Hi Simon,
I suppose you are using older version of RadComboBox. I suggest trying the latest service pack assemblies that were released a couple of weeks ago.

Hi Simon,
You could add an event handler to the MouseWheel event and in that handler set the IsDropDownOpen property of RadComboBox to true.

Maybe you did not understand what I said.I add an event handler to the MouseWheel event and in that handler set the IsDropDownOpen property of RadComboBox to true,but It is not what I want.Firstly,the popup open not as soon as I wheel the mouse;Secondly,I want it can scroll every item in the popup,like the mouse over the items from first to last,not only move the scroll bar.
Do you know what I mean?

Hi Simon,
I understand now. I tried to recreate your requirement and now I think that it is not currently possible with RadComboBox. First, when the dropdown is closed, on mouse wheel RadComboBox will try to change its selection and if it succeeds, it will handle the event, preventing the external event handler from executing (e.g. while the selection can be changed the event handler will not be executed and the dropdown cannot be open). On the other hand, when the dropdown is open, RadComboBox will not change its selection, but will only scroll its dropdown. Unfortunately both behaviors cannot be overridden or customized.
Sincerely yours,
