This set of examples shows how to use the placement properties to specify the position of a Popup control.
Example
You can determine the position of a Popup control by using the following properties:
The first four properties define a two-dimensional coordinate on the screen. The fifth property, Placement, positions the Popup and also defines its behavior if its content overlaps the screen boundaries.
Use a PlacementMode enumeration value to set the Placement property. For more information about the enumeration values for PlacementMode, see How to: Set the Placement Property for a Popup or Tooltip.
The following illustrations show how the placement properties work together to position a Popup control.

Popup myPopup = new Popup();
myPopup.PlacementTarget = myEllipse;
myPopup.PlacementRectangle = new Rect(0, 0, 30, 50);
myPopup.VerticalOffset = 20;
myPopup.HorizontalOffset = 20;
myPopup.Placement = PlacementMode.Bottom;
myPopup.PopupAnimation = PopupAnimation.Fade;
myPopup.AllowsTransparency = true;
TextBlock popupText = new TextBlock();
popupText.Background = Brushes.Beige;
popupText.FontSize = 12;
