How can I set the SelectedIndex in a Panorama control? or force a navigation to a specific item?
Panorama is designed so the user is in control, there fore you can not set SelectedIndex programmatically, or force a navigation to a panorama item.
You can set the DefaultItem so that when your panorama is first launched, the panorama navigates to that item, but you can’t navigate programmatically beyond that. DefaultItem can also be used so that a back navigation feels like the item where the user was at did not change.
