print dialog not showing

[richard]

On my development pc I have used some ideas from this forum to implement direct printing from Silverlight( well sorta direct as it skips showing the reportviewer). The user is supposed to be presented the Print dialog box which works great on my dev PC. When moving the xap and dlls to the testing server the user is never shown the print dialog box therefore nothing happens.

Any ideas why it wont show on the server?

Thanks much,
Richard

Hi Richard,

We will need additional information. Please share the printing code you have used. Generally our recommendation is to review the following forum thread. Additionally you may find useful the Silverlight Printing MSDN article. 

All the best,

1) the reportviewer is defined in the xaml
2) the URI is all defined in the XAML
3) this works on local dev PC
4) I upload to the server and nothing happens after pressing the Print button - no error is returned or raised when it should show the system Print Dialog box

here is the code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Telerik.ReportViewer.Silverlight;
using Telerik.Reporting.Service.SilverlightClient;

Hi Richard,

The issue you are having is most probably due the fact that you have set the ReportViewer.UseNativePrinting property to false and you are using Firefox 19 or later. For more information please check this help article about True Print - with this setting printing depends on the browser's PDF plug-in. If you have issues only in Firefox 19 or later, the reason is in the newly introduced native PDF plug-in in it. The fix is available in Telerik Reporting Q1 2013 internal builds.

If this is not your issue please elaborate and it will be best if you can provide us with runnable samples so that we are able to reproduce the issue locally and advise you more accordingly.

Kind regards,
Stef

i use Chrome and yes it is set to FALSE. Also tried IE 9.

Anyways I give up...went back to showing the ReportViewer.

Case can be closed.
