To change the Attached Properties values ββin Setter.Target use this format:
TargetObjectXName.(ClassName.AttachedPropertyName)
In your case:
<VisualState.Setters> <Setter Target="TimestablesControl.(RelativePanel.RightOf)" Value="Control1"/> <Setter Target="TimestablesControl.(RelativePanel.AlignRightWithPanel)" Value="False"/> <Setter Target="TimestablesControl.(RelativePanel.AlignLeftWithPanel)" Value="True"/> </VisualState.Setters>
Where "Control1" is x: the name of the control you want to place to the left of TimestablesControl.
