Answer 1

Window.Left and Window.Top

var location = myTextBlock.PointToScreen(new Point(0,0));
window.Left = location.X;
window.Top = location.Y-window.Height;

Answer 2

You would need to get the coordinates of the hyperlink and then set the window position as shown here:

Answer 3

You need to set the WindowStartupLocation to Manual (which is the default however) as well as setting the Top and Left property values.

Setting CenterScreen causes a window to be positioned in the center of the screen that contains the mouse cursor.

Setting WindowStartupLocation to CenterOwner causes a window to be positioned in the center of its owner window (see Owner), if specified. The owner window can be either another WPF window or a non-WPF window.
