Hi,

We have customers reporting issues that the RadCombo box not working at all in IE 9 browser. When we debugged the issue we found that the ItemRequested event is not firing at all. The version that we currently use is Telerik.Web.UI, Version=2010.1.415.20, Culture=neutral, PublicKeyToken=121FAE78165BA3D4. 

I have seen in the forums that this is a known issue with older version and so please let us know if upgrading to newer version will fix it. We would like to evaluate the cost involved in upgrading to a newer version.

Hello Satish,

At “ComboBox / Load on Demand modes” demo you can observe the RadComboBox behavour with our latest version.
Additionally I can suggest you download a trial version of our latest release - Telerik.Web.UI.2011.3.1115  - from your account and test how your application works with it.

Best wishes,
Kalina
the Telerik team
