Public Function ConvertBack (value As Object, targetTypes As Type(), parameter As Object, culture As CultureInfo) As Object()
The value that the binding target produces.
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.
The converter parameter to use.
The culture to use in the converter.
An array of values that have been converted from the target value back to the source values.
If there are more return values than there are bindings in the MultiBinding, the excess return values are ignored. If there are more source bindings than there are return values, the remaining source bindings do not have any values set on them. Types of return values are not verified against
targetTypes; the values are set on the source bindings directly.
Return DoNothing at position
i to indicate that no value is to be set on the source binding at index
Return DependencyProperty.UnsetValue at position
i to indicate that the converter is unable to provide a value for the source binding at index
i, and that no value is to be set on it.
null to indicate that the converter cannot perform the conversion or that it does not support conversion in this direction.
