Hello Stephen,

Using data-bind="source" instead of data-source will make the DatePicker widget display as expected in the Toolbar. Here is the modified example for reference.

Let me know if you have any further questions.

Hello Stephen,

Currently using data-bind=source is the proper way to bind the dataSource like in our official demo. We will need to do some testing to see if there is a limitation when using data-source. If that is the case, we will consider mentioning it in our documentation.

We wanted to use the Scheduler widget using jQuery and attributes only without implementing Telerik data bind. Please let me know if you find out this is a bug.

Thank you
