You can check whether or not the ModelState is valid, but keep in mind that you're only checking the validity of the ModelState at the time the web request was made:
您可以检查 ModelState 是否有效，但请记住，您只是在发出 Web 请求时检查 ModelState 的有效性：
@if (ViewData.ModelState.IsValid) {
...
}
Additionally, you can check validatity of a property on the model in the view:
此外，您可以在视图中检查模型上属性的有效性：
@if (ViewData.ModelState.IsValidField("FIELD_NAME")) {
...
}
