using CodeStack.SwEx.Properties;
using SolidWorks.Interop.swconst;

public class ComboBoxDataModel
{
    public enum Options_e
    {
        Option1,
        Option2,
        Option3
    }

    [ComboBoxOptions(swPropMgrPageComboBoxStyle_e.swPropMgrPageComboBoxStyle_Sorted)]
    public Options_e Options { get; set; }
}

Additional options and style for combo box control can be specified via ComboBoxOptionsAttribute
