Set global cultureinfo for decimal values

Question

How to set CultureInfo globally for all decimal values.

Take one decimal value like

15.00

we may use DecimalValue.ToString("C", new CultureInfo("en-GB"))

so that it will convert for that culture and output is

€15.00

But the question is am I able to Set the culture info for all decimal values that are going to display in the project?

You might consider implementing a custom value converter (https://learn.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/data-binding/converters) and dealing with the issue at the presentation, e.g.: — Maxim Saplin, Dec 10 '18 at 14:25

Your better approach is too declare a converter for Decimal values, and use it wherever you need to display the values.

First you write your converter:

public class DecimalConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            if (value == null)
                return "0";
            decimal decimalValue = (decimal)value;
            return decimalValue.ToString("C", new CultureInfo("en-GB"))
        }

        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
        {
            throw new NotImplementedException();
        }
    }

then, in your App.xaml.cs, inside ResourceDictionary you declare it to use it in your application

Now, in your pages, wherever you bind decimal values, you can use it like this:

   <Label Text="{Binding YourDecimalValue, Converter={StaticResource DecimalConverter}}"/>
