验证@ WPF Textbox后删除了小数

Question

I create a Textbox in Code behinde and bind it to a double Property.

                TextBox t = new TextBox();
                t.Width = 80;
                t.DataContext = s;         
                Binding binding = new Binding();
                binding.Mode = BindingMode.TwoWay;
                binding.Path = new PropertyPath("Value");
                BindingOperations.SetBinding(t, TextBox.TextProperty, binding);

When i enter a value like 45,45 (comma) it is parsed to 4545.

If i enter 45.45 (point) it is parsed correct with 45,45.

I use German language Settings and my decimal Sperator is ,

What am i doing wrong?

Answer 1

Try setting binding. ConverterCulture to your target culture.

For example

 binding.ConverterCulture = CultureInfo.CurrentCulture;

Answer 2

A clear, not culture specific solution is to add this to your App.xaml.cs and normally WPF will always use the correct culture - regional settings:

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

Answer 3

Did you tried

System.Threading.Thread.CurrentThread.CurrentCulture = new CultureInfo("de-DE");
System.Threading.Thread.CurrentThread.CurrentUICulture = new CultureInfo("de-DE");
