Print on PDF Viewer hard time

[figueiredorj]

Hi.

I am having a hard time on how to make PDF viewer print. 
I am using telerik toolbar from demo with options defined their an all is working ok except to print.

Can someone give me hint on what can be the issue?
My code is something like:
XAML:

<telerik:RadWindow x:Class="DoisSoft.TTrack.ReportWindow"

    </Grid>
</telerik:RadWindow>

and on code-behind:

public partial class ReportWindow : RadWindow, INotifyPropertyChanged
   {
       private byte[] _document;
       private IEventAggregator _eventAgrregator;

       public byte[] Document
       {
           get { return _document; }
           set
           {
               if(_document != value)
               {
                   _document = value;
                   OnPropertyChanged("Document");
               }
           }
       }

       public ReportWindow(IEventAggregator eventAggregator)
       {
           InitializeComponent();
           _eventAgrregator = eventAggregator;
           this.DataContext = this;
       }

       private void pdfViewer_Loaded(object sender, System.Windows.RoutedEventArgs e)
       {
           _eventAgrregator.GetEvent<BusyLoadingEvent>().Publish(false);
       }

       private void tbCurrentPage_KeyDown(object sender, System.Windows.Input.KeyEventArgs e)
       {
           TextBox textBox = sender as TextBox;
           if (textBox != null)
           {
               if (e.Key == System.Windows.Input.Key.Enter)
               {
                   textBox.GetBindingExpression(TextBox.TextProperty).UpdateSource();
               }
           }
       }


       #region INotifyPropertyChanged Members

       public event PropertyChangedEventHandler PropertyChanged;
       protected void OnPropertyChanged(string propertyName)
       {
           if (this.PropertyChanged != null)
           {
               this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
           }
       }

       #endregion

       private void RadButton_Click(object sender, System.Windows.RoutedEventArgs e)
       {
           try
           {
               pdfViewer.Print();
           }
           catch (Exception ex)
           {
               var aux = ex;
           }

       }
   }

As you can see I use byte[] for source and then a converter for stream. It displays ok. Should I store it as stream instead?

Any help appretiated.
Thanks

I actually found out.
I was using Silverlight telerik dll's Silverlight5_2012_1_0227; I updated to Silverlight5_2012_1_0326 and it solved.

Thanks anyway
PS. Someone please mark this as solution
