推荐答案

你好b $ b

在回发后你将无法获得动态生成控件的值。

您可以使用客户端脚本（javascript）在隐藏字段中存储动态控件的值..

，你可以从后面的代码隐藏字段中访问这些值。

Hi
You wont be able to get the value of dynamic generated controls after postback.
You can store the values of the dynamic controls in Hidden field using Client Side scripting ( javascript )..
and you can access those values from hidden field in code behind.

好的你可以做一件事

ok you can do one thing on

if (!IsPostBack)
           {
               string tripid = "11850"; //Request.QueryString["tripid"].ToString();
               getStage();
               QuestionsPopulate("Booking");

           }

你已经在调用getStage（）;



现在把其他那里



和



将以下代码放入

You are already calling getStage();

now put else there

and

put following code in that

drpStage.DataBind();
