Exceptions
| Exception | Condition |

| InvalidOperationException | The Binding has already been attached to a target element, and cannot be modified. |
Remarks
In OneWay or TwoWay bindings, the source object must implement INotifyPropertyChanged in order for the target to update when the source changes.
See Binding Markup Extension to learn how Mode can be set as a binding property through the Binding markup extension, which enables specifying an entire Binding as an attribute string.

<TextBox x:Name="MyTextBox" Text="Text" Foreground="{Binding Brush1, Mode=OneWay}"/>
