title: Kendo UI Cascading Combobox - Check if initialised
body: <p>I am using the Kendo UI Cascading combo boxes in an MVC 4 application. The source is too complex to post here, however it follows exactly the same structure as the MVC demo on the Kendo UI site (<a href="http://demos.kendoui.com/web/combobox/cascadingcombobox.html" rel="nofollow">http://demos.kendoui.com/web/combobox/cascadingcombobox.html</a>).</p>
  
  <p>Occasionally I am getting the exception below, I assume this is because the page isn't fully loaded and the user has tried to interact with the page, therefore causing the combo to attempt to submit an AJAX request to get it's data.</p>
  
  <pre><code>Microsoft JScript runtime error: Cannot call method 'value' of kendoDropDownList before it is initialized
  </code></pre>
  
  <p>Is there a correct way of checking whether Kendo controls are fully initialised ? If not how can I catch this exception ?</p>
  
  <p>Thanks, Jon.</p>
