The current page changes too late, almost when the whole page is out of the view. This behavior is wrong making the page number showing the previous page when actually a new one is in the view. It should change when the second page visible height is higher than the current page visible height.

When the user makes the pinch gesture the expected behavior would be for the zoomed point to be the touch position, but it is instead the top left corner of the page.

WPF allows running multiple UI threads in a single process. When RadPdfViewer is used in such scenarios, sometimes InvalidOperationException: 'The calling thread cannot access this object because a different thread owns it.' is thrown. 

Scenarios:
- Show Find dialog (or any other of the dialogs available for register in ExtensibilityManager class) for the first instance, the for the second instance.

The exception is thrown with the message "Password is not correct" even when the user password is correct. This issue occurs for specific encryption algorithm parameters only.

Item is declined because this functionality is not supported and has a logged feature request to support it.

By specification, when some of the destination parameters have null value, the current value of that parameter is to be retained unchanged (This rule applies for most of the properties). For example, if Location (XYZ) destination is imported and any of the left, top, or zoom parameters is null, the current value of the visual viewport for the specified property should be retained. 

Workaround: Edit the document destinations and set default values. For example if the document contains Location destinations the Left, Top and Zoom properties can be set:
foreach (var annotation in document.Annotations)
{
    Link link = annotation as Link;
    if (annotation != null)
    {
        if (link.Destination is Location location)
        {
            location.Left = location.Left != null ? location.Left : 0;
            location.Top = location.Top != null ? location.Top : 0;
            location.Zoom = location.Zoom != null ? location.Zoom : 1;
        }
    }
}

Customers are reporting an issue when trying to copy content in an application hosted on a remote machine (there are reports using TigerVNC and Citrix).  The exception is thrown from the Clipboard class with a message: OpenClipboard failed (Exception from HRESULT: 0x800401D0 (CLIPBRD_E_CANT_OPEN)).

It seems like such a behavior could be reproduced when the clipboard is already opened by another application. Here is a discussion on the matter: https://stackoverflow.com/questions/68666/clipbrd-e-cant-open-error-when-setting-the-clipboard-from-net

Fix available in LIB Version 2018.3.1029.

When the file has an annotation with a destination and this destination is missing from the destinations (Dests) collection of the catalogue, KeyNotFoundException is thrown when you try to scroll to the page where the annotation is located. A better behavior would be for nothing to happen when trying to click on the annotation leading to the destination.

The hierarchical document structure is a means to describe the PDF document structure, which is currently not supported. See 10.6.1 Structure Hierarchy on 856 page of the PDF specification for details.
This document structure is an alternative to the standard PDF structure and most non-Adobe software does not support it.

The document might have been created with Adobe software like Adobe LiveCycle Designer. Very often the document contains some fallback text in the standard PDF structure like:
"Please wait... If this message is not eventually replaced by the proper contents of the document, your PDF viewer may not be able to display this type of document."
"The document you are trying to load requires Adobe Reader 8 or higher. You may not have the Adobe Reader installed or your viewing environment may not be properly configured to use Adobe Reader. For information on how to install Adobe Reader and configure your viewing environment please see  http://www.adobe.com/go/pdf_forms_configure."
"For the best experience, open this PDF portfolio in Acrobat X, Reader X, or later."

Add UI for adding comments and ability to save them. Comments are represented in the document model as text annotations (annotations with Subtype Text).
