asp.net-mvc – .input-validation-error为表单重新显示失败值时的文本框

我已经要求 question知道为什么在我的应用程序中,当我使用模型绑定来验证模型(TryUpdateModel())时,文本框被突出显示(即红色边框和粉红色阴影背景应用于文本框)但是当我使用时手动验证(ModelState.AddModelError).现在已经2天了,没有任何答案.我自己尝试过所有事情而没有成功.所以,我决定以不同的方式提出这个问题.

我理解IT的方式,这就是ModelBinding如何处理请求.

> ModelBinding从httpcontext获取传入值
>它实例化该模型的对象
>尝试将这些值解析为对象
>如果某个属性出现问题,它会使用ModelState.AddModelError标记出现错误的属性.
>重新显示视图

这是我的问题当重新显示表单时：

正在为其值无效突出显示的文本框做了什么？

我知道Site.css中的类很少,例如.input-validation-error和.field-validation-error应用于文本框.也许ModelBinding在内部使用一个命令,如AddCss(“#MyTextBox”,“.input-validation-error”).

如果我知道它是如何工作的,我可以(也许)手动解决我的问题.
