Property Value
Type | Description |
---|---|
FallbackBehavior | The fallback behavior of this |
Remarks
The fallback behavior determines how this MapConverter
treats failed conversions. ReturnUnsetValue
(the default)
specifies that any failed conversions should return System.Windows.DependencyProperty.UnsetValue, which can be used in combination with
Binding.FallbackValue
to default bindings to a specific value.
Alternatively, FallbackBehavior.ReturnOriginalValue
can be specified so that failed conversions result in the original value
being returned. This is useful where mappings are only necessary for a subset of the total possible values. Mappings can be specified
where necessary and other values can be returned as is by the MapConverter
by setting the fallback behavior to
ReturnOriginalValue
.
