WPF StringFormat = {0: C} showing as dollars

Question

Why is this line of code

<TextBlock Text="{Binding Net, StringFormat=c}"/> 

Print the result as $ xx.xx when all my regional settings are set in the UK. I expect him to print it as £ xx.xx. Any ideas? I have tried different variations of stringformat, including StringFormat = {} {0: C}, but still get the same result.

Thanks for watching.

I'm not sure if this was fixed in .NET 4, but WPF never raised the current culture when doing things like currency or dates. This is what I consider a huge oversight, but, fortunately, is easily fixed.

In your App class:

 protected override void OnStartup(StartupEventArgs e) { FrameworkElement.LanguageProperty.OverrideMetadata( typeof(FrameworkElement), new FrameworkPropertyMetadata( XmlLanguage.GetLanguage( CultureInfo.CurrentCulture.IetfLanguageTag))); base.OnStartup(e); } 

See this great post for more details.

I use Language = "en-GB" in the main window, for example.

 <Window x:Class="AllocateWPF.Vouchers" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Test" Height="692" Width="1000" Language="en-GB">

What works for me:
1) In app.xaml, override OnStartup () and add - System.Threading.Thread.CurrentThread.CurrentUICulture = new CultureInfo("et-EE");

2) Define at the XAML level @Window - xmlns:sysglb="clr-namespace:System.Globalization;assembly=mscorlib"

3) In XAML - <TextBox Text="{Binding Path=Price, StringFormat='{}{0:C}', ConverterCulture={x:Static sysglb:CultureInfo.CurrentUICulture}}" />

This one correctly selects the regional settings. . Although at the first stage I use the manually created CultureInfo, I am sure that you can pass one of the static types - for example. System.Globalization.CultureInfo.CurrentCulture (I have not tested it, though ...)
