WPF TextBox obtain and set caret position from mouse pointer

Question

I am trying to set TextBox caret position according to the mouse coordinates when hovering over the TextBox. I can obtain the mouse coordinates relative to the TextBox by using Mouse.GetPosition(this.MyTextBox) but I need help translating those coordinates into the caret position. Any help would be greatly appreciated!

I think you should try simulating mouse click event in you TextBox and pass the mouse position as event arguments — , May 15 '12 at 23:06

MyTextBox.CaptureMouse();
MyTextBox.CaretIndex = MyTextBox.GetCharacterIndexFromPoint(Mouse.GetPosition(MyTextBox), true);
