WPF textblock binding with List

by

Convert your List to a single string with “\r\n” as the delimiter in between. and bind that to the TextBlock. Make sure that the TextBlock is not restricted with its height , so that it can grow based on the number of lines.
I would implement this as a Value Converter to XAML Binding which converts a List of strings to a single string with new line added in between

<TextBlock Text="{Binding Path=Logs,Converter={StaticResource ListToStringConverter}}"/>

The ListToStringConverter would look like this:

[ValueConversion(typeof(List<string>), typeof(string))]
public class ListToStringConverter : IValueConverter
{

    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        if (targetType != typeof(string))
            throw new InvalidOperationException("The target must be a String");

        return String.Join(", ", ((List<string>)value).ToArray());
    }

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