我对这个问题深感不安,希望各种帮助!我必须创建一个页面,用户可以通过单击按钮添加更多行。例如,我有第一行有两个文本框(名称和出生日期),第二行带有“添加行”按钮。当用户点击“添加行”按钮时,第一行应该被克隆和重复...但用户不能添加超过5行。后来所有的信息都需要保存在SQL表中。在C#中如何实现这一点?只需点击一下按钮即可添加文本框行
我附加我的示例ASP.NET。谁能帮帮我吗?
PS:我已阅读并尝试过“如何:将行和单元格动态添加到表Web服务器控件”......但这不适用于我。

@Pranay是的,我一定会做到这一点。顺便说一句,喜欢你使用GridView控件的想法,我会尝试一下。 – AlwaysANovice
谢谢大家的帮助!然而,我仍然坚持我将不得不从行中收集所有信息并将它们保存到SQL表的任何部分,任何人都可以请帮助我吗? – AlwaysANovice
