Determining the Enter key is pressed in a TextBox

Question

Consider a XAML TextBox in Win Phone 7.

The goal here is that when the user presses the Enter

Answer 1

You'll be looking to implement the KeyDown event specific to that textbox, and checking the KeyEventArgs for the actual Key pressed (and if it matches Key.Enter, do something)

private void Box_KeyDown(object sender, KeyEventArgs e)
{
    if (e.Key.Equals(Key.Enter))
    {
        //Do something
    }
}

Just a note that in the Beta version of the WP7 emulator, although using the software on-screen keyboard detects the Enter key correctly, if you're using the hardware keyboard (activated by pressing Pause/Break), the Enter key seems to come through as Key.Unknown - or at least, it was doing so on my computer...
