DevExtreme Angular - Keyboard Support

An end user can use the following keys to interact with the widget.

Key Action
← / → Decreases/increases the value of the focused handle by a step.
Page Up / Page Down Decreases/increases the value of the focused handle by a keyStep.
Home / End Sets the focused handle to the minimum/maximum value or to the value of the other handle.
Tab / Shift + Tab Switches between the handles.

You can implement a custom handler for a key using the registerKeyHandler(key, handler) method.

TypeScript
  • import { ..., ViewChild, AfterViewInit } from '@angular/core';
  • import { DxRangeSliderModule, DxRangeSliderComponent } from 'devextreme-angular';
  • // ...
  • export class AppComponent implements AfterViewInit {
  • @ViewChild(DxRangeSliderComponent, { static: false }) rangeSlider: DxRangeSliderComponent;
  • // Prior to Angular 8
  • // @ViewChild(DxRangeSliderComponent) rangeSlider: DxRangeSliderComponent;
  •  
  • ngAfterViewInit () {
  • this.rangeSlider.instance.registerKeyHandler('backspace', function(e) {
  • // The argument "e" contains information on the event
  • });
  • this.rangeSlider.instance.registerKeyHandler('space', function(e) {
  • // ...
  • });
  • }
  • }
  • @NgModule({
  • imports: [
  • // ...
  • DxRangeSliderModule
  • ],
  • // ...
  • })
