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

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