You Need to Do the Following, based on that Page:

<EditForm Model="@employee" EditContext="@editContextForButton">

And in the end of the form

<button onclick="@validSubmit">submitButton</button>

Finally you do the following in @code

private EditContext editContextForButton {get;set;}

protected override void OnTinitializedAsync(){
    editContextForButton  = new EditContext(YourModelHere);
}

private void validSubmit(){
    editContextForButton.Validate();
}

I Test it and it works!

You need to create validation attribute action filter for that and use it over your model/viewmodel. as shown in this example below:
