Finding the position of the caret in a TextBox

Question

I need to know the position of the caret in a TextBox so I can pop up a context menu near it. How do I find its placement (not character index)?

Answer 1

Found this article describing how to do what I need done. Turns out you can set both the PlacementTarget of the textbox and the PlacementRectangle from GetRectFromCharacterIndex and it will work.

Answer 2

Check out this example.
