Answer 1

I found a solution to use the screen size
'stp is the stackpanel

Dim bounds As New Rect
 Dim scaleFactor As Double
 Dim size1 As Size
 bounds = ApplicationView.GetForCurrentView().VisibleBounds
 scaleFactor = DisplayInformation.GetForCurrentView().RawPixelsPerViewPixel
 size1 = New Size(bounds.Width * scaleFactor, bounds.Height * scaleFactor)
 stp.Height = size1.Height * 0.8 / scaleFactor
