In one of our apps, we have the ability to comsume our website through Windows Forms and open our website in a Windows WebBroswer control. Everything works great until one of the links opens a new window for printing. We were doing something similar to
window.open('someurl', ....);
The problem is, the new window loaded the page using content stored in our session variables. The new window started a new instance of IE (or whatever the default browser is set to) and therefore created a new session for the page. Scouring the Internets lists some ways to share the session via storing session in the database. This just wasn't feasible for several reasons
- The performance hit we take by storing variables in session rather than inproc
- Having to mark all of those objects as serializable
- A lot of work for something simple like getting the print button to work
The solution is to change how we are opening the new window to be a modal dialog
window.showModalDialog('someUrl', ....);
Using a modal dialog we still share the session with the parent page. You may encounter some styling issues, but all in all, a lot better than changing where your session is stored and all the headaches involved in that.
