Hello Bill,

A possible approach would be to bind to the edit event of the Scheduler and bind an event handler to the desired input field. In this Dojo example, I can get a reference to the DropDownList for the repeat rule, and bind a handler to the change event:

edit: function(e) {
  var ddl = $("input[title='Recurrence editor']").data("kendoDropDownList");
  ddl.bind("change", ddlChange);
}

I hope that will help you achieve the desired result. Let me know if you have any questions.

Regards,
Martin
