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

JavaScript
  • function registerKeyHandlers () {
  • const dropDownBox = $("#dropDownBoxContainer").dxDropDownBox("instance");
  • dropDownBox.registerKeyHandler("backspace", function(e) {
  • // The argument "e" contains information on the event
  • });
  • dropDownBox.registerKeyHandler("space", function(e) {
  • // ...
  • });
  • }
