WPF resizing TextBlock

Question

I have a textblock in a grid in WPF.

I want the text to dynamically size (font) when resized. At the moment textboxes, comboboxes do this, but the the textblock stays the same. Is it possible?

Answer 1

Instead of trying to manually rig a TextBlock to do this, just edit the default template of a TextBox and remove the border and background, then in the style make it set the IsReadOnly flag. This way you get the textblock sizing, as well as copy-paste for free.

Answer 2

use expression blend for getting the default template of TextBox, then you can edit it as you required.
