Data binding: One vs two way [closed]

Question

I don't currently have an example for my question. I would just like to get some insight of the following : When should one use one or two way data binding in XAML ?

Thank you in advance for the time you take to answer this !

Answer 1

In summary: use OneWay if the property is readonly, use TowWay if you want to change it from your view.

• 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.
