Hi Sergey,
Thank you for your update,
Query#1: It would be good if the thickness and brush of the border could be set via style of DockedElementTabbedHost.
We have prepared a sample that tries to meet your requirement. In our sample, we have changed the BorderThickness and BorderBrush for the border in the container of hosted element using DockedElementTabbedHostStyle. Please download the sample from the attachment:
Query#2: The Remarks section of the description of DockedElementTabbedHost class, says: "You can use DockedElementTabbedHost class when you need to show tabs in the element. When there is no need to show tabs in the element you have to use DockedElementTabbedHost class."
DockedElementTabbedHost can be used in both scenarios. Internal TabControl will be created when it is required to show tabs and will be hidden when it is not required to show tabs.
Regards,
Vijayalakshmi V.R.
