Customizing progress ring in UWP Pdf Viewer (SfPdfViewer)

The following code illustrates the design of the progress ring in red color foreground with dimension of 100x100. Here ‘buffer’ is the byte array read from the PDF file either using FileOpenPicker or from Assets folder, as illustrated in the Viewing PDF section.

PdfLoadedDocument loadedDocument = new PdfLoadedDocument(buffer);
pdfViewer.LoadDocument(loadedDocument);
//Creates custom progress ring.
ProgressRing progressRing = new ProgressRing();
progressRing.Foreground = new SolidColorBrush(Windows.UI.Color.FromArgb(255, 255, 0, 0));
progressRing.Width = 100;
progressRing.Height = 100;
//Assigns custom progress ring to the Viewer control.
pdfViewer.PdfProgressRing = progressRing;
Dim loadedDocument As New PdfLoadedDocument(Buffer)
pdfViewer.LoadDocument(loadedDocument)
'Creates custom progress ring.
Dim progressRing As New ProgressRing()
progressRing.Foreground = New SolidColorBrush(Windows.UI.Color.FromArgb(255, 255, 0, 0))
progressRing.Width = 100
progressRing.Height = 100
'Assigns custom progress ring to the Viewer control.
pdfViewer.PdfProgressRing = progressRing
