Transfer a session in an hyperlink in detailsview with apsx

A session variable is available as long as the session is active...so once you set a session, it is there, you don't need to "pass it" like a querystring variable....are you asking how to set it?

Note: the pages pull from seperate Databases and are linked
actually it works fine as long as i go from page 1 to page 2 (the detail page) first.  in other words if i populate page2  it sets the session and then when i go to page 3 and hyperlink back to page 2 it looks awesome...the problem is sometimes i want to start in page3 and go back to page 2...i have either the wrong sessionvariable or no session variable in place.  maybe what i'm trying to do is reset and set a new session variable at that point...is that possible?

From what I understand..the detailview on page 3 has a hyperlink that goes back to page 2
And if the user didn't go from page 2 to page 3 and back to page 2, you have problems (because they started on page 3 and you set the session on page 2).

If you don't want to use querystring variables....I would suggest instead of using a hyperlink to go from page 3 to page 2, if you use a linkbutton, then in codebehind, you can make sure the session variable in question is set correctly and then response.redirect back to page 2...

i tried that which makes the most sense.

the only problem im having is adding a linkbutton and then getting to the code behind within the detailview.  

can you post the code you have?

the code behind is first then the source code.
all i really need is a way to attach the session variable to a button in the detailsview...
i keep think i'm missing something obvious.
