A user can open the same page twice or more in a new tab or browser window. Your task may require differentiating between the page instances. In this case, the URL and Session are the same. The solution is to use the ASPxHiddenField component, to store a unique ID of a given page instance.

Hi DevExpress,
This sample works great in web app but how can we use the same technique in web form? We always get a message like 'NewGuid' is not a member of 'guid'.
Thank you,
Sébastien
