Question

Strange behavior! when I click on the button on the metro app all works well, but when i click enter(the button on the KB) the only thing that happens is everything is cleared!

This fails

private void TextBox_KeyDown_1(object sender, KeyRoutedEventArgs e)
    {
        if (e.Key == VirtualKey.Enter)
        {
            textBlock.Text = textBox1.Text;
           // textBox1.Text = "";
        }
    }

This works as expected

    private void Send_Click(object sender, RoutedEventArgs e)
    {

        textBlock.Text = textBox1.Text;
        textBox1.Text = "";
    }

What am I doing wrong ?

thanks

It would be best if when pressing Enter on the textbox, it will actualy simulate a click on the button, to assure that both actions are really the same.

private void TextBox_KeyDown_1(object sender, KeyRoutedEventArgs e)
{
    if (e.Key == VirtualKey.Enter)
    {
        this.Send.PerformClick();
    }
}

private void Send_Click(object sender, RoutedEventArgs e)
{
    textBlock.Text = textBox1.Text;
    textBox1.Text = "";
}

Also, as Chris mentioned, you shouldn’t really handle the KeyDown even in this case: you can set the AcceptButton property of the form to be the Send button, which means that when pressing Enter, the button will be pressed – even if not focused. This sort of problem is a good example of why using the AcceptButton property.
