Question

I have a partial view that shows a list of Categories. I’d like to put that partial view on any page, but I’d like to have it to call to the service and get a list of categories by itself without me having to do that in every controller action. Something like webforms in which you can put a code-behind on it.

For eg.

Actions

    public ActionResult Index()
    {
        JobListViewModel model = new JobListViewModel();
        model.Categories= jobService.GetCategories();

        return View(model);
    }

    public ActionResult Details(int id)
    {
        Job job = jobService.GetJob(id);
        return View(job);
    }

I created a partial that will take the model.Categories model and display a list. As you can see, the Index page will work fine, but I do not want to call it again in the Details page. Is there a way to make my partialview call to the GetCategories() service by itself?

Answer 1

Use Html.RenderAction – that gives the partial view its own controller action.
