Accessing User Control Properties

Question

Hi, I have created a UserControl as follows:

<UserControl
    x:Class="MySample.MyControl"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:MySample"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d"
    d:DesignHeight="300"
    d:DesignWidth="400">

    <Canvas>
        
        <Ellipse Width="150" Height="150"/>
                    
        <TextBlock>Sample</TextBlock>

    </Canvas>

</UserControl>

In my main page I instantiate it as follows:

<local:MyControl x:Name="MyControl" Margin="100,50 0,0"></local:MyControl>

Now, I would like to change the text of my Control to "Hello World". In the ctor of MainPage I tried:

MainPage::MainPage()
{
	InitializeComponent();

MyControl->Text = "Hello World";
}

But MyControl does not seem to be recognized here. Any idea ?
