WPF: RibbonGalleryCategory和IsSynchronizedWithCurrentItem

Question

我有RibbonControlsLibrary的功能区菜单。我有RibbonGalleryCategory：

<RibbonGalleryCategory Header="Recent Documents" 
                       ItemsSource="{Binding RecentDocuments}">
...
</RibbonGalleryCategory>

如何将所选项目与MVVM同步？如何在ICommand上绑定选定项？RibbonGalleryCategory.IsSynchronizedWithCurrentItem不存在。

Answer 1

您的RibbonGalleryCategory需要是RibbonGallery的一部分。您可以在上面设置选定的项目。

<RibbonGallery SelectedItem="RecentDocument">
    <RibbonGalleryCategory Header="Recent Documents"
                           ItemsSource="{Binding RecentDocuments}">
    ...
    </RibbonGalleryCategory>
</RibbonGallery>
