Beginning Ajax and ASP.NET 3.5

Ajax is a great helper to us while developing rapid applications without worrying us at power of asynchronous. In Visual Web Developer 2008 comes with built in Atlas and ASP.NET3.5 . In this tutorial, I try to show you what's ajax and database querying at same time. Now let's build our scene. Open an empty web site and dop a ScriptManager and UpdatePanel from Ajax Extensions tab. Close the tab and open standard controls and drop one textbox and one button. Place a label inside ajax control and one more outside of UpDatePanel. The second label will display that we are using Ajax and page is not posting back. I will add some hard codes and I have put s SqlDataSource and a GridView. Complete code is included
