Syntax

public class CalculateDoubleConverter : IValueConverter, IMultiValueConverter

Remarks

Values and parameters provided to this converter must be IConvertible. If any value or parameter is not IConvertible 1 will be assumed as its value.

The converter can ConvertBack(object, Type, object, CultureInfo) if used as IValueConverter. As IMultiValueConverter ConvertBack(object, Type[], object, CultureInfo) is not possible. It will throw an NotSupportedException.

Type	Description
CalcOperation	The operation.

Methods

View Source

Convert(object, Type, object, CultureInfo)

Converts a value.

Declaration

public object Convert(object value, Type targetType, object parameter, CultureInfo culture)

Parameters

Type	Name	Description
object	value	The value produced by the binding source.
Type	targetType	The type of the binding target property.
object	parameter	The converter parameter to use.
CultureInfo	culture	The culture to use in the converter.

Returns

Type	Description
object	A converted value. If the method returns null, the valid null value is used.

View Source

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

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

Parameters

Type	Name	Description
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.
Type	targetType	The type of the binding target property.
object	parameter	The converter parameter to use.
CultureInfo	culture	The culture to use in the converter.

Returns

Type	Description
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.

View Source

ConvertBack(object, Type, object, CultureInfo)

Converts a value.

Declaration

public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)

Parameters

Type	Name	Description
object	value	The value that is produced by the binding target.
Type	targetType	The type to convert to.
object	parameter	The converter parameter to use.
CultureInfo	culture	The culture to use in the converter.

Returns

Type	Description
object	A converted value. If the method returns null, the valid null value is used.

View Source

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

Converts a binding target value to the source binding values.

Declaration

public object[] ConvertBack(object value, Type[] targetTypes, object parameter, CultureInfo culture)

Parameters

Type	Name	Description
object	value	The value that the binding target produces.
Type[]	targetTypes	The array of types to convert to. The array length indicates the number and types of values that are suggested for the method to return.
object	parameter	The converter parameter to use.
CultureInfo	culture	The culture to use in the converter.

Returns

Type	Description
object[]	An array of values that have been converted from the target value back to the source values.
