Gets or sets the RibbonDropDownItem that is currently selected.
Assembly: Microsoft.Office.Tools.Common (in Microsoft.Office.Tools.Common.dll)
Setting this property to a RibbonDropDownItem causes the item to appear in the text box portion of the drop-down list. The RibbonDropDownItem reference that you assign to the property must exist in this RibbonDropDown object's Items collection. Otherwise, an ArgumentException will be thrown.
Assigning a new value to the property does not cause a SelectionChanged event to be raised.
