本文展示了如何在ASP.NET中使用Repeater控件动态显示和处理TextBox输入值。通过示例代码解释了在Page_Load事件中如何从Session中获取并设置TextBox的值，以及在按钮点击事件中如何收集并保存TextBox的数据到Session。

1、自己做了一个demo，属性对应属性值，属性不是写死的后台可以维护，值是用户自己填写的，方便以后查看

.aspx文件中

.cs文件中

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            BindDate();
            HyperLink1.Visible = false;

            if (Request.QueryString["id"] == "1"&&HttpContext.Current.Session["info"]!=null)
            {
                btnAdd.Text = "保存";
                List<Test> list = new List<Test>();
                string sName = HttpContext.Current.Session["info"] as string;
                string[] ss = sName.Split(',');
                foreach (RepeaterItem item in rpShuxing.Items)
                {
                    TextBox txtName = (TextBox)item.FindControl("txtShuxing");
                    Label lbName = (Label)item.FindControl("lbName");
                    foreach (var item1 in ss)
                    {
                        string[] nnnn = item1.Split(':');
                        if (nnnn.Length == 2 && lbName.Text == nnnn[0])
                        {
                            txtName.Text = nnnn[1];
                        }
                    }
                }
            }
        }
    }

    private void BindDate()
    {
        List<Test> list = new List<Test>();
        Test t = new Test();
        t.SName = "种类";
        list.Add(t);
        Test t1 = new Test();
        t1.SName = "产地";
        list.Add(t1);
        Test t2 = new Test();
        t2.SName = "口味";
        list.Add(t2);
        Test t3 = new Test();
        t3.SName = "颜色";
        list.Add(t3);
        rpShuxing.DataSource = list;
        rpShuxing.DataBind();
    }
    protected void btnAdd_Click(object sender, EventArgs e)
    {
        StringBuilder sName = new StringBuilder();
        foreach (RepeaterItem item in rpShuxing.Items)
        {
            TextBox txtName = (TextBox)item.FindControl("txtShuxing");
            Label lbName = (Label)item.FindControl("lbName");
            if (txtName.Text != "")
            {
                sName.Append(lbName.Text + ":" + txtName.Text + ",");
            }
        }
        lbList.Text = sName.ToString().TrimEnd(',');
        HyperLink1.Visible = true;
        HttpContext.Current.Session["info"] = sName.ToString().TrimEnd(',');
    }

    public class Test
    {
        private string m_sName;

        public string SName
        {
            get { return m_sName; }
            set { m_sName = value; }
        }

        private string m_sValue;

        public string SValue
        {
            get { return m_sValue; }
            set { m_sValue = value; }
        }

        private string m_sInfo;
