There are several ways to do this. For example, just create a session variable, then assign the value to the session variable. You can access this session variable throughout the session's life cycle.

Or, if you needed long term storage of information, it could be written to a database table, or even a cookie on the user's computer.

example:

first, create a session and assign a value.

Session("example") = txtExample.text

and then if you want to retrieve it from another page, do something like this:

lblExample2.Text = Session("example").ToString()
