Hello everyone. I am in middle of implementing AutoComplete for a RichTextBox. Unfortunately, I have hit a snag in my line. I cannot seem to find a way to get the XY coordinates of the caret. I need this because I want to make the autocomplete window show up next to the caret.

I have been googling for the last two days. All of the results talk about the TextPointer and is not what I need.

EDIT: If it helps, this is my latest attempt.

//thw is the autocomplete window and box is the richtextbox.
thw.WindowStartupLocation = System.Windows.WindowStartupLocation.Manual;
                    Rect bounds = box.CaretPosition.GetCharacterRect(LogicalDirection.Forward);
                    thw.Top = bounds.Y + box.Margin.Top + win.Top;
                    thw.Left = bounds.X + box.Margin.Left + win.Left;
                    thw.Show();

Well if your box variable is the RichTextBox then I couldn't find CaretPosition in intellisense. You should use box.GetPositionFromCharIndex(index); where index is the index of the char that you currently have. I'm not exactly sure how you would get the index but if I find out I will update this post with the how-to.

EDIT: I saw this but ignored it. Use int index = box.SelectionStar;. It does what the property says but if there is no selection then it gets the position of the caret as an offset from the beginning of the richTextBox. Good luck

Thanks for the speedy reply, but you are thinking about the Winforms RichTextBox. I am using the WPF RichTextBox.

We have a WPF forum for this exact reason.

Heh, I thought that was for XAML. My problem is using actual code.

Thank you for moving it though.

Sorry I didn't know . I don't know much about WPF so the only thing I could find is an article on stackoverflow which is here and it looks like you have already tried it: http://stackoverflow...wpf-richtextbox
