    Hello Eyal,

    I'm afraid that the provided information is not sufficient in order to track the cause for the described error. Please provide a small runnable test page in which the issue can be observed locally.

    Also you should verify that the Kendo scripts are correctly included and there are no duplicate scripts (either Kendo UI or jQuery) loaded on the page.
