Re: Unable to get BringToBackItemUIAction UIAction to work

Hi Harlan,
However I am using the annotation tool FindAnnotationView method to select the annotation on a mouse event.
Please override the PdfAnnotationTool.FindInteractiveObject method and implement logic similar to the logic in PdfAnnotationTool.CanInteractWith method.

Best regards, Alexander
