I have a PartialView (_Letra) that receives information from a Controller named Music ... this way
public ActionResult CarregarLetra(string id, string artista, string musica)
{
return PartialView("_Letra", ArtMus(artista, musica));
}
public ResultLetra ArtMus(string artista, string musica)
{
//Conteúdo do metodo[..]
var queryResult = client.Execute<ResultLetra>(request).Data;
return queryResult;
}
Until then, no problem. What happens is that now I need to pass other information to this same PartialView (_Letra). This information is in PartialView (_Cifra).
So I added the following lines in my Music controller
public ActionResult CarregarCifra(string id, string artista, string musica)
{
return PartialView("_Cifra", GetCifra(artista, musica));
}
public ResultChords GetCifra(string artista, string musica)
{
var cfrTest= new Cifra();
var cifra = new ResultChords();
cifra.chords = cfrTest.GetInfs(artista, musica);
return cifra;
}
Everything working so far, PartialView _Cifra receives the information
I searched and found that I could use in PartialView _Letra the Html.Partial to load my PartialView _Cifra, I did this way then
I added
<div class="item">
<div class="text-carousel carousel-content">
<div>
@Html.Partial("_Cifra", new letero.mus.Infra.Models.ResultChords());
</div>
</div>
</div>
Now it starts to complicate why, the return of this is null, I believe it is due to a new instance of ResultChords that I make in Html.Partial
I have already tried using a ViewBag also to transpose the information between Partials, but probably not correctly, due to the return being null as well.
I've already done a lot of research and I'm not getting the information I need for PartialView _Letra.
There is a better way not to use Html.Partial, or to use it properly, as I am not aware.
In _Letra use
@Html.Action("CarregarCifra", "Music", new { id=Model.Id, artista=Model.Artista, musica=Model.Musica });
if the variables are available on the model then you can pass them in; otherwise, make use of the Viewbag and set them in CarregarLetra
Are you always passing a new object to the second partial? You could just create it at the top of the new _Cifra
partial.
_Cifra.cshtml
@{
var resultChords = new letero.mus.Infra.Models.ResultChords();
}
