为什么用户控件加载事件没有被触发

我有一个用户控件。我有时再次遇到这种情况，但总是可以通过使用“New() 构造函数”来修复它。但我仍然想知道我做错了什么，因为如果加载控件，则必须触发加载事件！

这是一些代码：

<Window x:Class="MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:my="clr-namespace:OUTPUT___VideoContent"
    Title="OUTPUT - VideoContent" Height="350" Width="525" Icon="/OUTPUT%20-%20VideoContent;component/Images/VideoContent.png">
    <Grid x:Name="LayoutRoot">
        <Grid x:Name="VideoGrid">
            <my:ucVideoPresenter x:Name="VideoPresenter1"/>
            <TextBlock x:Name="txtInfo" Visibility="Collapsed" />
        </Grid>
    </Grid>
</Window>

在用户控件中，在 WPF 或代码行为上声明加载事件，但没有成功！用户控制 wpf

I have a user control. I had this situations again some times but could always fix it by using the "New() contructor". But I still wonder what I am doing wrong because the load event has to be fired if control was loaded!

Here is some code:

<Window x:Class="MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:my="clr-namespace:OUTPUT___VideoContent"
    Title="OUTPUT - VideoContent" Height="350" Width="525" Icon="/OUTPUT%20-%20VideoContent;component/Images/VideoContent.png">
    <Grid x:Name="LayoutRoot">
        <Grid x:Name="VideoGrid">
            <my:ucVideoPresenter x:Name="VideoPresenter1"/>
            <TextBlock x:Name="txtInfo" Visibility="Collapsed" />
        </Grid>
    </Grid>
</Window>

and in the usercontrol, the load event is declared on WPF or codebehing without any success!
Usercontrol wpf

Usercontrol codebehind
