Setting TextBox.Width = "*" via code

Question

Does anyone know how to set the TextBox.Width property to fill the rest of the parent container in the code? In Xaml, I would just set the Width property to *, but I cannot figure out how to do this in code.

Thanks Roy

You are looking for

HorizontalAlignment="Stretch"

Horizontal alignment = alignment with stretch, maximum width and left edge at the same time?

Answer 2

Try to execute

textBox.Width = Double.NaN;

Double.NaN (not a number) is the equivalent of any size.
