#766 – WPF Data Binding Ignores Custom Formatting

You can get the WPF data binding engine to respect the current locale, as specified in the Region applet, by setting the Language property of a FrameworkElement to the language tag that is part of the CurrentCulture property.

Doing this allows you to set up the proper locale in a single line of code and data binding will use the correct rules for formatting dates and floating point numbers for the appropriate language.

This mechanism won’t, however, honor any custom formatting that you specify in the Region applet.  A custom format is anything that you change from the defaults in the Region applet.

If you want the data binding engine to completely respect all of the settings chosen in the Region applet, you can set the ConverterCulture property to the CurrentCulture, for each binding.

        <TextBlock Text="{Binding BoundDate, ConverterCulture={x:Static glob:CultureInfo.CurrentCulture}}"/>

The glob namespace points to System.Globalization.
