Passing Viewstate Data to Popup Window

Question

Hey,

As far as I can tell it is impossible to access the ViewState of a parent page from a popup.

What is the best approach to accomplish passing this information?

I have considered the following:

Using the Session but this may have memory implications on the server.

Passing data in querystring but this may have security implications exposing data and access method in page

Any other ideas or recommendations?

Thanks in advance

Answer 1

You could store the information in a database and then pass the row ID to the popup window in the query string.

Answer 2

Instead of a popup window, you could use a modal overlay (like this: http://malsup.com/jquery/block/#dialog).

Answer 3

You don't want to use Viewstate - as that is tied to the parent page and not meant to be passed around.

You can try passing some info via a querystring that has been encrypted. In a sense, this would be equal to what you were trying to accomplish via passing the viewstate. The viewstate is essentially data encrypted within your page - accessible just the same as the querystring.

You could also use cookies, or session as well. If you have memory concerns with using session, I think storing state in a database would be more advantageous.
