Try this sample:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>







        AutoPostBack="true" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged">
            text1
            test2








in .cs:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.IO;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }

    protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
    {
        TextBox1.Visible = true;
        TextBox1.Text = DropDownList1.SelectedValue;
    }
}
