你需要使用 ViewState 时要小心，以避免页面性能问题。此外 ViewState 在大小方面有限制，因此请确保不要在其中存储大量数据。



如前所述，您可以使用JavaScript / jQuery在客户端添加动态控件。这样，所有交互只发生在浏览器上，因此您可以快速响应。只需谷歌使用jquery添加动态文本框来获取更多示例。这是我发现的一个：如何使用jQuery动态添加/删除文本框 [ ^ ]

You need to be careful when using ViewState to avoid page performance issue. Also ViewState has a limit when it comes to size, so make sure that you don't store a huge amount of data in it.

As already suggested, you can use JavaScript/jQuery to add dynamic controls at the client. That way all interactions only happens at the browser, so you can have a fast response. Just google "adding dynamic textbox using jquery" to get more examples. Here's one I found: How to add / remove textbox dynamically with jQuery[^]
