How do you get a submit button in the Windows Phone keyboard?

Question

I want the white arrow to appear in my text input boxes so users have a way of forward other than tapping away from the keyboard or using the hardware Back button.

Answer 1

Instead of handling the TextChanged method, handle the KeyUp method of the Textbox:

private void InputBox_KeyUp(object sender, System.Windows.Input.KeyEventArgs e)
{
      if (e.Key == Key.Enter)
      {
           //enter has been pressed
      }
}

Answer 2

Also, I found that to get the white submit button that the search box has you can set the InputScope to "search":

<TextBox x:Name="InputBox" InputScope="Search" AcceptsReturn="False" KeyUp="InputBox_KeyUp"/>

I still haven't figured out if this has any unintended side-effects.

For good measure here is the code to dismiss the keyboard in the KeyUp event:

void InputBox_KeyUp(object sender, System.Windows.Input.KeyEventArgs e)
{
      if (e.Key == Key.Enter)
      {
           this.Focus();
      }
}
