New API - BrickSelector and DataSourceManager Classes
In our upcoming update (v20.2.5), we will introduce classes designed simplify use of report document bricks and report data sources at runtime:
- BrickSelector - - allows you to access visual “bricks” from a report document based on brick type, its tag, or text. You’ll be able to call class methods and work with bricks usign a single line of code instead of iterating through numerous document bricks.
- DataSourceManager -retrieves data sources from a report and/or report controls with their own data source (such as Chart and Cross Tab). Class methods include an
includeSubReportsflag. As such, you’ll be able to obtain info on all document data sources via a single method call.
Documentation Updates
We have revised and updated the following documentation topics (topics related to the creation of custom report controls):
- Windows Forms - Add a Custom Control to the End-User Report Designer Toolbox
- WPF - Add a Custom Control to the End-User Report Designer Toolbox
- ASP.NET Core - Create and Register a Custom Control in the Report Designer Toolbox
- Create a Custom Progress Bar Control
We have also updated the following documentation topics:

End-User Documentation Updates
We updated the End-User Documentation section for the DevExpress Report Designer and Document Viewer controls. This portion of our help file now includes v20.2 related features/descriptions. Remember, you can freely distribute the End-User Documentation section of our help file with your solution.
F1 - A Quick Way to Get API Help
Did you know you can place the cursor on a DevExpress class, method, or property in Visual Studio and hit F1 to jump to relevant help topics in your web browser? For instance, you can focus on the JsonDataSource's FillAsync method and press F1. Many help topics include code examples that you can paste and run in your application. This feature is part of the DevExpress product installation aand does not require additional configuration (like installing offline help).
