Can I constrain the Viewbox?

[HakanL]

I have a fixed size cell (in a Grid) that takes a TextBlock. I want to decrease the font size if the text is too large to fit with the default font size, so a Viewbox works wonder, however, if the text is really long then I'd like to just do TextTrimming as it's better to see part of the string than something so small you can't read any of it. Is it possible to constrain the child TextBlock to a minimum font size/scale and trigger an event so I can set the TextTrimming (or something along those lines)? I tried to create a subclass of the Viewbox but it's sealed so that didn't work. Any other suggestions?

Thanks for the question. Would MinWidth/MinHeight work for your scenario?

It will keep shrinking the font size until I can't read it any more. I needed a way to trim (TextTrimming) after a certain font size so at least the beginning of the text is readable.
