Hi there,

I am having a problem with my asp.net web pages. If user hit BACK button on
IE and then click some other web controls on the web page. the page goes to
blank page. Anyone has the solution for this?

You'll need to dig into it more and give us more specifics to replicate.

What is the code around line 87 of utility.vb and 417 of get_price.aspx?

I guess that when navigating along a normal flow your page is getting
certain data, but when going "back|" it isn't so some error is happening.
Can't you just step through your code line by line to see what is happening
when you go "back" and how it differs from normal?

Dealing with the Back button

I can't believe this is such an impossibility... I have an asp.net page. It accepts data through on form fields and includes a submit button. The page loads up and you fill out some stuff. The submit button posts the page back to the server. The button code detects an entry error and sends the page back to the user. This all works.
