WPF UserControl：单击 UserControl 对象时打开另一个 UserControl（弹出窗口）

Question

我在 User Control (FFU) 周围构建了一个按钮包装器，因此可以通过主 window 单击该对象。当FFU对象被点击时，我想再打开一个User Control: Popup FFU to be opened.

            DependencyProperty.Register("PopupFFUInstance", typeof(int), typeof(UC_FFU));

        public int PopupFFUInstance
        {
            get { return (int)GetValue(PopupFFUProperty); }
            set { SetValue(PopupFFUProperty, value); }
        }

        public UC_FFU()
                {
                    InitializeComponent();
        }
        
        //Added the Click Event
        public event RoutedEventHandler Click
        {
            add { Btn.AddHandler(ButtonBase.ClickEvent, value); }
            remove { Btn.AddHandler(ButtonBase.ClickEvent, value); } 
        }

        private void Btn_Click(object sender, RoutedEventArgs e)
        {
                  // Something to open the UserControl FFU Popup....
        }
    }
}

简单弹出示例 FFU XAML

<UserControl x:Class="HMI.Windows.UserControls.PopupControl.Popup_FFU"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

             xmlns:local="clr-namespace:HMI.Windows.UserControls.PopupControl"
             mc:Ignorable="d" 
             d:DesignHeight="50" d:DesignWidth="50">
    <Popup IsOpen="{Binding IsChecked, ElementName=button}" StaysOpen="False">
        <Border Background="LightYellow">
            <TextBlock>I'm the popup</TextBlock>
        </Border>
    </Popup>
</UserControl>

如何实现？

我试过像这样打开一个新的 window：但是它应该是一个弹出窗口。不是对话框 window。

Window window = new Window
            {
                Title = "My User Control Dialog",
                Content = new PopupControl.Popup_FFU()
            };

            window.Show();

这就是我要在您的代码中更改的内容。

UC_FFU.xaml: 把这个放在你结束之前 </Grid>

<Popup x:Name="ButtonPopup" StaysOpen="False">
    <UserControls:Popup_FFU />
</Popup>

UC_FFU.xaml.cs:

private void Btn_Click(object sender, RoutedEventArgs e)
{
    ButtonPopup.IsOpen = true;
}

Popup_FFU.xaml:

<UserControl x:Class="HMI.Windows.UserControls.PopupControl.Popup_FFU"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:local="clr-namespace:HMI.Windows.UserControls.PopupControl"
             mc:Ignorable="d" 
             d:DesignHeight="50" d:DesignWidth="50">
    <Border Background="LightYellow">
        <TextBlock>I'm the popup</TextBlock>
    </Border>
</UserControl>
