Because I do not have time to write a documentation I added a small video that will show you how to use the AJAX .NET Wrapper DLL. First I will show the old way using postbacks to the Server. Two textboxes (username and password) will be verified on the server. If the username is not michael and the password is wrong I will show a error message. Please note that every click on the Login button will start a postback (server round trip).
