Telerik Report Server

Release History

Telerik Report Server R3 2017 (version

September 12, 2017

SQL Data Schema Retrieved on Server

  • Reports data should be accessible from the report server. To verify that and as a security improvement, we have cut the need for a direct connection from the Stand-alone report designer to the SQL DB server. The data schema and sample preview data are retrieved from the Report Server WebAPI.

Web Report Preview Accessibility

  • Introduced for all HTML5-based report viewers. We have added accessibility features up to the standards in both the viewers' widgets (parameters area, toolbar, document map) and report content - detailed item information, keyboard navigation and interactive actions triggering.

New Financial Charts

  • Added presentation of financial data with candlestick and bar markers.

What's Improved

  • Significant performance improvements for Crosstab generation, Excel rendering and PDF rendering extensions, as well as memory usage optimization for the PDF rendering extension.

What's Changed

  • Based on the improved data handling, new server reports can only use Report Server shared Data Connection. This ensures that only connections created from the Report Server Data Administrators are used in the new reports. Same rule applies when one edits the connection of an existing report.
