wpf Value and Multivalue Converters Group multiple converters [IValueConverter]
Example
This converter will chain multiple converters together.
public class ValueConverterGroup : List<IValueConverter>, IValueConverter
{
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
return this.Aggregate(value, (current, converter) => converter.Convert(current, targetType, parameter, culture));
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
throw new NotSupportedException();
}
}
In this example, the boolean result from EnumToBooleanConverter is used as input in BooleanToVisibilityConverter.
<local:ValueConverterGroup x:Key="EnumToVisibilityConverter">
<local:EnumToBooleanConverter/>
<local:BooleanToVisibilityConverter/>
</local:ValueConverterGroup>
The button will only be visible when the CurrentMode property is set to Ready.
<Button Content="Ok" Visibility="{Binding Path=CurrentMode, Converter={StaticResource EnumToVisibilityConverter}, ConverterParameter={x:Static local:Mode.Ready}"/>
