ASP.NET MVC 3 _Layout.cshtml Controller

Question

Can anyone help me with the subject? I'm using Razor view engine and I need to pass some data to _Layout. How can I do it?

Answer 1

As usual you start by creating a view model representing the data:

public class MyViewModel
{
    public string SomeData { get; set; }
}

then a controller which will fetch the data from somewhere:

public class MyDataController: Controller
{
    public ActionResult Index()
    {
        var model = new MyViewModel
        {
            SomeData = "some data"
        };
        return PartialView(model);
    }
}

then a corresponding view (~/Views/MyData/Index.cshtml) to represent the data:

@{
    Layout = null;
}
<h2>@Model.SomeData</h2>

and finally inside your _Layout.cshtml include this data somewhere:

@Html.Action("index", "mydata")
