Conditional Resources Creation WPF XAML Design / Run time

Question

Following a first question on WPF Cascading Binding,

I remarked that I had more Resources than desired defined in both the MainWindow

Answer 1

I prepared simplified way out displaying one data during design time and latter during run time. Hopefully you will find it useful and adjust to your case.

XAML:

Converter:

 class IsInDesignModeConverter : IMultiValueConverter
{
    public object Convert(object[] values, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        if ((bool)(DesignerProperties.IsInDesignModeProperty.GetMetadata(typeof(DependencyObject)).DefaultValue))
            return values[0];
        return values[1];
    }

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

As a result it display Design mode text during design time and Run time when running. In your case instead of TextBlock you can insert already defined resources.
