I have 2 private variables in my class that I need to remember the values of
between postbacks (or actually callbacks, since I am using AJAX). I want to
avoid using session variables, if possible. Is there any other way to have
VB.NET maintain the values of these variables between postbacks & callbacks?
Thanks.

Eliyahu,
Is this not putting the horse behind the car, using ajax and then send the
variables over the line?
This is more ment for Nathan than for you.

I'd suggest you use ViewState in this situation.
Here are some other options, though: http://SteveOrr.net/articles/PassData.aspx

I think the OP has to state clearly whether he is planning on postbacks or
callbacks. ViewState is obviously good for postbacks. This thread may help
for ViewState between callbacks: http://forums.asp.net/p/1128218/1781727.aspx#1781727

We're trying to determine how to deal with password fields losing their

when they submit. Here's an illustration:
