Hi Peter,
Thank you for contacting Syncfusion support.
We have checked your reported issue and we would like to let you know that currently we don’t have an option for unselect event. However, we have considered this as an improvement, in this we will provide the change event for listbox control. And this fix will be available in our upcoming(EJ2 weekly release). We will update you once the fix will be available, until then we appreciate your patience.
