Iranian developers are using Ajax in their web sites. Even if you use Ajax in a small part of you web site it is admirable. For example quick vote and tell a friend sections at ketabeavval.ir that has been programmed by my dear friend Mohammadreza Taheri.

I have shown some simple usages of Ajax in razmpa.com. If you are an ASP.NET developer and have used Ajax in your projects please send their URLs and I will put them in an update in this post.
