Preloader Asp.net MVC

Question

How can I do a preloader(carrying...) while it is rendering the view on @RenderBody ?

In search only found examples using Partial, but Views not

Any idea?

Answer 1

It’s not much of a secret:

Controller

public JsonResult MinhaAction(int id)
{
    // Preenchimento de 'meuJson', e tal
    return Json(meuJson);
}

View

I’m using jQuery, and supposing you’ve already found a "loading" screen somewhere. I’m going to assume that it sits inside a <div> whose id is "loading":

$('#meuLink').click(function()
{
    var action = '@Html.ResolveUrl("~/MeuController/MinhaAction/")' + $('#campoId').val();
    $('#carregando').show()
    $.getJSON(action, null, function(variavelDeCallback) 
    {
        // Faça aqui o que precisa com 'meuJson'
        $('#carregando').hide()
    });
});
