生成控件后，无法调用前台JS方法。。无响应事件。。 --------------------编程问答-------------------- 把生成的html代码贴一下 --------------------编程问答-------------------- 你这是客户端的BUTTON不是服务器端的,肯定可以执行JS代码,再仔细找找哪里错了 --------------------编程问答-------------------- 问题找出来了，
是因为dr["TxtEn"].ToString().Replace("'",   "’")   读出来的时候在前台增加了"\n\r"导致前台页面换行。
谢谢上面2位了。。
