    I have a combo box set up to cascade to another combo box. This works.  I have mapped both a change event and a select event in the "parent" - - both of which also work. I am planning to observer the state of the "parent"  knockout via the knockout-kendo plugin.  I expect this to work.

    BUT - I need to be able to trigger the cascade programmatically, as well.  That is, I need to programmatically change the selected index of the "parent".  To test this in advance of mapping it in knockout,  I have a test button that successfully changes the selected item in the "parent".  So, this works.

    Here is problem: neither the change event nor a select event are triggered in response to the following (which is in the test button click handler):
    var cbx = $("select").data("kendoComboBox");
    That is, the combo box changes state but kendo is not triggering either of  the events.

    I have tried this in various fiddles (modifying a similar situation) and it does not work there either.

    This is quite important to us, so please let me know if this is not supported.

    Hello Jayesh

    Thanks for the reply and this indeed works, though I am exactly sure why. 

    As a input to telerik, this is not in any documentation I can find - nor is the trigger function immediately obvious in the any of the fn objects under the kendo namespace.  I guess the answer is that since this is clearly a (modified) jQ event object, it should inherit the jQ trigger function - which would map tot the cached jQ events. Is that correct in your view?

    Again, thanks for assist.

    Hello guys,

    Actually the trigger method is documented - it is a common method for the kendo.ui.Widget class and is inherited from kendo.Observable.
