I have an aspx page: Main.aspx which has several components that cause
a postback. In the page Main.aspx I also have an iframe which contains
a multi-page pdf file.

The problem I am facing is that whenever the user does an action which
causes a postback on the main page Main.aspx, the page posts back and
the pdf file in the iframe is reloaded. This is a problem becuase if
the user has rotated or magnified the page then that is lost.

Is there anyway that the content in the iframe is not refreshed? Any
other ideas to maintain the state of the pdf file.?

Thanks a lot!

Fred

Did you try using "Page.IsPostBack" Property?

I'd suggest using regular frames instead of an IFrame.
That way each frame posts back independently - one is not embedded within
the other so you won't have this problem.

DHTML behaviors are your friend...given you're in an IE 5.5+ environment.

The way most people would probably do it is to have a frameset with 3 frames
containing: Pagemain, Page1, Page2

Right, but the problem is that my pagemain.aspx has a datalist which
contains hyperlinks. This datalist is my navigation bar. So if someone
clicks on a hyperlink http://server/site/nextpage.aspx, only
pagemain.aspx would navigate to the nextpage.aspx. What I want to do
is to replace the entire frameset with nextpage.aspx. Is there anyway
to do that? Any ideas?

Thanks a lot!

Fred
