I created a new ASP.NET Web Application targeting the 3.5 framework and added a reference to the Telerik controls. I receive a Javascript error "Object doesn't support this property or method" when I click on the box. It is occuring on the eventArgs.set_cancel(true); line and it causes the sample to not behave as expected.
What am I missing? I was browsing the documentation and didn't see anything related to this.
Below is the entire aspx file.

eventArgs.set_cancel(true);

Hi Brian,
From what I understand the set_cancel() method is not supported by OnClientItemsRequested event. Try your code in the OnClientItemsRequesting event ans see if it is working.
ASPX:
JS:
Thanks
