WPF StringFormat={0:C} showing as dollars
Why does this line of code
<TextBlock Text="{Binding Net, StringFormat=c}"/>
Output the result as $xx.xx when all my regional settings are set to UK. I expect it to output it as £xx.xx. Any ideas? I have tried different variations of the stringformat including StringFormat={}{0:C} but still get the same result.
Thanks for looking.
Solution 1:
I'm not sure if this has been fixed in .NET 4, but WPF has never picked up the current culture when rendering things like currency or dates. It's something I consider a massive oversight, but thankfully is easily corrected.
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 excellent post for more information.
Solution 2:
I do Language="en-GB" in the main window e.g.
<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 in XAML @ Window level - 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 correctly picks up any custom regional settings. Although I'm using a manually created CultureInfo in the first step, I'm sure it's possible to pass in one of the static types - eg. System.Globalization.CultureInfo.CurrentCulture (I haven't tested it though...)
