The PdfViewerAnnotationBuilderExtensions class methods allows you to retrieve options for specific annotation types when the AnnotationCreating event fires.

C#

private void PdfViewer_MarkupAnnotationCreating(object sender, PdfAnnotationCreatingEventArgs e)
{
    if (e.Builder.AnnotationType == PdfAnnotationType.TextMarkup)
    {
      IPdfViewerMarkupAnnotationBuilder builder =
      e.Builder.AsTextMarkupAnnotationBuilder();
      builder.Author = "John Smith";

    }
}

VB.NET

Private Sub PdfViewer_MarkupAnnotationCreating(ByVal sender As Object, ByVal e As PdfAnnotationCreatingEventArgs)
    If e.Builder.AnnotationType = PdfAnnotationType.TextMarkup Then
        Dim builder As IPdfViewerMarkupAnnotationBuilder = e.Builder.AsTextMarkupAnnotationBuilder()
        builder.Author = "John Smith"
    End If
End Sub
