When importing a document containing a single associated widget annotation merged into the field dictionary the field is skipped on import and an exception is thrown.

According to the PDF Specification: Field Dictionaries: Kids:

An array of indirect references to the immediate children of this field.
In a non-terminal field, the Kids array is required to refer to field dictionaries that are immediate descendants of this field. In a terminal field, the Kids array ordinarily must refer to one or more separate widget annotations that are associated with this field. However, if there is only one associated widget annotation, and its contents have been merged into the field dictionary, Kids must be omitted.

Hi,

The RadPdfViewer ExportPages is broken in the new release. It works in the previous version.

The viewer is using a large amount of memory when scrolling a specific PDF file. After some point, an OutOfMemeory exception is thrown.

Workaround:

Build for the x64 platform

PdfViewer: Password protected documents cannot be opened 

Workaround:

PdfFormatProvider provider = new PdfFormatProvider();
PdfImportSettings settings = this.radPdfViewer1.PdfViewerElement.ImportSettings;
settings.UserPasswordNeeded += (s, a) =>
{
    a.Password = "1234";
};

provider.ImportSettings = settings;

this.radPdfViewer1.LoadDocument(@"..\..\password.pdf");

Is there a way to load this RadFixedDocument into a RadPdfViewer without writing the document to a file first and then loading it in the viewer?

Workaround:

You can achieve the desired functionality by exporting the RadFixedDocument to a MemoryStream instead of a file in the file system and then load it in the PdfViewer: 

RadFixedDocument document = CreateRadFixedDocument();

PdfFormatProvider pdfFormatProvider = new PdfFormatProvider();
Stream ms = new MemoryStream();
pdfFormatProvider.Export(document, ms);

radPdfViewer1.LoadDocument(ms);

Hello,

When opening this document (see attached), PDF viewer crashes with following exception.

Good morning.

I'm using a pdfViewer instance in order to load pdf forms, with text fields to be edited by the users.

Loading is ok, editing is ok, the problem is when I go to save the edited document. When I save the document, if I don't click elsewhere in the document, in which case the content of the field is committed, the content of the field is not saved with the document. This happens either using the 'Save As' button or using the SaveDocument API function.

Probably it is my fault, since I'm new to PdfViewer: I can imagine that something like a commit command has to be available, but I'm not able to find it.

Can you help me, please?
Thank you in advance.

PS. I will attach three screenshots in order to let you understand better what I mean.
