Hello Andreas,

Thank you for the feedback.

Presuming  that you are referring to the issue in regards to the missing AM/PM identifier, please note that it is available for the "en-US" culture only.

In order to apply the AM/PM identifier when the culture is set to german, I can suggest you create a converter for the respective field by returning the DateTime value as a string representation with the "en-US" culture.

public class TimeConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        return (value != null) ? ((DateTime)value).ToString(@"hh:mm:ss tt", new CultureInfo("en-US"))
                                : Binding.DoNothing;
    }

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

I have modified the sample application you have provided by demonstrating the approach from above.

If you have any questions, please let me know.

The behavior at my application is different. Please set the culture to:

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

The culture of my application is not in every case "en-US". If i set the culture to "en-US" the output looks like yours.

At the test solution alternate binding is not neccessary but in the application who i create it is.

Thanks.
