Programmatically delete annotation

[iansml]

Hi,

Is there any way I can programmatically remove an annotation? I am able to hide it using:

Code: Select all

imageViewer1.SelectedAnnotation.Visible = false;

but it is still present in the ImageViewer.Annotations collection. I want it to be removed completely (like when I select an annotation and delete it manually using the delete key).

Thanks

Hi Ian,

Thank you for your message. You can use the Remove method of the AnnotationCollection class. Here is an example:

Code: Select all

AnnotationBase annoToRemove = annotationViewer1.Annotations[imageIndex][indexOfAnnoToRemove];
annotationViewer1.Annotations[imageIndex].RemoveAt(annoToRemove);

We will redefine the RemoveAt method of the AnnotationCollection class in next version of library and it will work correctly.

Best regards, Alexander
