Keyboard Navigation Enhancements

This release includes new keyboard behavior options. These options allow you to address a variety of high-speed data entry usage scenarios.

• Start Editing via KeyPress

  Users can now instantly edit data - no need to switch to edit mode.

  

• Configurable Enter Key Action

  You can specify whether an Enter key press switches to edit mode or moves focus to the next cell.

  

• Configurable Enter Key Direction

  You can configure an Enter key press to move cell focus to the next column or row (horizontally or vertically).

  

Accessibility Enhancements

You can now navigate to and interact with DataGrid and TreeList UI elements (such as headers, pager controls, and the command column) via the keyboard.

New DoubleClick Events

• onCellDblClick - fires when a user double clicks a cell.
• onRowDblClick - fires when a user double clicks a row.

Data Editing - New API

• editing.selectTextOnEditStart - Determines whether cell text is auto-selected when a user starts to edit a cell's value.
• editing.startEditAction - Specifies whether a single or double cell click initiates data edit operations.

TreeList - A New Filter Mode

We've extended the filtering capabilities of the TreeList with a new data filter mode. When used, filter results include the children of filtered nodes.

DataGrid - New Export To Excel API (CTP)

This release (available as a CTP) includes a new, more flexible API based on the ExcelJS library. Features include:

• Ability to add a custom header/footer
• Export multiple grids into a single worksheet
• Export multiple grids into a single document using separate worksheets
• Rename the exported file
• Generate worksheets with custom content
• Display a loading indicator for large datasets

This feature can be used in conjunction with our existing export to Excel API. As such, it won't break your existing apps and can be tested independently.

New Dropdown Button Widget

v19.1 introduces a new button widget with a built-in dropdown menu. This widget can be used as a stateless set of clickable menu items or as a stateful analog of a SelectBox control (which looks like a button).

New Floating Button Widget

Our new Floating Button Widget is a single button positioned at the bottom corner of the screen. It contains one or more primary screen actions. The floating button widget follows Google's Material Design guidelines.

HTML/Markdown Editor - Resize Media Blocks

You can now resize images and video blocks via mouse operations:

HTML/Markdown Editor - Mentions Support

Mentions allow you to select users or user groups by typing @ when composing rich text content. You can also implement any custom embedded lookups such as issue references using # symbol as a prefix.

Text Editors - Custom Buttons

With this release, you can add additional buttons to data editors and reorder built-in actions.

Remote Data Paging

Our PivotGrid’s data layer can now request the data it needs for an individual page. Remote data paging improves performance against large volumes of aggregated data.

PivotGrid - Cascade Filtering

Our PivotGrid can now apply parent field filters. For instance, if you filter the PivotGrid by the 'Country' field, the 'City' field's filter items will also be filtered against the same Country.

Adaptivity and UX Enhancements

We have improved Scheduler usability on mobile devices. In v19.1, the Scheduler control renders a popup appointment list instead of a tooltip. The appointment list is displayed in full screen mode.

The appointment edit form is also rendered in full-screen mode on mobile devices.

In addition, larger appointment markers are now used on mobile devices.

Chart Annotations

You can now annotate charts with custom labels.

Legend Enhancements

• Customize Legend Items

  We added a 'legend.customizeItems' callback so you can change the order, text, and visibility of legend items.

  Documentation Demo

• Legend Title

  A legend title can now be specified and configured using the 'legend.title' option. You can customize the title's appearance and its position, and add a subtitle as well. This new option offers the same capabilities as the widget's root title option.

  

  Documentation Demo

• Add a Legend to the Bar Gauge

Resolve Label Overlaps

The resolveLabelOverlapping option allows you to specify widget behavior when labels overlap one another.

• Resolve Label Overlaps within a Funnel Chart

  In the Funnel, this option accepts 'shift' (default), 'hide' and 'none.' If no room exists to display all labels after a shift, the algorithm hides labels as needed.

  resolveLabelOverlapping accepts 'hide' (default) and 'none'.
