Hello Jonathan Perry,
Thank you for contacting us.
In such case, depending on your need you can either access the rows using the RadGrid object(grdShippedOrders) and accessing the rows by grdShippedOrders.MasterTableView.Items.
Or, beacuse in this example the state is reserved in the session, you can use the ShippedOrders property to get access to all the rows in the shipped table.
Hope this helps.
Kind regards,
Genti
