Put textbox in uppercase in XAML for windows 8.1

One textbox in a page. i can not use the converter (it is not worked) and I can not use CharacterCasing property How can I put in uppercase my Textbox when i write a text ?

I use Windows runtime to develop for Windows 8.1 so I do not find many help on the internet

My code for the moment :

KeyUp :

String str = "hello";
str = str.ToUpper();
str.Select(str.Count(), 0);

KeyDown :

bool bModify = true;

My XAML code :

<TextBox Name="Name" KeyUp="KeyUp" FontSize="20" Margin="15" Grid.Column="1" Grid.Row="0" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" KeyDown="KeyDown"/>

You could leave the TextBox as is, but when not in focus - hide it and show a TextBlock instead with the same text, but with something like Typography.Capitals="SmallCaps" set.

Otherwise - this might work:

<TextBox
    x:Name="tb"
    Width="500"
    VerticalAlignment="Center"
    HorizontalAlignment="Center"
    KeyDown="OnKeyDown"
    TextChanged="OnTextChanged"/>

C#

private void OnKeyDown(object sender, KeyRoutedEventArgs e)
{
    DoTheAllCapsThing();
}

private void OnTextChanged(object sender, TextChangedEventArgs e)
{
    DoTheAllCapsThing();
}

private void DoTheAllCapsThing()
{
    var start = tb.SelectionStart;
    var length = tb.SelectionLength;
    tb.Text = tb.Text.ToUpper();
    tb.Select(start, length);
}
