If you are asking how you redirect to another page without refreshing the whole page: you don't. A new page is a new page. It doesn't matter if it shares identical content as the page before it. If you are under the impression that the master page is
an entity unto itself, to the browser, you are mistaken. Asp.net processes the content page first, then fetches the associated master page and interleaves their lifecycle events (http://msdn.microsoft.com/en-us/library/vstudio/dct97kc3(v=vs.100).aspx ).
The combined result is downloaded to the browser as a single page.
As for UpdatePanels: they give the visual effect of only refreshing part of the page - but that applies to the page they are on. They are not something that has an effect across multiple pages.
If that is not what you are asking, can you explain what you are looking for?
