Returns
| Type | Description |
|---|---|
| object | Converted back value. Binding.DoNothing may be returned to indicate that no value should be set on the source property. System.Windows.DependencyProperty.UnsetValue may be returned to indicate that the converter is unable to provide a value for the source property, and no value will be set to it. |
Remarks
The data binding engine does not catch exceptions thrown by a user-supplied converter. Thus any exception thrown by ConvertBack, or thrown by methods it calls and not caught by the ConvertBack, will be treated as a runtime error (i.e. a crash). ConvertBack should handle anticipated problems by returning DependencyProperty.UnsetValue.
