React SelectBox - Keyboard Support

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

Key Action
Alt + ↓ Opens the drop-down list.
Alt + ↑ Closes the drop-down list.
Esc Closes the drop-down list and removes focus from the UI component.
↑ / ↓ If the drop-down list is opened, moves focus to the previous/next item; otherwise, selects the previous/next item.
Page Up / Page Down Moves focus to the first/last item.
Enter or Space Selects the item.

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

  • <DxSelectBox :ref="mySelectBoxRef" />

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