Close WPF popup when user clicks on it
提问by Michael Matejko
How do I close the following popup when its content is clicked?
单击其内容时如何关闭以下弹出窗口？
<Button Name="myButton" Content="Hover to open" />
<Popup PlacementTarget="{Binding ElementName=myButton}" Placement="Bottom">
<Popup.Resources>
<DataConversion:BooleanOrConverter x:Key="booleanOrConverter" />
</Popup.Resources>
<Popup.IsOpen>
<MultiBinding Mode="OneWay" Converter="{StaticResource booleanOrConverter}">
<Binding Mode="OneWay" ElementName="myButton" Path="IsMouseOver"/>
<Binding RelativeSource="{RelativeSource Self}" Path="IsMouseOver" />
</MultiBinding>
</Popup.IsOpen>
<!-- some content here -->
</Popup>
I wanted to avoid writing code in the code behind file and binding visual and behavioral things like IsOpen property or MouseDown event to the ViewModel.
我想避免在文件背后的代码中编写代码并将视觉和行为事物（如 IsOpen 属性或 MouseDown 事件）绑定到 ViewModel。

You need an EventTriggeron your Popupthat triggers a storyboard that contains a BooleanAnimationUsingKeyFramesthat sets IsOpento false, similar to this. Easier to just use code-behind ;o)
你需要一个EventTrigger在你的Popup触发包含一个故事板BooleanAnimationUsingKeyFrames，设置IsOpen到false，与此类似。更容易使用代码隐藏;o)

You could just make the Popup.Childa Button(style it to not look like one), handle its Clickevent and set IsOpento false(preferably using SetCurrentValueto not destroy the binding).
您可以只制作Popup.Childa Button（将其Click设置IsOpen为看起来不像一个），处理其事件并设置为false（最好使用SetCurrentValue不破坏绑定）。
You can either do this in code behind or using a behavior/trigger action.
您可以在后面的代码中执行此操作，也可以使用行为/触发器操作。
