SelectedView是从Xam选项卡控件绑定到选定视图的属性。
XAML公司
<ToolBar DataContext="{Binding SelectedView.ViewModel}"
ItemsSource="{Binding ContextualButtons}" >
<ToolBar.ItemTemplate>
<DataTemplate>
<!-- <Button ToolTip="{Binding Name}"-->
<!-- Command="{Binding Command}">-->
<!-- <Button.Content>-->
<!-- <Image Width="32" Height="32" Source="{Binding ImageSource}"/>-->
<!-- </Button.Content>-->
<!-- </Button>-->
<Button Content="{Binding Name}"/>
</DataTemplate>
</ToolBar.ItemTemplate>
</ToolBar>
