//得到Ribbon控件的值
[TransactionAttribute(Autodesk.Revit.Attributes.TransactionMode.Manual)]
public class cmdTest : IExternalCommand
{
    public Result Execute(ExternalCommandData commandData, ref string messages, ElementSet elements)
    {
        UIApplication uiApp = commandData.Application;
        Document doc = uiApp.ActiveUIDocument.Document;
        Selection sel = uiApp.ActiveUIDocument.Selection;

        Transaction ts = new Transaction(doc, "http://revit.5d6d.com");
        ts.Start();

        RibbonPanel ribbonPanel = null;
        List<RibbonPanel> listPanel = commandData.Application.GetRibbonPanels("Tab名称");
        foreach (RibbonPanel panel in listPanel)
        {
            if (panel.Name == "RibbonPanel名称")//RibbonPanel的Name
            {
                ribbonPanel = panel;
                break;
            }
        }
        
       
        IList<RibbonItem> listItem = ribbonPanel.GetItems();
        foreach (RibbonItem item in listItem)
        {
            if (item.Name == "Ribbon名字")//Ribbon的Name属性
            {
                item.Enabled = false;//false即为按钮变灰
            }
　　　　　　　
        }


        ts.Commit();
        return Result.Succeeded;
    }
}

如果是对按钮进行动态隐藏，只需将Enabled属性换成Visible就可以了。
