When you set a value for the property, it must be equal to or greater than 0.0. Set this property to NaN ("Auto" in XAML) to make the row header automatically adjust its size to fit its content.
Double::PositiveInfinity is not a valid value for this property. The value restrictions on the Double value are enforced by a ValidateValueCallback mechanism. If you attempt to set a value that is not valid, a run-time exception is thrown.
