Telerik Reporting

Release History

Telerik Reporting R3 2017 (version

September 12, 2017

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

  • In Telerik.Reporting.Cache.Interfaces.IStorage we added a new DeleteSet() method. It should be implemented for any custom storage implementation.
  • Remove the DocumentFormat.OpenXml.dll from Telerik Reporting NuGet package. From now on for Office OpenXML document formats you have to add DocumentFormat.OpenXml NuGet package. We recommend version 1.0.0 because no additional configuration is needed. For newer versions the appropriate binding redirects should be added to the project's app.config.
