ASP.Net 4.0 HtmlGenericControl does not support the "Type" attribute as defined in your code, the error explains that, Parser Error Message: 'email' is not a valid type for an input tag., this is a arguably a "well known" or easily discovered bug in the ASP.Net framework.

我个人的preference最终被转移到 ASP.Net MVC 3 ，其相当陡峭的学习曲线和一个大的变化从ASP.Net Web开发的Web窗体的风格但它很快就忘记了，一旦你习惯了symantics和编码风格。

My personal preference ended up being to move to ASP.Net MVC 3, its quite a steep learning curve and a big change from the "Web Forms" style of ASP.Net web development however its soon forgotten once you get used to the symantics and coding styles.
