I'm developing a WPF control that contains a popup.
我正在开发一个包含弹出窗口的WPF控件。
The popup is placed relatively to an element that is draggable. This element can be positioned around the edges of the screen. So every time I open the popup I need to determine whether it will fit on the screen or it will be automatically repositioned.
弹出窗口相对于可拖动的元素放置。该元素可以位于屏幕边缘周围。因此，每次打开弹出窗口时，我都需要确定它是否适合屏幕，否则它将自动重新定位。
How can I achieve this?

It is possible to centre a pop-up for example in the middle of your screen. Based on what you typed and on your tags I assume you need XAML to center a popupscreen.
例如，可以在屏幕中间居中显示弹出窗口。根据您输入的内容和标签，我假设您需要XAML来固定弹出屏幕。
you can do it like this: <Popup x:Name="ParentPopup" PlacementTarget="{Binding ElementName=MainPanel}" Placement="Center" />
