Question

I have a page in my WP7 which contains some text boxes. When pressing the back key this method is run to save the contents:

 protected override void OnBackKeyPress(System.ComponentModel.CancelEventArgs e)
    {
        var settings = IsolatedStorageSettings.ApplicationSettings;

        settings["remZone"] = txtBoxZone.Text;
        settings["remSpace"] = txtBoxSpace.Text;
    }

The problem is some users would not press the back button, but would press the home button to exit the app, so the contents are not saved.

I think there are two avenues round this if possible:
1. Is there a function that would run this method when the home button is pressed, like the onBackKeyPress.
2. Is there a simple way to save the contents of the text box as the user is entering it?

Thanks.

EDIT:

solution was this:

   protected override void OnNavigatingFrom(NavigatingCancelEventArgs e)
     {
         var settings = IsolatedStorageSettings.ApplicationSettings;

         settings["remZone"] = txtBoxZone.Text;
         settings["remSpace"] = txtBoxSpace.Text;
     }

Answer 1

The simplest solution to your problem would be overriding Page.OnNavigatingFrom method.
