C# 为什么UserControle不可见？

我尝试将边界作为我与WPF合作的通知。因此，我创建了UserControle表示通知卡，下面是Xaml代码：

<UserControl x:Class="Try2.OurNotification"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    <Border Name="BrdNotifay" Style="{StaticResource {ComponentResourceKey

    <DockPanel Margin="5">
        <TextBlock DockPanel.Dock="Left" Style="{StaticResource

                </Canvas>
        </TextBlock>
        <StackPanel DockPanel.Dock="Right">
            <TextBlock Text="{Binding Title, RelativeSource={RelativeSource

                       Style="{StaticResource {ComponentResourceKey

            <TextBlock Text="{Binding Message, RelativeSource= 
 {RelativeSource AncestorType=Try2:OurNotification, Mode=FindAncestor}}"
                       Style="{StaticResource {ComponentResourceKey 
 TypeInTargetAssembly={x:Type Try2:ThemeKey}, ResourceId=ToastMessage}}" />
        </StackPanel>
        </DockPanel>
    </Border>
 </UserControl> 

我有主题词典和“themekey”课程来改变主题， 我创建了类“NotifiayDefinitions.cs”，它包含所有需要的定义和动画方法。这是代码

    public static SolidColorBrush ToSolidColorBrush(this string hex)
    {
        var convertFromString = ColorConverter.ConvertFromString(hex);
        var color = (Color?)convertFromString ?? Colors.Black;
        return new SolidColorBrush(color);
    }

                DoubleAnimationUsingKeyFrames growfrombottom = new DoubleAnimationUsingKeyFrames();
                growfrombottom.KeyFrames.Add(new SplineDoubleKeyFrame(0, TimeSpan.FromSeconds(0)));
                growfrombottom.KeyFrames.Add(new SplineDoubleKeyFrame(1, TimeSpan.FromSeconds(1.5)));
                growfrombottom.KeyFrames.Add(new SplineDoubleKeyFrame(1, TimeSpan.FromSeconds(4)));
                growfrombottom.KeyFrames.Add(new SplineDoubleKeyFrame(0, TimeSpan.FromSeconds(5.5)));
                Storyboard.SetTargetProperty(growfrombottom,
                    new PropertyPath("RenderTransform.(ScaleTransform.ScaleY)"));
                story.Children.Add(growfrombottom);
                break;
        }

        return story;
    }


}

}

然后我创建了名为“callNotifications.cs”的调用来更改通知卡的颜色和图标，我在这里称它为“callNotifications.cs”的代码

}

最后，我转到“mainwindow”，并调用负责这里出现的通知类型的方法

            CallNotifiactions.ShowError(this, "Error", "Boof", ToasterAnimation.SlideInFromTop, 10);

代码运行良好，但“UserControle”不可见，我也不明白为什么通知不可见？ 哪里出了错

我希望能帮助我

谢谢。

请解释您试图做什么，以及在什么情况下您的“UserControle”不可见。另外，请只添加此问题所需的代码。我试图将“UserControle”显示为一个与此代码相关的通知，代码正常工作，但“UserControle”未显示在主窗口中
