Getting Text and Location of annotations of a page

[Ric Silva]

i have this code to add annotations to a pdf page

                    ....
                    var page = pdfDocument.Pages[pagn];
                    ....
                    string pdfAnnotationMsg = "Test Annotation 123";
                    PdfPopupAnnotation popupAnnotation = new PdfPopupAnnotation(new RectangleF((float)x, (pageHeight * 1.325f) - (float)y - VertOff2, 5, 5), pdfAnnotationMsg);
                    popupAnnotation.Border.Width = 1;
                    popupAnnotation.Open = false;
                    popupAnnotation.Border.HorizontalRadius = 1;
                    popupAnnotation.Border.VerticalRadius = 1;
                    popupAnnotation.Icon = PdfPopupIcon.Comment;
                    page.Annotations.Add(popupAnnotation);

the annotation gets added correctly but now im trying to access to its content and location 

i have this variable :

PdfLoadedAnnotationCollection annotationCollection = pdfDocument.Pages[0].Annotations;

and its count number shows the correct ammount of annotations, but if i use

annotationCollection[0].Text

i get a exception:

"A first chance exception of type 'System.NullReferenceException' occurred in Syncfusion.Pdf.WinRT.DLL"

how do i properly get the Text and Location from the diferent Annotations ?

ok i solved the problem some how eheh

i was loading the file to the viewer this way 

pdfViewer.DocumentLoaded += (sender, e) =>

                {

                    try

                    {

                        pdfViewer.ViewMode = PageViewMode.FitWidth;

                    }

                    catch (Exception e1)

                    {

                        Debug.WriteLine(e1.Message);

                    }

                };

                pdfViewer.LoadDocument(pdfDocument);

i replaced it with:

pdfViewer.LoadDocument(pdfDocument);

pdfViewer.ViewMode = PageViewMode.FitWidth;

and for some reason my annotation code started working
