title: TextBox Binding TwoWay Doesn't Update Until Focus Lost WP7
body: <p>I have a page with some text boxes for data input. The binding of the text box is set to <code>TwoWay</code>. The data in my view model only gets updated if the text box loses focus. If I click a button, such as save, and the text box still has the focus, the changes in the text box aren't changed in my view model on the save event.</p>
  
  <p>Is there a way to have the binding save the value of the text box before it loses focus? Or do I need to do something in the save event? </p>
