New DateRangeBox Component

The DateRangeBox component for Angular, React, Vue, and jQuery allows you to select a date range. Features include:

• Masked Input
• Popup and Calendar Customization

• Value Mode
• Input Validation

Data Grid and Tree List

Column Chooser Customization

Our new selection property allows you to configure selection options within the Column Chooser window. Available options include:

• Recursive selection
• Select all
• Select a column by clicking its label.

You can specify a search configuration object to customize search within the Column Chooser.

Our new position property allows you to specify the display location of the Column Chooser.

Data Filtering - UI Customization

Header Filter Customization in DataGrid, PivotGrid, TreeList, Gantt

You can now customize search options and the appearance of the search box in column header filters. You can set up the search box as a TextBox component, specify comparison rules, and timeout/delay (in milliseconds).

Use the search configuration object to globally configure search settings, or use the columns[].headerFilter.search configuration object to make changes to individual columns. Use the fields[].headerFilter.search property to configure search settings in the Pivot Grid.

Data Visualization

Charts — Сolor Gradients and Patterns

You can now customize styles and apply gradients, patterns, and images to DevExpress Charts.

Use the registerGradient() method to declare linear and radial gradient styles, and the registerPattern() method to declare pattern and image styles. These methods return a unique id for declared styles. In the series/point color object, specify the base color for labels and connectors and apply the generated id to the fillId field.

You can also use the highlight option to highlight series on hover and selection.

Charts — Customize Label Position in Series

Our new shift(x,y) method allows you to display series labels at a specified offset from their default position.

Gauge — Display Custom SVG Content

Use our new centerTemplate property to display custom SVG content inside our Gauge component.

BarGauge — Support 'Shift' Mode to Address Overlapping Labels

If BarGauge displays multiple values ​​next to each other, corresponding labels may overlap. Use the resolveLabelOverlapping property to specify how the BarGauge component modifies the position or visibility of labels. Available options include:

• Shift
• Hide
• None

In shift mode, the BarGauge automatically shifts labels when necessary.

UI Components

Overlay Components — Native Scrolling

Our Popup, Popover, and Tooltip components now support native scrolling, which improves usability on mobile devices.

If content height is greater than the height of the overlay component, the component displays the browser’s native scrollbar. With this new enhancement, you do not need to wrap content into our ScrollView component.

TreeView — Display Custom Expand/Collapse Icons

TreeView nodes can now display custom expand/collapse icons.

Use the collapseIcon and expandIcon properties to specify node icons. You can load icons from URLs, specify icons in CSS class (if working with external libraries), or display DevExtreme icons.

List — Select Items on Click

Our new selectByClick setting specifies whether to select an item when the user clicks its caption.

ColorBox — Hexadecimal 8-digit RGBA Format Support

You can now specify colors in hexadecimal 8-digit RGBA format. Our ColorBox component accepts the following color formats:

• 4- and 8-digit (#F00F, #FF0000FF)
• 3- and 6-digit Hexadecimal (#F00, #FF0000)
• RGB (rgb(255, 0, 0))
• RGBA (rgba(255, 0, 0, 1))
• Color Names

Menu — Add the 'url' Option for Items

We added a new url option for Menu items. With this enhancement, you do not have to implement complicated onItemClick event handlers. Use the linkAttr property to specify link attributes.

Improved Calendar Design

UI/UX enhancements include:

• 'Prev' and 'Next' arrows are now fully customizable Button components.
• We visually enhanced selection in different calendar views.
• The week number column has now a completely new look and feel.

Improved adaptivity allows you to deliver elegant and responsive web applications for desktops, tablets, and phones alike.

Floating Action Button — Compact Mode Support

We added a compact mode to our Floating Action Button component.

UI Template Gallery

Scheduler View

The Scheduler View allows you to deliver scheduling/information management solutions with absolute ease. It integrates our fully customizable Scheduler and Calendar components.

Features include:

• Day / Work Week / Month / Agenda Views
• Create and Edit Events (Appointments)
• Show/Hide Calendars

User Profile View

We use DevExtreme Form component to create a user profile view that allows you to edit and save user information.

Light and Dark Theme Switcher

Our UI Template Gallery application ships with a new theme switcher. Use it to switch between light and dark themes.

Authentication Forms

We improved the functionality and design of our "Sign-In" and "Change Password" forms. We added a show password option and "Login with Google/Microsoft" buttons.

Data Layer

DataSource — Sort and Filter by Locale

The DataSource can now sort and filter data by locale with special characters (for example, symbols with diacritics). Specify locale and collator options in the langParams object to implement this functionality.

Accessibility

We extended the following accessibility-related capabilities:

• Focus disabled UI elements
  Switching focus between accessible and disabled (unavailable) UI elements in our components now complies with the WAI-ARIA standard. Screen readers can now report a disabled element when the user focuses on it. Any other interaction with disabled UI elements is not allowed.

• Keyboard navigation in TreeView
  We improved the tab navigation (Tab key) between item checkboxes and 'selectAll' checkbox.

• Keyboard navigation in Calendar
  Users can focus the Today button and press Enter to navigate to the today date. Enable the showTodayButton setting to display the Today button within the calendar.

• Global rework of aria-* attributes
  This enhancement allowed us to better support screen readers in all UI components.

• Tabs and TabPanel — Design improvements in Material and Generic themes
  We added new visual states for our Tabs and Tab Panel components. And yes, we also improved existing states: hover, active, disabled, focused, and selected.

• Charts — Pattern and Image fill
  With this new customization option, you can edit styles, apply images and SVG patterns to DevExpress Charts, making them accessibile to visually impaired people.

We also improved the documentation of our DataGrid, TreeList, and dropdown editors. The documentation now includes help topics about accessibility support. Each help topic includes a table with the features and standards supported by the component (for example, Autocomplete Accessibility). We use Lighthouse, WAVE, and Axe accessibility tools to test our components and display results in the table. Review this information to learn about accessibility support and to see if your application is configured to meet accessibility standards.

And yes, we will continue to enhance accessibility support in future releases.

Security

Content Security Policy (CSP) Support

The DevExtreme UI library now supports Content Security Policy (CSP) integration and introduces advanced security features to help you detect and mitigate certain types of security risks, including Cross-Site Scripting (XSS) and data injection attacks. To make certain DevExtreme UI components support CSP, we run them through unit tests.

TypeScript Enhancements

• React component props now fully support types. TypeScript hints on errors in code, and IntelliSense to avoid them.

  

• You can now export all required types from framework specific packages. In previous versions, you had to import certain types from a separate devextreme package, while other types had to be imported from specific framework packages such as devextreme-angular.

  Angular React Vue

• Our documentation now includes over 500 topics related to types.
