推荐答案

我以前通过存储在会话从控制数据做到了这一点。

I have done this before by storing the data from the controls in session.

每次动态添加控件，存储订立会话或视图状态例如控制当前的数据，然后在回发重新绑定。不是最优雅的解决方案，但它的工作。我把它这是一个web表单的问题？

Every time you dynamically add a control, store the current data entered into the controls in session or viewstate for example, and then rebind on postback. Not the most elegant solution but it worked. I take it this is a webforms question?

1. 添加动态控制点击


2. 保存当前表单数据


3. 在Page_Load中从视图状态的数据加载到控制
