Hi. I'm having the same issue.
I added the references to the default.html file:
<script src="http://cdn.syncfusion.com/js/assets/external/jsrender.min.js"></script>
<script src="http://cdn.syncfusion.com/14.1.0.41/js/web/ej.web.all.min.js"></script>
<script src="http://cdn.syncfusion.com/js/assets/external/jquery.easing.1.3.min.js"></script>
<script src="http://ajax.aspnetcdn.com/ajax/globalize/0.1.1/globalize.min.js"></script>
<script src="http://cdn.syncfusion.com/js/assets/external/jquery-1.10.2.min.js"></script>
<link rel='nofollow' href="http://cdn.syncfusion.com/13.1.0.21/js/web/flat-azure/ej.web.all.min.css" rel="stylesheet" />
The componentes like charts, datepicker and others, they are Ok. But the schedule componente, it shows an empty area in the screen.
Thying to solve the problem, I started to use the Nuget. But it didn't solve the problem.
Any help would be VERY useful.
Thank you very much.
