Namespace: System.Windows.Data

Assembly: OpenSilver.dll

Syntax

public interface IMultiValueConverter

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.

Declaration

object Convert(object[] values, Type targetType, object parameter, CultureInfo culture)

Parameters

Type	Name	Description
System.Object[]	values	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.
System.Type	targetType	The type of the binding target property.
System.Object	parameter	The converter parameter to use.
System.Globalization.CultureInfo	culture	The culture to use in the converter.

Returns

Type	Description
System.Object	A converted value. If the method returns null, the valid null value is used. A return value of 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.

ConvertBack(Object, Type[], Object, CultureInfo)

Converts a binding target value to the source binding values.

Declaration
