MVVM

• Compile-Time ViewModel Generation
  • This feature uses C# Source Generators introduced in .NET 5 to generate boilerplate code for your ViewModels at compile time. Command declarations, property change notifications, IDataErrorInfo implementation and service support will be automatically added to a partial class linked to your ViewModel.
  • Compile-time code generation shares benefits associated with both runtime-generated POCO ViewModels and standard ViewModelBase descendants:
    • ViewModels are free of repetitive boilerplate code.
    • Generated code is stored in partial classes. You can view and debug the code easily.
    • ViewModel classes are the same at design time and runtime.
    • Best possible runtime performance since classes are generated in advance.
• EventToCommand - Event Args Back Conversion
  • When passing event args to a command, you can define back conversion logic and return values from a command to an event. This should simplify situations when an event expects a return value and UI-specific event args cannot be passed to a ViewModel. Examples of such events are validation, custom sorting and custom display text, etc.

New TreeView

    • CustomRowFilter.
    • CustomSummary, CustomSummaryExists.
    • AddingNewRow.
    • RowCanceled, NodeCanceled.
    • RowUpdated, NodeUpdated.
    • RowDoubleClick, NodeDoubleClick.
    • ValidateRow, ValidateNode.
  • These commands pass a typed parameter and expose UI-independent event args to the ViewModel. This change allows you to return values back to an event by simply modifying the command parameter at the ViewModel level.
• MVVM Support in Virtual Sources
  • You can implement data operations for Virtual Sources at the ViewModel level without introducing dependencies to the UI. Virtual Sources introduce new command properties in addition to events. Command parameters expose a platform-independent API that allows you to pass data from the ViewModel to the Data Grid.
• Bind to gRPC
  • Added the ability to use Virtual Sources to bind the WPF Data Grid to gRPC service.

Accordion

Grid adds custom row layouts and cell/row hot track in Table and Banded Table views.

Features

New Lightweight Installer

• New lightweight installer (about 110MB in size) that does not include demo and documentation files. Nevertheless, as you proceed through the setup process, you'll have the option to separately download and install demos/documentation if you decide you need them. The Download Manager offers the new installer as a separate option to the full installer.

Grid Control

• Custom Row Layouts in Table and Banded Table Views - This feature was first introduced in November 2020 as a community technology preview (CTP). This update marks its official release, and has the following enhancements:
  • Print/export support.
  • Smart cell navigation.
  • Automatic cell height adjustment.
  • Ability to customize caption suffixes.
  • Size modes for multi-line cell editors.
  • Ability to specify minimum allowed cell widths.
• Performance Enhancements - Significantly improved the data controller's performance with Master-Detail layouts. Master row expansion and data editing in detail rows are more than three times faster than in previous versions. The performance benefits increase with the number of master rows that the Grid control displays.
• Cell/Row Hot Track - Added the 'OptionsBehavior.HotTrack' option to both the Table and Banded Table Views. Use the View's 'Styles.HotTrack' property to customize appearance settings applied to hot-tracked cells/rows.
• Customizable Cell Border Visibility - Set the new 'CellBorders' property to False to hide cell borders in Layout Views, non-modal Edit Forms, and custom row layout fields.

Spreadsheet

• Performance Enhancements
  • Thanks to a new stream-based XML parser, large XLSX documents load up to 70 times faster, while consuming 60% less memory.
  • XML, HTML, TXT, and CSV export routines now use a shared memory buffer for strings to reduce memory fragmentation.
  • Clipboard operations with large cell ranges now consume about half the memory.
  • The cell pack algorithm now updates the default cell style instead of storing redundant cell information when a user changes the style of all cells at once. This change reduces the document size as well as memory consumption.
  • The parser no longer uses an exception-based mechanism to validate strings that should be converted to dates. This optimization speeds up load operations from TXT and CSV files, and also paste operations from the clipboard.
  • Best Fit calculations now use the same canvas to draw rows. With this change, cell draw operations will work up to three times faster depending on the number of populated rows and cells in a document.

Layout Control

• Performance Enhancements
  • Optimized scroll operations make the UI more responsive, due to the calculations for scroll position being up to five times faster.
  • With major improvements to drag initialization (up to 100 times faster), drag-and-drop operations during layout customization are much smoother.

  • The parser no longer uses an exception-based mechanism to validate strings that should be converted to dates. This optimization speeds up load operations from TXT and CSV files, and also paste operations from the clipboard.
  • Best Fit calculations now use the same canvas to draw rows. With this change, cell draw operations will work up to three times faster depending on the number of populated rows and cells in a document.

PDF Viewer

• Save Functionality and Document Content Modification - Introduced the document save functionality in November 2020 as a beta. v21.1 marks its official release and adds the following document content modification methods:
  • Merge documents.
  • Insert, delete, or rearrange pages.
  • Manage file attachments.
• Page Rotation - The PDF Viewer has a new "Rotate Pages" dialog available in page thumbnails. You can save page orientation changes with the other content changes.
• Visual Signatures - The PDF Viewer allows you to add an image to a digital signature and save it with the other content changes.

Layout Control

• Performance Enhancements
  • Optimized scroll operations make the UI more responsive, due to the calculations for scroll position being up to five times faster.
  • With major improvements to drag initialization (up to 100 times faster), drag-and-drop operations during layout customization are much smoother.
  • With this release, locked layout groups are drawn up to five times quicker.

Miscellaneous

• The Fluent Design Form now supports two background effects - blur and transparency - in addition to the standard acrylic effect. The form's new 'BackgroundBlur' property allows you to apply the desired effect.
• v21.1 introduces a new render mode (GDI+) for graphics-intensive controls that display multiple semitransparent geometric primitives. This mode accelerates rendering for such controls and applies antialiasing to displayed shapes.
• The cloud storage component now has synchronous methods for interaction with external storage, in addition to the asynchronous API made available earlier.
• Modern-style hints in the Scheduler control can optionally display resources associated with events.
