Most PDF viewers have option (enabled by default) which allows fields to be highlighted with colors predefined in the settings. Required fields are highlighted using different color.

For example: In Adobe Acrobat Reader DC this is enabled in "Edit" -> "Preferences" -> "Forms" -> "Highlight Color" -> "Show border hover color for fields".

Hyperlinks within a document are not working via touch. They are working only when a mouse is used.

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.

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;
        }
    }
}

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.

This happens only in specific scenarios as most of the documents with annotations are visualized correctly.

This is not quite a valid PDF file scenario according to PDF file specification. However, we may try handling it in order to show the correct number of pages. When the kid is of type Pages, it should be added to the pages traversal recursion only the first time it is met.

Default RadPdfViewer presenters load image sources async which allows to render the rest PDF content faster. However, FixedDocumentSinglePagePresenter loads images syncrhonously and all page content is rendered right after all images on the page are loaded.

Setting DocumentSource throws NullReferenceException when PdfViewer is hosted in ElementHost. When setting the DocumentSource, the Application.Dispatcher is used, but in Winforms app, the Application is not instantiated. 

Steps to reproduce:
1. Host PdfViewer in ElementHost in a WinForms application
2. Set the DocumentSource property
3. Run
Expected: The document is opened
Actual: NullReferenceException is thrown

Workaround: the document could be set to the Document property of PdfViewer. Or instead hosting the PdfViewer for WPF in ElementHost, use WinForms version of the control.
