DevExtreme React - 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.

jQuery
JavaScript
function registerKeyHandlers () {
    let rangeSlider =  $("#rangeSliderContainer").dxRangeSlider("instance");
    rangeSlider.registerKeyHandler("backspace", function (e) {
        // The argument "e" contains information on the event
    });
    rangeSlider.registerKeyHandler("space", function (e) {
        // ...
    });
}
Angular
TypeScript
import { ..., ViewChild, AfterViewInit } from '@angular/core';
import { DxRangeSliderModule, DxRangeSliderComponent } from 'devextreme-angular';
// ...
export class AppComponent implements AfterViewInit {
    @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
    ],
    // ...
})
