Methods
Convert(object[], Type, object, CultureInfo)
Converts source values to a value for the binding target. The data binding engine calls this method when it propagates the values from source bindings to the binding target.
public abstract object Convert(object[] values, Type targetType, object parameter, CultureInfo culture)
Parameters
values
object[]The array of values that the source bindings in the MultiBinding produces. The value UnsetValue indicates that the source binding has no value to provide for conversion.
targetType
TypeThe type of the binding target property.
parameter
objectThe converter parameter to use.
culture
CultureInfoThe culture to use in the converter.
Returns
- object
A converted value.
If the method returns null, the valid null value is used.
A return value of DependencyProperty.UnsetValue indicates that the converter did not produce a value, and that the binding will use the FallbackValue if it is available, or else will use the default value.
A return value of Binding.DoNothing indicates that the binding does not transfer the value or use the FallbackValue or the default value.
ConvertBack(object, Type[], object, CultureInfo)
Converts a binding target value to the source binding values.
