Use this:

C#

private void button1_Click(object sender, EventArgs e)
{
    string a;
    a = textBox1.Text;
    textBox2.Text += String.Format("{0}{1}", (String.IsNullOrEmpty(textBox2.Text)) ? "" : Enviroment.NewLine, a);
    textBox1.Clear();
}

This will put a newline in front of the appended text from textbox1, but only if textbox2 already had some non-empty text inside it.

Manfred

Solution 2

You can't, unless it is set as a multiline textbox (Set it's Multiline property to "true"). Then, it's just a case of adding a newline to the text:

C#

string a = textBox1.Text;
textBox2.Text += "\r\n" + a;
textBox1.Clear();

Or better:

C#

textBox2.Text = string.Format("{0}\r\n{1}", textBox2.Text, textBox1.Text);
textBox1.Clear();

Since it generates fewer intermediate strings.
