I am having a problem with validation of a editform in blazor.
My form is as follows.

<EditForm Model="@FormModel" OnValidSubmit="@HandleValidSubmit" OnInvalidSubmit="@HandleInValidSubmit">
 <DataAnnotationsValidator />
    <div>
        <InputText class="form-control" id="firstName" type="text" placeholder="First Name" @bind-Value="@FormModel.FirstName" />
        <label for="firstName">First Name</label>
        <ValidationMessage For="@(() => FormModel.FirstName)" />
    </div>            
</EditForm>

If i submit the form from one that started out empty, the validation works fine.
In my .cs file i have…

FormModel = new FormUIModel();

The FormUIModel has a required parameter

[Required(ErrorMessage = "First Name Required")]
public string? FirstName { get; set; }

this works fine. But if I try and do it as an update, it does not Validate. It goes directly to the OnValidSubmit.

the only difference is that after I new up the FormModel, I then populate it as so..

FormModel = new FormUIModel();
FormModel = await _service.GetFormData(rowId)

Even if I delete the data in the firstname field, it will not show the ‘Required” message and never goes to the HandleInvalidSubmit.

Help is appreciated
