Pass a string as parameter for a View in ASP.NET

Time:07-26

I'm having a hard time googling this, but I can't find my issue and I find it weird as it seems this should be something really simple (Maybe i'm using bad keywords)...

Anyway I have an ASP.NET Application And I would like to pass a string parameter to a cshtml view.

From My index.cshtml I pass the parameter I want:

<td>
    @Html.ActionLink("Crear saludo", "Create", new { nombreSeguidor = item })
</td>

This is the part where I'm lost... It receives the parameter correctly, but I'm unable to make use of the string on the Create.cshtml.

    // GET: Saludos/Create
    public ActionResult Create(string nombreSeguidor)
    {
        ViewBag.nombreSeguidor = nombreSeguidor; //This is my try on achieving the behaviour I want
        ViewBag.Seguidores_Id = new SelectList(_repositorioSeguidores.DameTodo(), "Id", "NombreTwitch");
        return View();
    }

It seems to receive Seguidores_Id correctly, but not my new parameter (The ViewBag.Seguidores_Id was create by Visual Automatically)

Thanks in advance

Edit:

Thxs for the reply:

It seems that the first answer was What I was looking for, but now I have other issues.

My intention on this view is to create an item with a model, but some of the variables will be created automatically. This is the model I have:

    public int Id { get; set; }
    public string Saludo { get; set; }
    public string CreadoPor { get; set; }
    public Nullable<int> Seguidores_Id { get; set; }

Id will be auto; CreadoPor will be an unique string if created this way (always the same); and Seguidores_Id will depend on the parameter "nombreSeguidor" We have passed.

So, in this view, the only variable I want to be editable is Saludo

How do I fill other variables? Until now, I was using this autogenerated-code:

@model string
@*@model TwitchWebApi.Models.Saludos*@

@{
    ViewBag.Title = "Create";
}

<h2>Create</h2>


@using (Html.BeginForm())
{
    @Html.AntiForgeryToken()

    <div >
        <h4>Saludos</h4>
        <hr />
        @Html.ValidationSummary(true, "", new { @class = "text-danger" })
        @*@Html.HiddenFor(model => model.Seguidores_Id)*@

        <p>
            Crear saludo para @Model
        </p>

        <div >
            @Html.LabelFor(model => model.Saludo, htmlAttributes: new { @class = "control-label col-md-2" })
            <div >
                @Html.EditorFor(model => model.Saludo, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.Saludo, "", new { @class = "text-danger" })
            </div>
        </div>

        <div >
            @Html.LabelFor(model => model.CreadoPor, htmlAttributes: new { @class = "control-label col-md-2" })
            <div >
                @Html.EditorFor(model => model.CreadoPor, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.CreadoPor, "", new { @class = "text-danger" })
            </div>
        </div>

        <div >
            @Html.LabelFor(model => model.Seguidores_Id, "Seguidores_Id", htmlAttributes: new { @class = "control-label col-md-2" })
            <div >
                @Html.DropDownList("Seguidores_Id", null, htmlAttributes: new { @class = "form-control" })
                @Html.ValidationMessageFor(model => model.Seguidores_Id, "", new { @class = "text-danger" })
            </div>
        </div>

CodePudding user response:

If you want to pass a string parameter from the public ActionResult Create(string nombreSeguidor) action method to the Create.cshtml view it is possible just make it like below:

// GET: Saludos/Create
public ActionResult Create(string nombreSeguidor)
{   
    ViewBag.Seguidores_Id = new SelectList(_repositorioSeguidores.DameTodo(), "Id", "NombreTwitch");
    return View((object)nombreSeguidor);
}

In the Create.cshtml:

@model string
<!DOCTYPE html>
<html>
<body>
    <div>
        The passed string: @Model
    </div>
</body>
</html>

Even preferable to use the strongly typed view instead of using ViewData or ViewBag.
