Scaling text with Viewbox

Hi All,

My UI requirement calls for multiple TextBlocks to scale within a Window. Not a problem, wrap them in a Viewbox - works great.

Here's my problem; The requirement states the font size must be the same in all TextBlocks. What that means to me is the largest font needs to scale down to the smallest font.

The following XAML file illustrates my issue. "Hello World" will be a much shorter size than "Hello" if I resize the Window to be narrow and tall.

Any ideas on how to achieve this?

I have a List<> of all Viewboxes, max is 8. I can set MaxHeight on a SizeChanged event on all of them, but I get stuck there.

Any help would be greatly appreciated.

Thanks in advance,

Jason
