If I understand you correctly, you've just ruled out the only 2
possibilities you have. Think about it. The data to populate the combo boxes
is stored on the server. Therefore, you either have to (1) pass it all to
the client to avoid having to PostBack, or (2) PostBack to get the data. If
you can think of a third way, you're probably due the Nobel Prize!

Hi,
I have an ASP.NET form that includes several combo Boxes.
The first Combo is loaded with items on Page_load.
The second depends on the item selected on the first, the third on the
second and so on.
I don't want to transfer all the data needed with the form and also want
to avoid page refresh on every item change.
What is the best method for doing this?
I heard about xmlhttp and WS but I don't know if any of those technologies
is appropriate and how to use them in the project.
Samples will help me very much.
