hi, Brad
Thank you posting your question here.
We actually have a detail example showing how to do that. Please see this link:
http://www.essentialobjects.com/ViewDoc.aspx?t=TabStrip%2fcreate_tabbed_dialog.htmlThe key is to set MultiPageID of the TabStrip to your MultiPage Control's ID, and make sure Multipage control is right below the TabStrip control, every PageView should be displayed right below the TabStrip control.
If you still have problem, please let us know.
Thanks.
