Transferring data to a layout page

I have a page layoutwith variables to fill out. Example:

@ModelType KarateAqua.schoolModel

<html>
    <body>

        @RenderBody()

        <div id="footer">
            <div class="content">
                <div class="bottom_logo">
                    <a href="/"><span class="inv">@Model.schoolName</span></a>
                </div>
            </div>
        </div>
    </body>
</html>

I do not want to fill it in everyone ActionResult. Is there a way to transfer data to a page layoutonce and do it for all instances?

OK, since you want this to be set as soon as you can use the partial view. However, depending on your needs, you will need to have a few partial views (maybe not ideal if the sections are scattered across the _layout page)

your partial view will look like

@model KarateAqua.schoolModel

<div class="bottom_logo">
<a href="/"><span class="inv">@Model.schoolName</span>
</div>

controller

public class SchoolController : Controller
{
     public ActionResult Index()
     {
          //get schoolModel  
          return PartialView(schoolModel);
     }
}

_layout.cshtml , ,

@Html.Action("Index","School")

public class CurrentUserAttribute : ActionFilterAttribute
{
    public override void OnResultExecuting(ResultExecutingContext filterContext)
    {
        // Don't bother running this for child action or ajax requests
        if (!filterContext.IsChildAction && !filterContext.RequestContext.HttpContext.Request.IsAjaxRequest())
        {

            if (filterContext.HttpContext.Session != null)
            {
                var currentUser = filterContext.HttpContext.Session["CurrentUser"] as CurrentUser;
                if (currentUser != null)
                {
                    filterContext.Controller.ViewBag.CurrentUser = currentUser;
                }
            }
        }
    }

Your layout page:

@ViewBag.LayoutVar

Your HomeController:

public class HomeController : BaseController
{
   //Here some logic...
}

Your basecontroller

namespace ProjectName.Controllers
{
    public class BaseController : Controller
    {

        public YetkiController()
        {
            //This parameter is accessible from layout
            ViewBag.LayoutVar = "Suat";
        }
    }
}

The logic is simple: you create a BaseController that includes all the global parameters that you will use in the layout. (Like username or other data-based options)

You inherit (call) BaseControllerto get all the parameters in the current controller.
