WPF doesn't honor Textbox.MinLines for Auto height calculation

Question

I want to have a TextBox which Height grows as Iam entering lines of Text.

I've set the Height property to "Auto", and so far the growing works. Now I want that the TextBox's Height should be at least 5 lines. Now I've set the MinLines property to "5" but if I start the app the TextBox's height is still one line.

Answer 1

Try setting the MinHeight property.
