Use the attached pdf document and launch the PdfPrintPreviewDialog. As it is demonstrated in the gif file, the preview dialog moves the pages slower than the pdf viewer itself.
Expected behavior: the performance for navigating the pages should be at least identical.
This is the result with R3 2022:
This is the result with R2 2023 SP1:
Load a document with bookmarks and select the bookmarks options. Then, move the splitter:
Expected: the selected option (bookmarks) is unchanged
Actual: the selected option (bookmarks) is not preserved and it is reset
When creating many instances of RadPdfViewer:
static void Main(string[] args)
{
int i = 1;
try
{
Stopwatch stopwatch = Stopwatch.StartNew();
while (true)
{
using (RadPdfViewer pdfViewer = new RadPdfViewer())
{
}
Console.WriteLine($"iteration {i}, elapsed seconds: {stopwatch.Elapsed.TotalSeconds}");
i++;
}
}
catch (Exception e)
{
Console.WriteLine($"Exception occurred at iteration {i}");
Console.WriteLine(e);
Console.ReadLine();
}
}the following error occurs:
System.Runtime.InteropServices.ExternalException (0x80004005): A generic error occurred in GDI+. at System.Drawing.Bitmap.GetHicon() at Telerik.WinControls.PdfViewer.MouseHandlers.PanHandler..ctor(MouseHandlersController controller, IFixedDocumentPresenter presenter) at Telerik.WinControls.PdfViewer.MouseHandlers.MouseHandlersController.BuildHandlers(IFixedDocumentPresenter presenter) at Telerik.WinControls.PdfViewer.MouseHandlers.MouseHandlersController..ctor(IFixedDocumentPresenter presenter) at Telerik.WinControls.UI.RadPdfViewerElement..ctor() at Telerik.WinControls.UI.RadPdfViewer.CreateViewerElement() at Telerik.WinControls.UI.RadPdfViewer.CreateChildItems(RadElement parent) at Telerik.WinControls.RadControl.Telerik.WinControls.IComponentTreeHandler.CreateChildItems(RadElement parent) at Telerik.WinControls.RadElementTree.InitializeRootElement() at Telerik.WinControls.RadControl.Construct() at Telerik.WinControls.RadControl..ctor() at Telerik.WinControls.UI.RadPdfViewer..ctor()
Handled InvalidDataException occurs while Zip Library tries to decompress wrongly decrypted stream.
It seems that this is a regression in R1 2023 SP1 after addressing this item:
Open the Demo application >> Interactive Forms example and apply the Office2019Dark theme. You will notice that if the text field enters edit mode, it is difficult to read the input due to black fore color and black backcolor:
Run the project and load a document with bookmarks. Try to click the two buttons in order to switch between thumbnails/bookmarks.
private void radButton1_Click(object sender, EventArgs e)
{
this.radPdfViewer1.ShowThumbnails();
}
private void radButton2_Click(object sender, EventArgs e)
{
this.radPdfViewer1.ShowBookmarks();
}Expected: clicking the two buttons should switch between bookmarks/thumbnails
Actual: the user is stuck to bookmarks
When exporting a RadFixedDocument, which contains a signature added with PdfProcessing a NotSupportedException is thrown: 'Stream does not support reading.'
Resolution: When exporting a digitally signed document a stream that allows both reading and writing should be passed to the PdfFormatProvider.
Example:
Stream outputStream = new FileStream("path", FileMode.OpenOrCreate, FileAccess.ReadWrite)
public TestRadForm()
{
InitializeComponent();
this.radPdfViewer1.LoadDocument(@"..\..\..\SampleDocument.pdf");
}
private void radButton1_Click(object sender, EventArgs e)
{
this.radPdfViewer1.Document.AcroForm.FlattenFormFields();
this.radPdfViewer1.SaveDocument(@"..\..\saved.pdf");
}
