Description
How can I create a Kendo UI for jQuery Scheduler on the client and then sync the changes with the batch mode turned on?
Solution
The following example demonstrates how to achieve the desired scenario.
<div id="example" class="k-content">
<button id="sync">Sync</button>
<div id="scheduler"></div>
<div id="overlay" class="k-overlay" style="display:none"></div>
</div>
<script>
