pass data from page to page

[Guest]

Is there a way to pass data from page to page without the use of a Session
Variable or queryString?
I need to pass drop down box selections from page to page and have the drop
downs on the page be the same as they were on the page the user is coming
from. I'm using a master page and a sitemap file for my menu.

example:
If I'm in page 1 and I select
BMW in dropdown 1 and 535 in drop down 2
if i select a new page on the menu, the drop downs on that page needs to
have selected BMW (since that drowndown data is on that page as well.)

what is the best way to do this?

You can also set a cookie. Sometimes this works nicely as the session
management can be a drain on the server whereas the cookie will just be on
the client. Of course, the user may not have their browser to accept
cookies, but that would also provide issues for the session as well since
the id is stored in a cookie unless explicitely using cookieless sessions.

The cookies may be the easiest since they work well with more than ust
ASP.Net and they're pretty lightweight as far as server resources.

hejdig.

Normal posting?

You could program with client side controls.
<form target="otherpage.aspx" method="post">
<select name="ddlCar"><option....
</form>
and on otherpage.aspx.cs
string carID = Request[ "ddlCar" ];

Something like that. I don't have the exact attribute and method names in
my head. Google for ASP solutions.

You can investigate the features of asp.net 2 that allow pages to post to
other pages. You can also check out the profile object.

Though i'm curious -- why don't you want to use Sessions?

Hi,

In following MSDN documentation:

#How to: Pass Values Between ASP.NET Web Pages
http://msdn2.microsoft.com/en-us/library/6c3yckfw(vs.80).aspx

Besides query string and session state, you can use cross-page posting:

#Cross-Page Posting in ASP.NET Web Pages
http://msdn2.microsoft.com/en-us/library/ms178139(VS.80).aspx


or use HttpServerUtility.Transfer():

#HttpServerUtility.Transfer Method (String) (System.Web)
http://msdn2.microsoft.com/en-us/library/y4k58xk7(VS.80).aspx
The Transfer method preserves the QueryString and Form collections.
