Hi John,

If you need just one character on "Enter" then you can just handle PreviewKeyDown event on TextBox and paste following handler:

    private void Txt_OnPreviewKeyDown(object sender, KeyEventArgs e)


        if (e.Key == Key.Enter)


            var txtBox = e.Source as TextBox;

            var selectionStart = txtBox.SelectionStart;

            txtBox.Text = txtBox.Text.Insert(selectionStart, "\n");

            txtBox.Select(selectionStart + 1, 0);

            e.Handled = true;
