Windows Phone 7 TextBox.Height = auto in code?

Question

How to set Textbox.Height to "auto" in Code? Thanks you

Answer 1

I believe Auto is Double.NaN

Update -

In addition to valid Double values, this property can also be Double.NaN. This way you determine the automatic size behavior in the code.
