新手在这里。但是在发布之前已经做了一些阅读和搜索。最近几天一直在摸不着头脑。
请注意，我正在尝试使用MVC（而不是Javascript）进行验证
我创建了自定义日期验证属性，并将该属性应用于模型中的相应字段。但是，我的观点并未反映自定义验证错误。但是，如果我应用默认属性，我的视图会反映基本验证错误（请参阅正则表达式）。
我试图实施使用， 1.自定义属性。 2.实现IValidateObject接口。
两者都不适用于日期对象。但是，调试代码时我注意到，当IsValid或Validate被命中时，将返回ValidationResult。
请注意，我使用过Ajax.BeginForm（不确定这是否会给我带来麻烦）。
