The R1 2020 Service Pack of Telerik Reporting and Telerik Report Server is now live! We bring important enhancements and bug fixes.

Below are some of the improvements that are part of our brand-new service pack release:

Skip Blank Pages in the Rendered Report

The rendering engine is now forced to skip all pages that do not contain significant content. The latter are considered blank and this includes all pages that only contain items of the following type: Report, Group, any Section, empty SubReport item, Cross-section item, i.e., they do not contain items like TextBox, PicturePox, Table, etc. 

You can still control this rendering behavior, so that pages that do not contain significant content get rendered by setting the SkipBlankPages property of the report to False

Skip Blank Pages in the Rendered Report

All Report Viewers and paged export formats (without RTF-Table mode) conform to this behavior. The viewers show a dedicated message in the report area when it appears that the report has no pages to display.

Improved Web Report Designer

With each release, we invest a lot of time and effort on our Web-based report designer to make it a fully functional report authoring tool. Now deleting an item from a report with many live items is much faster than before and over 10 bugs were fixed for the Service Pack.


The ASP.NET Core service implementation no longer requires setting the property AllowSynchronousIO to true. Basically, in .NET Core 3+ by default synchronous operations are disallowed. These operations are used to download resources such as images used in the reports. Previously, they needed to be manually allowed by setting the AllowSynchronousIO to True in the container services(Startup.cs) which now is not necessary.

Item Templates

The report viewers' item templates for Visual Studio are now listed in various technologies. This means when you add a new viewer page or window, only the respective item templates according to UI technology and target .NET framework will be shown.

API Changes

Using asynchronous methods required changing our public API. Please make sure to check the release history about the changes you may need to apply to your applications.

CORS Configuration for Report Server

Now the Telerik Report Server provides a way to configure the application's CORS settings. It can be configured during the application startup by the CORS extensions provided by the Microsoft.Owin middleware. The CORS setting can have one of the following states: Enabled, Disabled, Not Set.
