- const dateRangeBox = $("#dateRangeBoxContainer").dxDateRangeBox("instance");
- dateRangeBox.registerKeyHandler("backspace", function(e) {

- });

To improve accessibility, use the startDateInputAttr and endDateInputAttr properties to specify aria-label for the component. You do not need to specify aria-label
if you use startDateLabel or endDateLabel correspondingly.
