Hi Mohamed, 

Thank you for contacting Syncfusion support. 

We can select and change the properties of the annotation from the code behind using the PDF Viewer API. We have created the sample for the same and shared in the below link,

In the above sample draw an annotation and click on “Select Annotation” button.
