Cancel the Enter key on the Form:

I added in BeginForm: 

new { onkeydown = "return event.keyCode!=13",

The Complete Code: 

@using (Html.BeginForm("AdicionarAnexo", "Classe", FormMethod.Post, new { onkeydown = "return event.keyCode!=13", @encoding = "multipart/form-data", @enctype = "multipart/form-data", @id = "AnexoClasseForm", @class = "upload-form" }))
