I'm really struggling to find how to do this with easy to follow VB.NET
samples.

I have built a website with about 4 - 5 content pages using 1 master page.
http://www.openarch.co.uk/default.aspx
The master page contains a menu that loads each of the 4 main pages.
Each page has a variety of controls that are populated from a database.

The problem I am having is with the callbacks.

1 - I don't want the logo and menu (contained in the master) to disapear
each time the page loads
2 - I want to be able to switch images on page with refreshing the entire
page...eg. http://www.openarch.co.uk/ProjectDetails.aspx?ProjectID=1 this
page contains a menu control that is populated with links to images I want
to be able to load images without rereshing anything else on the page.

I have seen lots of references to AJAX but haven't been able to make it work
for me and I'm not sure my ISP has AJAX installed.

None of the starter packs of samples seem to show how to achieve this and
yet it is surely a basic wish of all web designers.

I know a bit of VB.NET and just getting my head around ASP.NET very slowly.

Any help will be appreciated.

OK so I've sort of fiigure out AJAX now and can get the image updates
working OK but still not getting the main menu updates.
 
The following applies if you are using ASP.NET 2.0 (Visual Studio 2005)

I recommend you check to see if your ISP has or will install Microsoft
ASP.NET AJAX 1.0. If you can use it, it will be the simplest way to get the
behavior you want.

For what you describe, you will only need to use one of the ASP.NET AJAX 1.0
controls - the UpdatePanel.

The best resource for downloading and learning to use ASP.NET AJAX 1.0 is
