Microsoft .NET 5-compatible Microsoft Visual Studio Report Designer (CTP)

  • You can now design reports for .NET Core and .NET-based apps within Visual Studio. This new Report Designer is fully functional: you can bind reports to data, use report wizards and data sources, drag and drop report controls/fields onto the report design surface, and execute report-related operations.
  • All reports migrated to .NET 5 should function as expected within apps that have already been converted to .NET 5 SDK.
  • Also enhanced theObjectDataSource and Entity Framework data sources. You are now able to discover custom types defined in your assemblies and projects built against .NET and .NET Core.

All Platforms

  • PDF Export - Tagged PDF - The PDF export engine can now produce tagged PDF documents for those who use screen readers and other assistive technologies.You can export documents that conform to the following standards:
    • PDF/UA.
    • PDF/A-1a, PDF/A-2a, PDF/A-3a.
  • DevExpress report controls ship with a new AccessibleDescription property. This property maps alternate text for PDF elements and allows you to describe the control's visual content and make it accessible to screen readers.
  • New Barcodes - Identcode and Leitcode - v21.1 extends the barcode library with two new barcode types:
    • Deutsche Post Identcode.
    • Deutsche Post Leitcode.
  • Use the new DeutschePostIdentcodeGenerator and DeutschePostLeitcodeGenerator classes to generate Deutsche Post Identcode and Deutsche Post Leitcode barcodes at runtime.
  • Federation Data Source - Fluent API - The Federation Data Source allows you to combine data from multiple sources. This release implements a Fluent API that allows you to create transformation-based operations to these sources. You can flatten and unfold columns, or apply the two operations together.
  • Microsoft Excel Data Source - Binding by a Sheet Index - Added a new WorksheetIndex property that simplifies binding to Excel files. The property allows you to bind a report to a specific Excel file sheet by index. You can use this property instead of the 'WorksheetName' property when you don't know the name of the sheet to which you want to bind a report and/or to avoid mistakes with sheet names.

  • Web Report Designer - Multi-Tenant Support - You can now restrict access to data by user. User access may be restricted to specific rows and columns within a table. Use our new service (ISelectQueryFilterService) in your multi-tenant environment to filter every SELECT query before it is executed (to retrieve data for the Document Viewer, Report Designer's Preview, or Query Builder).
