我正在尝试在应用程序中使用RibbonGallery，但是在加载包含图库的选项卡时，在运行时出现此错误:

I am trying to use a RibbonGallery in my application, but I get this error at runtime, when the tab which contains the gallery is loaded:

有什么不对的地方吗?

代码如下:

<ribbon:RibbonGallery MaxColumnCount="1">
                        <ribbon:RibbonGalleryCategory>
                            <ribbon:RibbonGalleryItem Content="Green" Foreground="Green" />
                            <ribbon:RibbonGalleryItem Content="Blue" Foreground="Blue" />
                            <ribbon:RibbonGalleryItem Content="Orange" Foreground="Orange" />
                        </ribbon:RibbonGalleryCategory>
                    </ribbon:RibbonGallery>

推荐答案

RibbonGallery控件必须放置在可以利用RibbonGallery优势的控件中，例如RibbonSplitButton或RibbonComboBox.这是在RibbonComboBox中使用画廊的示例:

The RibbonGallery control must be placed within a control that can take advantage of the RibbonGallery, like a RibbonSplitButton or a RibbonComboBox. Here is an example of using a gallery in a RibbonComboBox:

<ribbon:RibbonComboBox Label="1"
                  SmallImageSource="Images/RightArrowShort_Green16.png"
                  SelectionBoxWidth="62"
                  VerticalAlignment="Center"
                  IsEditable="True" >
    <ribbon:RibbonGallery SelectedValue="Green"
                          SelectedValuePath="Content"
                          MaxColumnCount="1">
        <ribbon:RibbonGalleryCategory>
            <ribbon:RibbonGalleryItem Content="Green" Foreground="Green" />
            <ribbon:RibbonGalleryItem Content="Blue" Foreground="Blue" />
            <ribbon:RibbonGalleryItem Content="Orange" Foreground="Orange" />
        </ribbon:RibbonGalleryCategory>
    </ribbon:RibbonGallery>
</ribbon:RibbonComboBox>

从 http://msdn复制的

XAML .microsoft.com/en-us/library/microsoft.windows.controls.ribbon.ribbongallery.aspx .

如果控件是从RibbonMenuButton派生的，则由于具有HasRibbon属性，它可以包含RibbonGallery.

If a control is derived from RibbonMenuButton then it can contain a RibbonGallery because of the HasRibbon property.
