I made a if, in case something comes back, then he mounts a page, otherwise he should hide everything and show a message. It’s not an Alert, but a message on the same page. On my Lse I just hide a div and a form. That’s okay. I just don’t know how to generate a message, like a <h1>Mensagem</h1>, like that, not necessarily that, but something like that. Look at my else how are:

else
{
     $("#selecionarHotel").css("display","none");
     $("#filtroPesquisa").prop("hidden", true);
}

On Razor, you can do the following on your View:

@if (Model.Count > 0) {
    // Seu código
} else {
    <div>Não há registros a serem exibidos.</div>
}

For this to be viable you must have a Model applied to your view. For example:

@model IEnumerable<Caminho.Da.Minha.Classe>

  • I can’t get the Model Count. He doesn’t exist.

  • You can put in the question the complete code of your View?

  • the view is very large, but I can place the Model object that my view loads.

  • Could be just the header of View. I need to know how you send the information to View to edit my reply.

I imagine the data is coming in your View asynchronously. In this case, you can have a html ready to display that message and keep it in a class css that hides. Your case Model come empty, you can implement a routine javascript to display it, let’s take an example:

in his css

.no-data {
   display: none;
}

in your html, you could keep a div with your message applying the css that hides:

<div id="mensagem" class="no-data">Nenhuma registro encontrado.</div>

and to display, in your javascript:

$("#mensagem").show();

If the data in your View see directly into the Model, so you can implement this server-side routine to generate html, example:

@if (Model.Count > 0) 
{
    // sua exibição aqui...
} 
else 
{
    <div>Nenhuma registro encontrado.</div>
}
