WP7 Autosize TextBlock to Maximum

Is there a way to set the font size of a TextBlock to the maximum allowed for the space available?

Here is a snippet of the code;

<Grid x:Name="LayoutRoot" Background="Transparent">
    <Grid HorizontalAlignment="Center" VerticalAlignment="Center">
        <TextBlock x:Name="myText" Text="Grow Me" TextAlignment="Center">
        </TextBlock>
    </Grid>
</Grid>

I'd like some think like FontSize=Auto|Maximum but they don't exist.

Thanks, Mike

EDIT: Here is the working code;

Thanks for pointing me in the right direction Allen.

while (myText.RenderSize.Width <= 450)
{
    myText.FontSize += 1;
    myText.UpdateLayout(); //Need this otherwise RenderSize doesn't change
}

Maybe the Viewbox was not available in May, but it is available now in November.

Thanks for the hint

The automatic way to do this is with a ViewBox but, unfortunately, this isn't available on the phone.

You'll have to resize the text yourself. :(

you can listen to the outter Grid's SizeChanged event.

Keep incrementing or decrementing your textblock font size until your TextBlock's rendered size is close to outter Grid's size.
