DevExtreme React - What’s New in v22.2
UI Template Gallery
We extended the capabilities of our DevExtreme component library with a set of responsive UI templates. These ready-to-use UI “blocks” will allow you to focus efforts on application logic and minimize energy spent on app/UI design.
Range Bar Chart - Minimum Bar Size
Use the new minBarSize property to specify minimum size for bars displayed in the Range Bar Charts.
Data Visualization Components - Adapt to Container Resize
Our Chart, Gauge, and Map controls now automatically adapt to changes in container.
Export Field Panel Headers to Excel
You can now include field panel headers in an exported worksheet. The following field header export-related options available:
Field Chooser - Encode HTML
The new encodeHtml property allows you to process HTML tags as plain text or apply them to header filter values.
CSS Styles Enchancements
The following components are now rendered more consistently under different use-case conditions (applies to both our Generic and Material themes):
For instance, buttons within our Toolbar's overflow menu now reflect specified types and styling modes.
Validation Message Position
Our new validationMessagePosition option specifies the position of a validation message relative to the editor's input region. Available settings include: 'bottom' (default), 'top', 'left', and 'right'.
Show/Hide API Enhancements
The cancel parameter for onShowing/onHiding events now supports the Promise type. This allows you to execute asynchronous actions before components are displayed/hidden. This enhancement is available in the following UI components:
The show/hide methods now return a Promise object, which is resolved once the operation is complete. This Promise is rejected if the operation was cancelled.
Slider & Range Slider - Value Change Mode
The Slider and Range Slider components now include a valueChangeMode option. This option specifies when a slider's value is changed. Available modes include:
- The value changes when the user releases the slider handle.
- The value changes immediately whenever the user moves the slider handle.
Toolbar Adaptability - Multiline Mode
Our Toolbar can now wrap across multiple lines when it is wider than its container. Use the multiline property to enable multiline mode.
Accordion - Title Templates for Individual Items
You can now define title templates for individual items. Use the titleTemplate property as requirements dictate.
CheckBox - Cycle Through Three State
We extended the functionality of our CheckBox component. Users can now toggle between all three states by clicking a box (cycling from unchecked to checked and then to an indeterminate state).
Use the enableThreeStateBehavior option to enable this mode.
Calendar - Week Numbers
The Calendar component can now display week numbers. Use the showWeekNumbers property to enable this option.
The Calendar automatically sets the first week of the year based on culture (locale). We added the weekNumberRule property to specify the rule used to determine the first week of the year. Available rules include auto, first day, first four days, and full week.
SelectBox and TagBox - Submit Custom Items on Loss of Focus
We enhanced the default behavior of our SelectBox and TagBox components. These components create custom items when the user presses the Enter key or when the component loses focus.
And yes, you can assign a DOM event to the customItemCreateEvent property to change the default behavior as needed.
Form – Custom Label Template
Popup and Popover - Overflow Menu in Toolbar
Toolbars within our Popup and Popover components can now display an overflow menu.
Use the following API to customize the menu and toolbar items:
DateBox - Customize Today Button Text
You can now rename the Today button (which appears in 'date' and 'datetime' modes). The new todayButtonText property specifies the text for the button.
