If you are talking about changing the Stack on the DetailPage, from a MasterPage navigation link, the best way to do this is with the container and region mapping.
In your TabbedViewContainer, in the constructor, label your Master and Detail pages, as such.
RegionMapping.Add("Master", ContainerType.Master);
RegionMapping.Add("Detail", ContainerType.Detail);
Next, also note the name you assigned your container, e.g.
public TabbedViewContainer(MainStack mainStack, SecondStack secondStack)
: base(Containers.Tabbed.ToString(), null)
Then when you do a navigate, make sure you specify the Container and Region, in this case Containers.Tabbed.ToString()
and "Detail"
, and it will cause the navigation in that particular region.
