Hello,
I have the exact same issue reported over two years ago here - http://www.telerik.com/community/forums/aspnet-mvc/combobox/dropdownlist-does-not-change-its-input-value.aspx
Using the plugin they are also using, I have found changes to dropdowns were not being tracked. I believe the root of this issue is from this user's post:
"However, using .val() does not fire a change event. In html's select dropdown and not telerik's dropdown, selecting a different value fires a change event. In your case, you change the value via .val() but forget to trigger a change event which I think you should do via $('#').val().change();"
Telerik's reply back in sept 2011 was that this would be forwarded to the developers. I am not interested in wiring up a valueChanged event handler to every dropdownlist, and was hoping to get an update on this issue. Shouldn't telerik's dropdown follow the same event pattern as a standard html dropdown in terms of firing events? If there's a reason it shouldn't, is there any global solution for this issue?

Hi Glen,
The forum post that you are referring to reference the combobox control of the ASP.NET MVC suit. If that is your case I would kindly ask you to post your question in the respective forums. Here is a list of the Telerik products that you can review. Let me know also if I am mistaken and you are referring to the RadcomboBox control of the ASP.NET AJAX suit.

Sorry for the confusion. This is related specifically to the telerik ASP.NET Ajax RadDropDownList.
The issue is summarized as below:
using .val() does not fire a change event. In html's select dropdown and not telerik's dropdown, selecting a different value fires a change event. In your case, you change the value via .val() but forget to trigger a change event which I think you should do via $('#').val().change();

Hello Glenn,
Thank you for contacting Telerik Support.
The RadDropDownList controls rendering differs from the standard html select. Therefore, we recommend the usage of the Client API of the control, where you could observe the for changing the selection of the control you could use the set_text() method (or get a reference to a specific item and use set_selected()) and for capturing a change of the value - you could use the OnClientSelectedIndexChanged.
Hope this information helps. I will be glad to assist you any further.
