Silverlight ReportViewer Dialog 'Preparing to Print' Dialog missing

[Roger]

I am using Telerik Reporting Q3 2010 with Silverlight ReportViewer on SL4.
The Report shows more than one page and displays ok so far.

But if i hit the print button, no print dialog comes up and the "Preparing to print" dialog does not show up.
If i display all of the report-pages by using the navigation-arrows and after this hitting the print button, the report dialog shows up. 

In the end, the whole thing has to run under ria and https. but for the test, i just use some fake-data, that is generated in the report.
I also managed to create another solution with https calls and the same scenario. there it works, but i dont see the differences.

i ddi a printscreen of the included assemblys.
do i miss some references or initializations?

The Clientside-Call:

Telerik.ReportViewer.Silverlight.ReportViewer rep = new Telerik.ReportViewer.Silverlight.ReportViewer();

rep.Report = "InoTrans.Web.Report1, InoTrans.Web";

Uri uribase = Application.Current.Host.Source;

rep.ReportServiceUri = new Uri(uribase, "../Services/ReportService.svc");

(((App)Application.Current).RootPage as MainPage).frmContent.Content = rep;

Telerik.ReportViewer.Silverlight.ReportViewer rep = new Telerik.ReportViewer.Silverlight.ReportViewer();

rep.Report = "InoTrans.Web.Report1, InoTrans.Web";

Uri uribase = Application.Current.Host.Source;

rep.ReportServiceUri = new Uri(uribase, "../Services/ReportService.svc");

(((App)Application.Current).RootPage as MainPage).frmContent.Content = rep;

Telerik.ReportViewer.Silverlight.ReportViewer rep = new Telerik.ReportViewer.Silverlight.ReportViewer();
rep.Report = "InoTrans.Web.Report1, InoTrans.Web";

Uri uribase = Application.Current.Host.Source;
rep.ReportServiceUri = new Uri(uribase, "../Services/ReportService.svc");
(((App)Application.Current).RootPage as MainPage).frmContent.Content = rep;

The Report:

namespace InoTrans.Web
{
    using System;
    using System.ComponentModel;
    using System.Drawing;
    using System.Windows.Forms;
    using Telerik.Reporting;
    using Telerik.Reporting.Drawing;
    using InoTrans.Web.Services;
    using System.Collections.Generic;

    /// <summary>
    /// Summary description for Report1.
    /// </summary>
    public partial class Report1 : Telerik.Reporting.Report
    {
        public Report1()
        {
            //
            // Required for telerik Reporting designer support
            //
            InitializeComponent();

            //
            // TODO: Add any constructor code after InitializeComponent call
            //
            List<EntLtd> list = new List<EntLtd>();
            for (int i = 0; i < 100; i++)
            {
                EntLtd ent = new EntLtd();
                ent.sLtdAdrOrt = "Testort";
                list.Add(ent);
            }
            this.DataSource = list;
        }
    }
}

                    MacProgressBarStatic.CloseProgressBar(progress, AwoKonstanten.GuiDelay_long);

                    Telerik.ReportViewer.Silverlight.ReportViewer rep = new Telerik.ReportViewer.Silverlight.ReportViewer();

                    //rep.Report = "InoTrans.Web.Selbstdeklaration, InoTrans.Web";

                    rep.Report = "InoTrans.Web.Report1, InoTrans.Web";

                    //Angabe wo relativer pfad beginnen soll.

                    Uri uribase = Application.Current.Host.Source;

                    rep.ReportServiceUri = new Uri(uribase, "../Services/ReportService.svc");

                    (((App)Application.Current).RootPage as MainPage).frmContent.Content = rep;

                    MacProgressBarStatic.CloseProgressBar(progress, AwoKonstanten.GuiDelay_long);

                    Telerik.ReportViewer.Silverlight.ReportViewer rep = new Telerik.ReportViewer.Silverlight.ReportViewer();

                    //rep.Report = "InoTrans.Web.Selbstdeklaration, InoTrans.Web";

                    rep.Report = "InoTrans.Web.Report1, InoTrans.Web";

                    //Angabe wo relativer pfad beginnen soll.

                    Uri uribase = Application.Current.Host.Source;

                    rep.ReportServiceUri = new Uri(uribase, "../Services/ReportService.svc");

                    (((App)Application.Current).RootPage as MainPage).frmContent.Content = rep;

                    MacProgressBarStatic.CloseProgressBar(progress, AwoKonstanten.GuiDelay_long);

                    Telerik.ReportViewer.Silverlight.ReportViewer rep = new Telerik.ReportViewer.Silverlight.ReportViewer();

                    //rep.Report = "InoTrans.Web.Selbstdeklaration, InoTrans.Web";

                    rep.Report = "InoTrans.Web.Report1, InoTrans.Web";

                    //Angabe wo relativer pfad beginnen soll.

                    Uri uribase = Application.Current.Host.Source;

                    rep.ReportServiceUri = new Uri(uribase, "../Services/ReportService.svc");

                    (((App)Application.Current).RootPage as MainPage).frmContent.Content = rep;

The Value-Binding in InitializeComponent() looks like this:
 this.textBox1.Value = "=Fields.sLtdAdrOrt";

Thist effect seems to occur if a older Silverlight-Controls dll is used.
Installation of the appropriate Silverlight-Components Q3 2010 to Q3 2010 Reporting solved the Problem.
