Hi John,

As I said, my buttons only use Client-side code, no code behind. And as you know, Client-side fires before server side. I don't want to change the design.

Some of the ideas are to try to use XML instead of saving an object in a session and and to try to adjust the pages which are called by these buttons to create DS in them instead of the calling page.

With my colleague I would need to pick up a plan.
