InverseConverter Class
Represents a value converter that inverts another value converter.
public class InverseConverter- Inheritance:
- object object
Remarks
This converter allows the logic of existing value converters to be reused in bindings that require the data conversion
to be reversed. For example, if AToBConverter converts type A to type B, then wrapping it with an instance of
InverseConverter it will convert from type B to type A. This allows AToBConverter to be used in a binding
for properties of type A.
Examples

Methods
Convert(object, Type, object, CultureInfo)
Converts a value. The data binding engine calls this method when it propagates a value from the binding source to the binding target.
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)| Parameter | Type | Description |
|---|---|---|
| value | object | The value produced by the binding source. |
| targetType | Type | The type of the binding target property. |
| parameter | object | The converter parameter to use. |
| culture | CultureInfo | The culture to use in the converter. |
Returns
- object:
A converted value.
ConvertBack(object, Type, object, CultureInfo)
Converts a value. The data binding engine calls this method when it propagates a value from the binding target to the binding source.
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)| Parameter | Type | Description |
|---|---|---|
| value | object | The value produced by the binding source. |
| targetType | Type | The type of the binding target property. |
| parameter | object | The converter parameter to use. |
| culture | CultureInfo | The culture to use in the converter. |
Returns
- object:
A converted value.
