Managing Browser History in AJAX-style Web pages - .Net way

In one of my project we encountered a problem on utilizing the browser history performed by the user on .Net pages. since we used the updatepanels for updating some parts of the page, this will not trigger the browser to record the change in its history collection.

For example, a user visits Page A and updates some parts in the page A using the partial update(update panels). Now if he refreshes the page, he will lose the changes he had done in the partial update in Page A.

.Net3.5 and ScriptManager gives us a very elegant way to handle this kind of situations even for navigation through browser's NEXT and PREVIOUS buttons.

Base Class Usage Guidelines

This is our initiative to share the technical details of our discussion and to provide other useful technical details / references for the group.


As a starter thought this would be a good look for basic guidelines about usage of Base classes, interfaces and sealed class.
