Decorate NumericValidationBehavior value

[stephenhauck]

Description

I am using a NumericValidationBehavior

And a converter to format the display ...
public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { return Decimal.Parse(value.ToString()).ToString("C"); }

How do I format the output for the user but validate the input ?

Hi @stephenhauck
that's a VERY good question :)

You will have to extend NumericValidationBehavior.

public class MoneyValidationBehavior : NumericValidationBehavior {
	protected override object? Decorate(object? value)
		=> base.Decorate(value)?.ToString()?.Replace("$", string.Empty);
}

And use MoneyValidationBehavior )

Thanks, that's awesome to know !
The code you posted was not compiling so it ended up looking like this

protected override object DecorateValue() => base.DecorateValue()?.ToString()?.Replace("$", string.Empty);

@stephenhauck oh... I guess you should use the latest pre-release version (or you will have to fix it in the future).
I made breaking change in this method. So it will be with parameter.
