View State for TextBox and other controls that implement IPostBackDataHandler 2012-01-08

While reading the official training kit for 70-515 exam I came across this text: “With view state, data is stored within controls on a page. For example, if a user types an address into a TextBox and view state is enabled, the address will remain in the TextBox between requests.”. If such statements can be found in recommended study guide, it should not come as a surprise, that confusion about the way ASP.NET Web Forms tries to cope with inherent statelessness of HTTP is so common… ;)

Session access from Page Methods 2008-08-13

ASP.NET AJAX offers easy to use and effective mechanism to invoke methods on the server from JavaScript. It’s called Page Methods. Because those methods are static* you cannot use Page.Session property. This does not mean that you have to give up the use of the session. Simply, you should use the HttpContext.Current.Session instead of Page.Session.
