Download the attached pdf document and open it with RadPDfViewer and Adobe Reader. You will see that our viewer renders it with the black and white colors inverted.

Add two additional buttons in the RadPdfViewerNavigator like in Adobe Reader:
- The first one must fill the window with each page and scroll through pages continuously. 
- The second one must show one page at a time.

Workaround: print the document page by page:
private void radButton1_Click(object sender, EventArgs e)
{
    RadPrintDocument d = new RadPrintDocument();
    d.PrinterSettings.PrintRange = PrintRange.CurrentPage;
    d.AssociatedObject = this.radPdfViewer1;
    for (int i = 0; i < this.radPdfViewer1.Document.Pages.Count; i++)
    {
        d.CurrentPage = i;
        d.Print();
    }
}

Open large file in RadPDFViewer. Navigate from page 70 to page 250 or enter number by hand and you will notice that the page is opened slowly.

To reproduce:
Open the attached document. You will see that it will be rendered blank due to the NotSupportedException

Resolution: 
This is an unsupported font from our engine. In debug the SL PDF also throw this exception, since the engine does not support this font type. WinForms PDF rendered this documents with delay.

PdfViewer - throws NullReferenceException in GetPages method of PdfContentManager.

To reproduce:
- Just show and close a form that contains pdf viewer with a loaded document several times. 

To reproduce:
- Load a pdf file at the constructor and try to load another pdf file on Form.Load => the result is that the second pdf is not loaded.
 public Form1()
        {
            InitializeComponent();
            radPdfViewer1.LoadDocument("..\\..\\pdfSample.pdf");

        }

        private void Form1_Load(object sender, EventArgs e)
        {
            radPdfViewer1.LoadDocument("..\\..\\test.pdf");
        }

Workaround: unload the first loaded document prior loading the second one

ADD. RadPdfViewer - add ability to show the document pages as thumbnails

Add rotate view button.

To reproduce: 
1. Drag and drop RadPdfViewer and RadPdfViewerNavigator
2. Load attached file from ticket
3. Click PrintPreview button from navigator and you will see that NullRefference exception is thrown. 

Workaround: 
You can set the ShowPrintPreview property to false of RadPrintViewNavigator
this.radPdfViewerNavigator1.ShowPrintPreview = false;
