I have found solutions (but I don't understand why ...) 我已经找到了解决方案（但是我不明白为什么...）
I must transform FORM action="demo_simpleform.aspx" method="post" into FORM runat="server". 我必须将FORM action =“ demo_simpleform.aspx” method =“ post”转换为FORM runat =“ server”。 Ok, I understand that MUST insert runat="server" parameter (in form declaration and in all objects inside my form) but why I nedd to remove action="demo_simpleform.aspx" method="post" ? 好的，我知道必须插入runat =“ server”参数（在表单声明中以及表单中的所有对象中），但是为什么我想删除action =“ demo_simpleform.aspx” method =“ post”？
