Question

I have often used TextBox to bind to Integers without much problem.

However if I try to bind a TextBox to a Double it doesn’t work.

When I type 5,85 ( , being my cultures decimalSeperator) I pass 585.0 to the double value.

How is it being converted and what solution could I use to fix this? Would a ValueConverter be the best solution?

You could try adding this to your application’s constructor:

FrameworkElement.LanguageProperty.OverrideMetadata(typeof(FrameworkElement),
             new FrameworkPropertyMetadata(XmlLanguage.GetLanguage(CultureInfo.CurrentCulture.IetfLanguageTag)));

However, please note that this will not work if you customize the decimal separator. (WPF double valued data binding with custom decimal separator)
