Creating a bindable Point in C# WPF

Question

I know multiple inheritence is out, but is there a way to create a wrapper for System.Windows.Point that can inherit from it but still implement bindable dependency properties?<

Answer 1

Unfortunately, Point is a struct, and structs don't support inheritance. From MSDN

Note Structs do not support inheritance, but they can implement interfaces. For more information, see Interfaces (C# Programming Guide).

Maybe this doesn't answer your question directly but you can easily bind a Point with the help of a Converter. In your case it would be like

PointConverter

public class PointConverter : IMultiValueConverter
{
    public object Convert(object[] values, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        double xValue = (double)values[0];
        double yValue = (double)values[1];
        return new Point(xValue, yValue);
    }
    public object[] ConvertBack(object value, Type[] targetTypes, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

If you just want to bind the X value and have a static Y value you could do this like

PointXConverter

public class PointXConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        double progressBarValue = (double)value;
        double yValue = System.Convert.ToDouble(parameter);
        return new Point(progressBarValue, yValue);
    }
    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}
