persistent objectdatasource

Hi

It seems every time the grid bound to my objectdatasource refreshes its data
(by calling the select method on the objectdatasource), a new instance of my
object implementing the objectdatasource BL logic is instantiated.

Since my objectdatasource is not SQL bound and only stores data in memory,
this is of no use to me.

I there any way for the objectdatasource to be bound to a specific instance
of the class implementing my business logic (and data storage)

Regards
