Is it possible to do ?

We can delete all the annotations using deleteAnnotations method. Please refer to the below code snippet and sample,

Code Snippet:

<button @onclick="delete">Delete Annotations</button>

private void delete()

{

PDFViewer.DeleteAnnotations();

}

Sample: https://www.syncfusion.com/downloads/support/directtrac/general/ze/TestApp-1330679931

And I import annotation with this line : await Viewer.ImportAnnotation(selectedProp.AnnotationFileName, AnnotationDataFormat.Json);

Is there an other way programmaticaly ?

We don’t have other options to add all the annotations programmatically in our PDF Viewer. We can only add the annotations programmatically using ImportAnnotation method.

Please let us know if you have any concerns,

Regards,

Vasugi
