请教高手！！在Panel动态创建的控件 无法读取创建控件中的值。

在Panel中动态创建的控件 但是读取Panel中的Controls=1  创建的时候又不是正确的。代码如下：namespace SHYX.WebUI.Bussiness
{
    public partial class DBCEdt : SHYX.WebUI.PageBase
    {        protected void Page_Load(object sender, EventArgs e)
        {
            CheckRight(Constants.BUSINESSUNIT_GGSQSHList_MODULEID);
            string opt = Request.Params.Get("Opt");
            Session["DBCList:Opt"] = opt;
            this.tbYwlx.Text = "分析调查";
            Session["DBCEdt:ZBID"] = Request.Params.Get("ZBID");
            string ZMDBM = Request.Params.Get("ZMDBM");
           
            if (!Page.IsPostBack)
            {
                if (opt != null)
                    Opt = opt;
                if (Opt == "0")
                {
                 this.tbZT.Text = "";
                   
                }
                else
                {
                    SetCtrols(true);
                    this.tbZT.Text = "新调查";
                }
                if (Opt != "1")
                {

  1.   

    动态创建的控件在刷新之后就从页面消失了
    你应该在Page_Load()中再重新添加一次才可以的
      

  2.   

    protected void Page_Load(object sender, EventArgs e)
      {
      CheckRight(Constants.BUSINESSUNIT_GGSQSHList_MODULEID);
      string opt = Request.Params.Get("Opt");
      Session["DBCList:Opt"] = opt;
      this.tbYwlx.Text = "分析调查";
      Session["DBCEdt:ZBID"] = Request.Params.Get("ZBID");
      string ZMDBM = Request.Params.Get("ZMDBM");
        
      if (!Page.IsPostBack)
      {
        XSDCMQ(ZBID);//生成控件
      }
     
        
      }还是放在if (!Page.IsPostBack)
    { 
    }
    XSDCMQ(ZBID);//生成控件
