Updates in 20.1.3

Features

.NET Core Design Time Support

• Apply application themes from App.config to all designer previews.
• Select non-visual elements (Data Grid columns, Toolbar and Ribbon items).
• Documentation and Application Theme Smart Tags.

New Splash Screen

• Ability to move a Splash Screen window.

Data Grid

• Virtual Sources - Data Editing - Infinite and Paged sources now support data editing via Edit Entire Row. End users can press the Update button after entering cell values to post changes to a data source asynchronously.
• Virtual Sources - Miscellaneous Enhancements
  • The WPF Data Grid bound to a virtual source can now process and display custom summaries.
  • The new ReloadRows method allows you to refresh individual rows. This method accepts a collection of row keys and passes them to the FetchRows event handler.
  • The WPF Data Grid now retains a selected row and scroll position after refresh if enough rows are loaded. Use the new Take property in the FetchRows event handler to obtain how many rows are within and above the viewport.

Data Grid and TreeList

• New Filter Panel - The new Filter Panel displays separate tokens with filters for each column.
• Filter Editor Enhancements - Extended operand types in the Filter Editor. Your end users can now select fields and date-time functions as needed.
• Automatic Column Best Fit - The Data Grid and TreeList can automatically (and dynamically) resize columns to fit cell values during scroll operations. To enable this option, set a column's Width property to Auto. As you can see in the animation below, the WPF Data Grid / TreeList controls automatically recalculate optimal cell width for the target column (and dynamically recalculate cell width as records are scrolled).
• Miscellaneous Enhancements
  • Use the TableView.ClipboardDataProvider and TreeListView.ClipboardDataProvider properties to obtain selected data during copy operations. You can get selected data in the following formats: TXT, RTF, Unicode, CSV, BIFF8, HTML.
  • New TableView.ClipboardRowCopying and TreeListView.ClipboardNodeCopying events allow you to customize copied data.
  • Set the RestoreStateOnSourceChange property to true. The Data Grid / TreeList control will restore component state (selection, focus, and grouping) when a new ItemsSource is assigned.
  • TableView.BestFitModeOnSourceChange / TreeListView.BestFitModeOnSourceChange

Accordion Control

• Restrict Item Selection - New API allows you to prevent accordion item selection.
  • The CanSelect property specifies whether an accordion item can be selected.
  • The CanSelectItem event allows you to prevent item selection based on a condition.
• Show Popup on Hover - Use the new ShowPopupOnHover property to display a popup on mouse hover. When the mouse pointer leaves a popup, the Accordion control hides the popup with a delay. The delay is specified by the PopupHideDelay property.

Charting
