New version of FastReport .NET 2021.4 is released

What's new in version 2021.4 of FastReport .NET?

FastReport .NET 2021.4

Important! Editions changes

The WinForms and Win+WebForms editions will no longer be supported. Instead, we added a new Standard edition that includes Windows Forms components, ASP.NET components, and .NET Core / .NET 5 / Blazor support.

New features

Added new Visual Studio-styled icons. You may switch between icon packs in the "View/Options/User Interface" window (or, "File/Options/User Interface" if you use ribbon UI):

 The new icons are well suited for hiDPI screens.

Added ability to reset the FastReport configuration stored in the FastReport.Config file in the user's profile. It can be done in the "View/Options/User Interface" window, the "Reset config" button. Restart of the designer is required in order to apply changes.

Added ability for the Text object to display DB filed names in a simplified form when designing a report. You can activate this option in the "View/Options/Objects appearance" window. This option is off by default. When you turn it on the Text object with a single DB field will display the field name part only, with no datasource name:

It makes the report look cleaner especially when it contains a lot of small objects. You still can see a full text of object in the status bar.

Added ability to set up each cell in the Matrix object's corner area. To do this use the cell's context menu and its commands "Split cell", "Merge cells":

FastReport .NET 2021.4

Added ability to connect to ElasticSearch. Connection is available in data wizard and from code.

Added barcode Japanese Post 4 - State Code.

FastReport .NET 2021.4

Added the collapse all/expand all buttons and, a search field for the report tree and data tree in the designer. When clicking on + tree will expand. On - tree will collapse.

FastReport .NET 2021.4

These changes should simplify working with reports containing many objects and/or data sources.

The RicthText to report objects converter has been significantly improved and optimized.

The number of available exports in WebReport Core/Blazor Server has increased significantly.

Added FastReport Business Graphics integration objects (\Extras\Objects\FastReportBGObjects).

Universal plugins FastReport.Data

Packages with FastReport.Data plugins have been updated. Now they include plugins for different FastReport editions (.NET, Core, CoreWin, Open Source) and automatically connect the necessary library, depending on the product you use. The FastReport edition 2021.3.0 or higher is required for correct work.

The FastReport.Core.Data, FastReport.CoreWin.Data, and FastReport.OpenSource.Data plugins are declared obsolete and are no longer supported.

Improvements in publishing user applications using FastReport

For user applications on .NET Core 3.0+ and .NET 5+ using FastReport.Core, FastReport.CoreWin, FastReport.OpenSource has been added Single File Applications (SFA) support.

Also, added support for publishing application with trimmed unused libraries - MSBuild property - PublishTrimmed*.

Warning! In some cases, you may need to explicitly specify the list of builds that .NET should not trim. This may be useful if your report script uses these libraries, but your application's code does not make use of them.

This is done using the TrimmerRootAssembly property. In this case, for example, it's explicitly stated that the System.Security library doesn't need to be trimmed:

 <TrimmerRootAssembly Include="System.Security" />


In the logic of the localization change, small changes were made.

Added package FastReport.Localization. This package contains localization files for FastReport.NET, FastReport.Core, FastReport.CoreWin, FastReport.Mono, FastReport.OpenSource products and creates the Localization directory in the output directory of the user project when adding this package.

Added new API for changing the localization using the CultureInfo type - FastReport.Utils.Res.LoadLocale(CultureInfo culture).

When this method is called, FastReport searches for the appropriate localization for the selected culture. Loaded locales are cached. For this method to work correctly, you must install the FastReport.Localization package from step 1 in your project or set the path to the folder with the localization files in the FastReport.Utils.Res.LocaleFolder property.

Changes and improvements in the WebReport Core/Blazor toolbar

Toolbar settings were moved from WebReport class to WebReport.Toolbar property of ToolbarSettings class.

Added toolbar settings: Position, color of dropdown menu, font, transparency of icons, changing icon color, changing content position. These properties are available in the webReport.Toolbar.

During report loading, the toolbar is no longer displayed.

Added the ShowOnDialogPage property to the Toolbar object (true by default), which will allow to turn off the toolbar rendering if a dialog window is currently open.

Added more exports to the toolbar dropdown menu. These properties are available in webReport.Toolbar.Exports.ExportTypes. List of added exports: HTML, Hpgl, Dxf, Json, LaTeX, Ppml, PS, Xaml, Zpl, Excel97, Svg.

ToolbarSettings toolbar = new ToolbarSettings()
 Color = Color.LightBlue,
 DropDownMenuColor = Color.LightBlue,
 ShowOnDialogPage = false,
 DropDownMenuTextColor = Color.Black,
 IconColor = IconColors.Black,
 Position = Positions.Right,
 FontSettings = new Font("Arial", 14, FontStyle.Bold),
 Exports = new ExportMenuSettings()
 ExportTypes = Exports.Pdf | Exports.Excel97 | Exports.Rtf
 // or
 //Exports = ExportMenuSettings.All
 webReport.Toolbar = toolbar;
