Can I set a C1 Combo/DropDown control without using the <control>.Keys action?

The Test application I am working on contains a ComponentOne DropDown or ComboBox control (I'm not certain) extended as user-defined wrapper control called agxDropDown. I am wondering if TestComplete provides support to set this control by sending in the value of the item in the drop down list without using the <control>.Keys action? Using this action causes some unwanted pop ups to occur that I would like to avoid if possible. I didn't see anywhere on your website that TestComplete provides support for ComponentOne controls other than menus and tooltips.  I tried using the <control>.ClickItem action.  However I get an error that TC is unable to find the object ClickItem(<value>).  Any suggestions?  Thank you.
