net动态控件按保存时取值问题
编辑功能： net 在后台动态添加控件，然后把给控件赋值，呈现到界面，然后修改控件的值，按保存。这个时候，得不到控件修改后的值，总是最开始赋值时候的值。这要怎么做呢？ 动态控件的id 可以得到，查看源文件时，id的值都是最初赋值时候的值。 为什么点保存的时候，得不到修改后的值呢？
TextBox txtXuhao { get; set; }
DropDownList dptea { get; set; }
TextBox txtBegin { get; set; }
TextBox txtEnd { get; set; }
TextBox txtCode { get; set; }
