使用InputBindings时如何避免多行TextBox Enter键被吞咽？

Question

I'm doing WPF MVVM and have the following XAML code:

<TextBox Grid.Row="1" Name="Console" MinWidth="500" HorizontalAlignment="Stretch" AcceptsReturn="True" CharacterCasing="Upper" TextWrapping="WrapWithOverflow" Cursor="IBeam">
  <TextBox.InputBindings>
    <KeyBinding Command="{Binding Path=MyCommand}" CommandParameter="{Binding Text, ElementName=Console}" Key="Enter"/>
  </TextBox.InputBindings>
</TextBox>

When handling the Enter press in the ViewModel's command property (initialized in constructor with event handler added):

private readonly MyCommand myCommand;
public ICommand MyCommand
{
  get
  {
    return myCommand;
  }
}

private void OnCommand(object sender, MyCommandEventArgs e)
{
  <do something>
}

The event handler is called allright, but the Enter keypress is never passed back to the TextBox and the newline is not added (the cursor stays on the same line).

Doesn't event bubbling ensure that the Enter keypress gets passed on to the TextBox?

Answer 1

Could you just add "\\n" to your textbox' Text-value?

(Would have add that as a comment but I may not do that yet...)
