Answer 1

I think your concept of session is wrong. Session is a server-side object, and javascript runs on the client, so you can not directly assign that value to a session. You can, instead, use some AJAX to send it to the server and then add code in the server so the value is assigned.

Answer 2

Hm... you have to think about the difference between serverside and clientside first... You cant directly access changes you made in the client on the serverside, because you once send a request to server, as a response you get the site diplayed in your browser. As soon as you recieve the request, the server is finished and cant access the site anymore. Its like a letter you send away. As soon as you put it into the mailbox, you cant make changes anymore. But you could post a new request to the server and add POST or GET peremeters. These can be accessed by the server. The way you send the request doesnt matter... you can send a request using AJAX or simply reload the page.

If your Form1.aspx submits to Form2.aspx, then you have atleast a few ways to access the value of form fields (including Hidden fields):

• The Request.Form property exposes a NameValueCollection containing all submitted form field names as Keys and their values as Values. You could use the syntax Request.Form["fieldName"] to access the value.

• If this is ASP.NET 2+ and you used the Cross-page posting technique, you will be able to access field values in the previous page using the PreviousPage property of the Page.

• If you use Server.Transfer, you can access values using the Current HttpContext.

If you need more info, you should take a look at Passing values between pages in ASP.NET.
