我已经定义了这样的东西

<ribbon:RibbonGroup Header="Size at Control Level">
                    <ribbon:RibbonControlGroup>
                        <ribbon:RibbonButton SmallImageSource="Images\wizard-icon16.png" LargeImageSource="Images\wizard-icon32.png" Label="Button 1">
                            <ribbon:RibbonButton.ControlSizeDefinition>
                                <ribbon:RibbonControlSizeDefinition ImageSize="Large" IsLabelVisible="True"></ribbon:RibbonControlSizeDefinition>
                            </ribbon:RibbonButton.ControlSizeDefinition>
                        </ribbon:RibbonButton>
                        <ribbon:RibbonButton SmallImageSource="Images\wizard-icon16.png" LargeImageSource="Images\wizard-icon32.png" Label="Button 2">
                            <ribbon:RibbonButton.ControlSizeDefinition>
                                <ribbon:RibbonControlSizeDefinition ImageSize="Small" IsLabelVisible="True"></ribbon:RibbonControlSizeDefinition>
                            </ribbon:RibbonButton.ControlSizeDefinition>
                        </ribbon:RibbonButton>
                        <ribbon:RibbonButton SmallImageSource="Images\wizard-icon16.png" LargeImageSource="Images\wizard-icon32.png" Label="Button 3"></ribbon:RibbonButton>
                        <ribbon:RibbonButton SmallImageSource="Images\wizard-icon16.png" LargeImageSource="Images\wizard-icon32.png" Label="Button 4"></ribbon:RibbonButton>
                    </ribbon:RibbonControlGroup>
                </ribbon:RibbonGroup>

但是所有按钮都很大.即使我为所有控件设置了一个带有Small的ControlSizeDefinition属性,它们仍然很大.我究竟做错了什么？

谢谢!
