Pdf Viewer Crashes when resizing my app

[Ali]

Hi,

I didn't get this problem but i get it now

My SfPdfViewer version is 15.4

My Code:

public StorageFile PdfLoadableDoc { get; set; }

//My Page Constructor

        public PdfViewer(StorageFile PdfFile)
        {
            this.InitializeComponent();

            PdfLoadableDoc = PdfFile;
        }
        private async void Page_Loaded(object sender, RoutedEventArgs e)
        {
            var stream = await PdfLoadableDoc.OpenAsync(Windows.Storage.FileAccessMode.Read);
            Stream fileStream = stream.AsStreamForRead();
            byte[] buffer = new byte[fileStream.Length];
            fileStream.Read(buffer, 0, buffer.Length);
            //Loads the PDF document.
            PdfLoadedDocument loadedDocument = new PdfLoadedDocument(buffer);
            pdfViewer.LoadDocument(loadedDocument:loadedDocument);
           

            pdfViewer.ShowPageNumber = false;
            pdfViewer.TextSelectionSettings.SelectionColor = Windows.UI.Color.FromArgb(60, 84, 110, 122);
            pdfViewer.PdfProgressRing.Foreground = new SolidColorBrush(Windows.UI.Color.FromArgb(100, 84, 110, 122));
            pdfViewer.HighlightAnnotationSettings.Color = Windows.UI.Color.FromArgb(100, 118, 255, 3);
            pdfViewer.UnderlineAnnotationSettings.Color = Windows.UI.Color.FromArgb(100, 255, 61, 0);
            pdfViewer.PopupAnnotationSettings.Color = Windows.UI.Colors.LightBlue;
            txt_DocPages.Text = pdfViewer.PageCount.ToString();
            RightMenuOpenHeight = 0;
            RightMenuExtendedHeight = 265;

            if (Fit)
            {
                pdfViewer.ViewMode = PageViewMode.FitWidth;
            }

            LoadNavigator(pdfViewer.LoadedDocument);

}

My Xaml:

<syncfusion:SfPdfViewerControl x:Name="pdfViewer" IsTextSearchEnabled="True" ShowPageNumber="False" ItemsSource="{Binding DocumentStream}" ScrollChanged="pdfViewer_ScrollChanged" PageChanged="pdfViewer_PageChanged" ZoomChanged="pdfViewer_ZoomChanged" KeyDown="pdfViewer_KeyDown" />

Error:
