How do I set `ShowObjectMenu=false` on UniGrid from `Object Listing` template of Custom Module UI?

Would anyone here happen to know how to remove the Action/Object menu from a UniGrid when implementing the Object Listing UI template for a custom module?I've tried setting Control.ShowObjectMenu = false from the OnInit method of my ControlExtender class as illustrated in the @creating extenders for module interfaces pages@ documentation.I've also tried adding @key name=@ShowObjectMenu@ value=@false@ /@ to the @options@ section of the UniGrid definition XML as the documentation suggests might be possible in the UniGrid definition reference.Because I'm utilizing an Object Listing template, I don't have an ASCX layout to set the ShowObjectMenu property from, so I think it has to be from the Control Extender class. Perhaps I need to do this from one of the Control events other than OnInit()?
