Hi Bernd,
Thank you for using Syncfusion products.
Could you please clarify your requirement of retrieving the caret position is based on?
1. Coordinate within SfRichTextBoxAdv control
2. Coordinate within application window
3. Coordinate of entire screen
If possible, please provide prototype sample by specifying default position (Instead of caret position) for context menu. So that we can analyze further with respect to your requirement and provide you appropriate solution at the earliest.
Regards,
Venkatesan.
