C#动态增加控件并且设置dockstyle.left以后，每次都是在第一个位置增加了控件，有办法从左往右加吗？

  private void dgvAddress_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
    {
        DataGridViewRow dgv = dgvAddress.CurrentRow;
        DataRowView drv = (DataRowView)dgv.DataBoundItem;
        DataRow dr = drv.Row;

        Model.MessageInfo oTempInfo = new Model.MessageInfo(dr);

        TextBox txt_recipient = new TextBox();
        txt_recipient.Multiline = false;
        txt_recipient.BorderStyle = BorderStyle.None;
        txt_recipient.ReadOnly = true;
        txt_recipient.Text = oTempInfo.Recipient + ";";
        Graphics g = Graphics.FromHwnd(txt_recipient.Handle);
        SizeF size = g.MeasureString(txt_recipient.Text, txt_recipient.Font);
        txt_recipient.Width = (int)size.Width;

        panel3.Controls.Add(txt_recipient);

        txt_recipient.Dock = DockStyle.Left;
    }

问题是每次双击都是在最左面加一个，我想从左往右按顺序加，请教各位。

DockStyle.Left后放入的控件优先级高，看看能不能改下放入的顺序，比如说每次添加控件时先保存一下旧的控件，清空之后，再按顺序放入新的控件和旧的控件
