如何把textbox 拆分成两个textbox

[gyg_123]

当点击一个按钮时，把原来的textbox拆成两个，里面的值也放到这两个里

[csdnFUCKINGSUCKS]

private void button1_Click(object sender, EventArgs e)
{
    textBox1.Width = textBox1.Width / 2;
    TextBox txtClone = new TextBox();
    txtClone.Text = textBox1.Text;
    txtClone.Width = textBox1.Width;
    txtClone.Location = new Point(textBox1.Location.X + textBox1.Width + 10, textBox1.Location.Y);
    Controls.Add(txtClone);
    Refresh();
}
