How to force a focused Textbox binding to update when I tap an app bar item

This technical article explains a common Windows Phone development problem: two-way TextBox bindings don't update when an app bar item is tapped because the TextBox doesn't lose focus. It provides a detailed C# code solution using FocusManager to force the binding source to update, extending the fix to PasswordBox controls, and mentions alternative fixes in toolkits like Caliburn.Micro.
