Dear Telerik team ,

I have implemented the below code for external print button functionality in silverlight with a report having more than 20 pages. I have tested this using XPS printer I have found few of the pages are not printed correctly. Out of 20 pages I have found 2 pages are printing partially every time.(Page 7 and page 14). if the chart size increase it is becoming more worse.
Is is possible to show a progress bar before print dialog appears.
I have attached the screen shot for your reference. Please help on this issue.

Hello Kiran,

We were not able to reproduce such problem on our end. Find attached the report we used and the exported PDF file. If you're still having problems, we would appreciate if you open a support ticket and attach a sample project (the whole thing) so we can run it as is. You can also upload it to a free file hosting and provide a link here.

Kind regards,
Steve
