We wanted to notify you that the Silverlight Report Viewer component will be obsoleted starting the R1 2023 SP1 release. After this release, we will no longer be providing updates, bug fixes, or support for this component.

The Silverlight Report Viewer has been an important component of Telerik Reporting for some time, and we understand that some of our users may still rely on it for their reporting needs. However, based on the fact that the Silverlight framework is obsoleted we have decided to retire this component in order to focus our efforts on providing the most up-to-date and effective reporting tools to our users.

We strongly recommend that you migrate to our HTML5 Report Viewer, as it offers enhanced functionality and performance compared to the Silverlight Report Viewer. Our team is ready to assist you with any questions or concerns you may have during the migration process.

Thank you for choosing Telerik Reporting for your reporting needs. We are committed to providing you with the best possible experience, and we are confident that our HTML5 Report Viewer will meet your needs and exceed your expectations.

If you have any questions or concerns, please don't hesitate to contact our support team.

All HTML5-based Report Viewer controls are built on top of the jQuery Kendo UI components. As announced earlier in January 2022, with R1 2023 we will stop the support for LESS themes in Telerik and Kendo UI products. Any customer using the LESS themes is advised to migrate to an equivalent SASS-based theme instead. To learn more about why this change is happening and how it might affect you please review the “Future Plans for the Telerik and Kendo UI LESS Themes” blog post.

Introduce built-in support of report embedding for preview with all of its settings enabling the end-user to switch to report design. This will allow the end-user to change and save a report definition when needed. 

We will introduce support for Kendo UI SASS themes in the HTML5 Report Viewer as well. We will continue developing our web-based report viewers and report designers with SASS theming in mind.

We will create extensibility points in the viewers to callback on the progress of the report generation.

We will continue improving the efficiency of our mature report generation engine.

Such components will allow easy embedding of the Web Report Designer into Angular and React applications.

Column reordering is the second common operation next to the column resizing in a Table item. We will implement that operation with drag-drop action for the Web Report Designer.

We will introduce contextual help hints and links to documentation so that a user can easily learn to use the Web Report Designer

We will implement the Visual Studio Report Designer for .NET Core, .NET 5, and .NET 6 projects to enable integrated design-time experience for these MS technologies.
