SomeProperty/3
<SomeControl Value=\"{Binding ElementName=MyControl, Path=SomeProperty} / 3\"/>

：public class DivisionConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { int divideBy = int.Parse(parameter as string); double input = (double)value; return input / divideBy; } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { throw new NotSupportedException(); } }<!-- Created as resource --> <local:DivisionConverter x:Key=\"DivisionConverter\"/> <!-- Usage Example --> <TextBlock Text=\"{Binding SomeProperty, Converter={StaticResource DivisionConverter}, ConverterParameter=1}\"/> <TextBlock Text=\"{Binding SomeProperty, Converter={StaticResource DivisionConverter}, ConverterParameter=2}\"/> <TextBlock Text=\"{Binding SomeProperty, Converter={StaticResource DivisionConverter}, ConverterParameter=3}\"/>
