英文:
EditForm Validate with Multiple Classes
问题
我有一个包含多个类的剃刀EditForm页面，每个类都有自己的数据注释。当提交这个表单时，必须将数据插入不同的表格。当我点击提交时，没有触发任何验证。
<EditForm Model="@ViewModel.EditModel" OnSubmit="OnSubmit">
private void OnSubmit(EditContext context)
{
context.EnableDataAnnotationsValidation(); // 尝试强制执行验证
if (context.Validate()) // 总是为真
{
// 做一些操作
}
}
至于ViewModel，它有一个名为InformationSave的类，其中包含5个不同的类。
InformationSave EditModel { get; set; }
如果InformationSave.cs包含以下内容：
public TableA tablea { get; set; } = new TableA();
public TableB tablea { get; set; } = new TableB();
public TableC tablea { get; set; } = new TableC();
public TableD tablea { get; set; } = new TableD();
public TableE tablea { get; set; } = new TableE();
如果只有一个类（例如TableA）进行验证，那么验证会触发，但如果有多个类，则验证不会触发。
英文:
I have a razor EditForm page that it's model has several classes on it, each class has it's own data annotations. This form when submit must insert data to different tables. When I click the submit no validations are triggered.
<EditForm Model="@ViewModel.EditModel" OnSubmit="OnSubmit">
private void OnSubmit(EditContext context)
{
context.EnableDataAnnotationsValidation(); //Trying to force the validations
if(context.Validate()) //Always true
{
//Do stuff
}
}
As for the ViewModel it has a class named InformationSave that holds 5 different classes.
InformationSave EditModel { get; set; }
if the InformationSave.cs having
public TableA tablea { get; set; } = new TableA();
public TableB tablea { get; set; } = new TableB();
public TableC tablea { get; set; } = new TableC();
public TableD tablea { get; set; } = new TableD();
public TableE tablea { get; set; } = new TableE();
If I have a single class validation, for example, only TableA, then the validations do trigger, but not having multiple classes.

你需要添加 NuGet 包 Microsoft.AspNetCore.Components.DataAnnotations.Validation （请记住这是预发布版！）。然后在你的 Razor 文件中，不要使用 <DataAnnotationsValidator/>，而要使用 <ObjectGraphDataAnnotationsValidator/>。最后，你需要像这样修饰你的子类：
[ValidateComplexType]
public TableA tablea { get; set; } = new TableA();
[ValidateComplexType]
public TableB tablea { get; set; } = new TableB();
希望这对你有所帮助。

You need to add the nuget package
Microsoft.AspNetCore.Components.DataAnnotations.Validation
(it's prerelease, keep that in mind!)
Then in your razor file instead of <DataAnnotationsValidator/> you will use <ObjectGraphDataAnnotationsValidator/>.
Finally, you will decorate your child classes like this:
[ValidateComplexType]
public TableA tablea { get; set; } = new TableA();
[ValidateComplexType]
public TableB tablea { get; set; } = new TableB();
