WPF Clear UserControl的孩子们

Question

I'm creating a UserControl in WPF, and the UserControl works so that when the user moves mouse over the control, it's childcontrols should be removed, but I don't seem to find the Children property or anything like that..

XAML is here:

<UserControl x:Class="myTextBox"
         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" 
         Name="thisTextBox"
         mc:Ignorable="d" d:DesignWidth="300" Height="57"     MouseEnter="UserControl_MouseEnter_1" MouseLeave="UserControl_MouseLeave_1">
<TextBlock Name="TypeText" TextWrapping="NoWrap" Text="" />
</UserControl>

And in code I need to do something like this to get the TextBlock go away:

private void UserControl_MouseEnter_1(object sender, MouseEventArgs e)
{
     Children.Clear(); // There is no such thing as children here!!!
}

The "child element" of the UserControl is contained in the Content property. You can set it to null in order to remove the content.

private void UserControl_MouseEnter_1(object sender, MouseEventArgs e)
{
    Content = null;
}
