DevExtreme Vue - Keyboard Support

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

Key Action
↑ or Page Up Moves focus to the previous radio button.
↓ or Page Down Moves focus to the next radio button.
Home / End Moves focus to the first/last radio button.
Enter or Space Selects the focused radio button.

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

  • <template>
  • <DxRadioGroup :ref="myRadioGroupRef" />

  • }
  • },
  • computed: {
  • radioGroup: function() {
  • return this.$refs[myRadioGroupRef].instance;
  • }
  • },
  • mounted: function() {
  • this.radioGroup.registerKeyHandler('backspace', function(e) {
  • // The argument "e" contains information on the event
  • });
  • this.radioGroup.registerKeyHandler('space', function(e) {
