    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }
        protected void Button1_Click(object sender, EventArgs e)
        {
            Response.Write(TextBox1.Text);
        }
        public string Text
        {
            get
            {
                return TextBox1.Text;
            }
            set
            {
                TextBox1.Text = value;
            }
