Release History

Progress® Telerik® Reporting R2 2022 (

May 11, 2022

.NET 7 Preview 3 support for desktop viewers and REST service

  • Added support and dedicated example solution for .NET 7 Preview 3 in the WinForms and WPF report viewers as well as the REST service which can be used as a remote report generation engine.

Web Report Designer is now compatible with the theming and widgets of the latest generation of Kendo UI (Kendo UI R1 2022 SP1+).

  • Web Report Designer now uses the latest generation of Kendo UI themes and widgets - Kendo UI R1 2022 SP1 (version 2022.1.301)

Web Report Designer now provides a comprehensive search function

  • Web Report Designer introduces a great UX improvement - the ability to search throughout all the designer areas: components, existing report items, or available properties. Now you can add a new component, navigate to the required report item or change a property value with just a few keystrokes.

What's Improved

  • Reordering reports in report books from the design surface has better visualization of the place of the dropped item
  • The Reports node in Assets Manager now supports folder hierarchy
  • IDefinitionStorage methods are now asynchronous
  • Editors that invoke Assets Manager have better design and improved UX
  • Table columns in Assets Manager grid view now support resizing
  • XAML rendering extension now allows disabling the validation for invalid characters
  • Tags are added for filtering of .NET Framework REST Service and Library project templates in Visual Studio

What's Changed

  • Telerik.WebReportDesigner.Services.IDefinitionStorage interface is extended with new members to support more scenarios for working asynchronously with report definitions. All custom implementations of this interface need to include the new members.
  • Telerik.WebReportDesigner.Services.IResourceStorage interface now extends a new interface: Telerik.WebReportDesigner.Services.IAssetsStorage. All explicit implementations of IResourceStorage interface must reference the new interface.

Standalone Report Designer

  • A NullReferenceException might be thrown when trying to add a new column in an existing Table or Crosstab item
  • Crosstab layout gets broken when inserting a child group and there is a spanned cell across the reference group item and the new group's item
  • Crosstab layout gets broken when inserting a column/row after a column/row containing merged cells and not crossing the Body
  • Crosstab layout gets broken when inserting a column/row before or after a column/row so that the new column/row crosses a merged cell
  • Selecting a column/row in the table designer does not behave correctly when there are merged cells in it
  • When a column/row containing a merged cell and crossing the Body is selected and a new column or a row is inserted before/after it, it gets positioned before/after the merged cell

Web Designer

  • Chart wizard type is not shown again if the report component selection is not changed
  • Clicking the "Browse" button and canceling the operation removes all previously added files when uploading in Asset Manager
  • Control key is "sticky" and is not released sometimes when item in Explorer tree is selected
  • Create button is disabled after you add data source fields using a Graph or Table wizard if there is another Graph or Table wizard opened
  • Date format specified on step 5 of CsvDataSource wizard is not being respected when the data is previewed on the last wizard page
  • Design surface is not shown after opening the Assets Manager when ResourceStorage is not defined
  • Design surface leaves unnecessary space around the report surface
  • InlinePropertyEditor Source is not expandable in CSV and JSON data source properties
  • Longer filenames show too few characters in Asset Manager list view
  • PictureBox Value Type, CheckBox Image Type, CSV Data Source Type, and JSON Data Source Type editors are not aligned with other editors
  • Report book icons in design mode are smaller after you return from preview mode
  • The Asset Manager Upload dialog closes when not all files are successfully uploaded
  • Web Report Designer does not perform validation on report parameter names


  • Our example solutions contain projects targeting .NET Core 2.1. which is currently out-of-support


  • A NullReferenceException is thrown when adding a parent column group in a Crosstab item

Data Binding

  • SQL Query using the "i" character fails when using Turkish culture settings

Excel Rendering

  • A generic error occurred in GDI+ when trying to export to XLSX format in Azure environment using a report that contains SVG


  • Desktop viewers print blank pages when they use REST Service hosted in .NET Core/5/6 application and the PaperKind is set to Custom
