Wrong statement

- EndPrint – Event fired when the printing is either completed or cancelled. The EndPrint isn't fired when clicking CANCEL on the Print Dialog

@Apoorv: remove debug breakpoints from btnPrint_Click and printpage event handler, this is a "timing" problem (.NET refuses request after some wait time).

Everyone on the 'net doesn't see the RTW object model for PrintDocument:

No more DocumentName property, it's a param to the Print method now.

Plus new BeginPrint

namespace System.Windows.Printing
{
    // Summary:
    //     Provides printing capabilities for a Silverlight application.
    public class PrintDocument : DependencyObject
    {
        // Summary:
        //     Gets the identifier for the System.Windows.Printing.PrintDocument.PrintedPageCount
        //     dependency property.
        //
        // Returns:
        //     The identifier for the System.Windows.Printing.PrintDocument.PrintedPageCount
        //     dependency property.
        public static readonly DependencyProperty PrintedPageCountProperty;

        // Summary:
        //     Initializes a new instance of the System.Windows.Printing.PrintDocument class.
        public PrintDocument();

        // Summary:
        //     Gets the number of pages that have printed.
        //
        // Returns:
        //     The number of pages that have printed.
        public int PrintedPageCount { get; }

        // Summary:
        //     Occurs after the System.Windows.Printing.PrintDocument.Print() method is
        //     called and the print dialog box successfully returns, but before the System.Windows.Printing.PrintDocument.PrintPage
        //     event is raised.
        public event EventHandler BeginPrint;
        //
        // Summary:
        //     Occurs when the printing operation is complete or when the print operation
        //     is cancelled by the application author.
        public event EventHandler EndPrint;
        //
        // Summary:
        //     Occurs when each page is printing.
        public event EventHandler PrintPage;

        // Summary:
        //     Starts the printing process for the specified document by opening the print
        //     dialog box.
        //
        // Parameters:
        //   documentName:
        //     The name of the document to print.
        //
        // Exceptions:
        //   System.Security.SecurityException:
        //     The print operation is not user-initiated.
        [SecuritySafeCritical]
        public void Print(string documentName);
    }
}

What appen if the user just press "Cancel" in the dialogbox of print, because to me it's not working...
