' Place the slider in the adorner panel.
Dim placement As New AdornerPlacementCollection()
AdornerPanel.SetHorizontalStretch(skewSlider, AdornerStretch.Stretch)
AdornerPanel.SetVerticalStretch(skewSlider, AdornerStretch.None)

' Use layout space for the adorner panel.
' If render space were used, the slider would skew along with the button.
panel.CoordinateSpace = AdornerCoordinateSpaces.Layout

' The adorner's width is relative to the content.
' The slider extends half the width of the control it adorns.
placement.SizeRelativeToContentWidth(0.5, 0)

' Center the adorner within the control.
placement.PositionRelativeToAdornerWidth(0.5, 0)

' The adorner's height is the same as the slider's.
placement.SizeRelativeToAdornerDesiredHeight(1.0, 0)

' Position the adorner within the control it adorns.
placement.PositionRelativeToAdornerHeight(1.0, 0)

// Place the slider in the adorner panel.
AdornerPlacementCollection placement = new AdornerPlacementCollection();
AdornerPanel.SetHorizontalStretch(skewSlider, AdornerStretch.Stretch);
