According to the documentation for Scheduler.select() this method should "Gets or sets the events (or slots) which are selected." But if I pass in an array of multiple uid elements it only selects the last item in the array.

Code

jsbin example: https://jsbin.com/nirisakavo/1/edit?html,js,output

Really just added a function to select all:

function SelectAll() {
  var scheduler = $("#scheduler").data("kendoScheduler");
  var allEvents = scheduler.data().map(function(val, i) { return val.uid; });
  scheduler.select(allEvents);
}

Repro

Click the 'Select All' button.

Expected: Selects all events.

Actual: Selects only last event.
