Query background
查询背景
I have a parent view and inside it there is a partial view. Partial view contains a form and submit button. The partial view has its own local view model and that view model is one of the properties of the Parent view model.
我有一个父视图，里面有一个部分视图。部分视图包含一个表单和提交按钮。局部视图有自己的局部视图模型，该视图模型是父视图模型的属性之一。
In case the validations on partial views fail, I want to, show the parent view as it is and highlight invalid fields in partial view.
如果部分视图的验证失败，我想要显示父视图，并突出部分视图中的无效字段。
The code is not breaking anywhere but when there is a validation error, somehow, i am not finding right way to show parent view with initialised model passed to it. And of course, to highlight the errors in partial view.
代码在任何地方都不会出错，但当出现验证错误时，不知何故，我无法找到正确的方式显示传递给它的初始化模型的父视图。当然，强调部分视图中的错误。
Any help would be appreciated. Thanks.

You need to show the parent view not the child one, so the action should look like:
您需要显示父视图而不是子视图，因此操作应该如下:
[HttpPost]
public ActionResult SubmitReview(ChildViewModel model)
{
var parentViewModel = write init code here;
parentViewModel.ChildModel = model;
if (ModelState.IsValid )
{
return View("Index", parentViewModel );
}
ModelState.AddModelError("", "Some Error.");
return View("Index", parentViewModel );
}
