How to maintain current View active in Multiview

when the DetailsView Insert button is clicked, this code checks to see if there is an email in other records, and if there is, then it cancels and Label1 displays "That Email is already registered".  So far it works.  The only problem is the DetailsView is in View 1 of the Multiview.  After the code executes, View 0 becomes the active view.  I can't figure out how to keep View 1 active?
