Mode in WPF

You use the Mode property to specify the direction of the binding. The following enumeration list shows the available options for binding updates:

• TwoWay updates the target property or the property whenever either the target property or the source property changes.
• OneWay updates the target property only when the source property changes.
• OneTime updates the target property only when the application starts or when the DataContext undergoes a change.
• OneWayToSource updates the source property when the target property changes.
• Default causes the default Mode value of target property to be used.
