若要复制，请下载并安装Microsoft Ribbon for WPF。如何在用户单击RibbonButton时用StaysOpen = false显示弹出菜单
我需要显示弹出窗口当用户点击RibbonButton。此外，我需要隐藏弹出窗口当用户点击任何地方，但弹出窗口，所以我将不得不将StaysOpen属性设置为虚假。
我已经创建了一个新的WPF Ribbon应用程序。在那之后，我改变了默认MainWindow.xaml实现这样的：
<Grid x:Name="LayoutRoot">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<ribbon:Ribbon x:Name="Ribbon">
<ribbon:Ribbon.ApplicationMenu>
<ribbon:RibbonApplicationMenu SmallImageSource="Images\SmallIcon.png">
<ribbon:RibbonApplicationMenuItem Header="Hello _Ribbon"
x:Name="MenuItem1"
ImageSource="Images\LargeIcon.png"/>
</ribbon:RibbonApplicationMenu>
</ribbon:Ribbon.ApplicationMenu>
<ribbon:RibbonTab x:Name="HomeTab"
Header="Home">
<ribbon:RibbonGroup x:Name="Group1"
Header="Group1">
<ribbon:RibbonButton x:Name="Button1"
LargeImageSource="Images\LargeIcon.png"
Label="Button1"
Click="Button1_Click"/>
<Popup PlacementTarget="{Binding ElementName=Button1}"
StaysOpen="False"
Name="p">
<TextBlock Background="Green" Text="Popup Text" />
</Popup>
<Button Click="Button1_Click" Content="Open popup" />
</ribbon:RibbonGroup>
</ribbon:RibbonTab>
</ribbon:Ribbon>
</Grid>
和MainWindow.xaml.cs：
public partial class MainWindow : RibbonWindow
{
public MainWindow()
{
InitializeComponent();
// Insert code required on object creation below this point.
p.Opened += new EventHandler(p_Opened);
p.Closed += new EventHandler(p_Closed);
}
void p_Closed(object sender, EventArgs e)
{
System.Diagnostics.Debug.Print("closed");
}
void p_Opened(object sender, EventArgs e)
{
System.Diagnostics.Debug.Print("opened");
}
private void Button1_Click(object sender, RoutedEventArgs e)
{
p.IsOpen = true;
}
}
当我启动应用程序，点击普通按钮，我可以看到Popup。但是当我点击RibbonButton时，我再也看不到它了。我可以在Output窗口看到Opened事件Popup被提出，但随即立即Closed事件Popup被提出。
