Display a view from another controller in asp net mvc

Introduction

ASP.NET is a popular programming language used for building web applications. One requirement in ASP.NET MVC is to a view from controller. In this article, we will explore different to achieve this.

1: RedirectToAction

The RedirectToAction method is used to redirect the user to a different action method the same or a different controller. To display a view from another controller, we can redirect to the desired action method and let it render the view.


public class HomeController : Controller
{
    public IActionResult Index()
    {
        return RedirectToAction("About", "OtherController");
    }
}

public class OtherController : Controller
{
    public IActionResult About()
    {
        return View();
    }
}

In the above example, the Index action method in the HomeController redirects to the About action method in the OtherController. The About action method then renders the corresponding view.

Approach 2: Using PartialView

If you only need to display a partial view from another controller, you can use the PartialView method. This method allows you to render a partial view the user.


public class HomeController : Controller
{
    public IActionResult Index()
    {
        return PartialView("~/Views/OtherController/PartialView.cshtml");
    }
}

In the above example, the Index action method in the HomeController directly returns the PartialView method with the path to the desired partial view. The partial view is then rendered within the current view.

Approach 3: Using RenderAction

The RenderAction method is another way to display a view from another controller. This method allows you to render the of a specified action method within the current view.


public class HomeController : Controller
{
    public IActionResult Index()
    {
        return View();
    }

    public IActionResult RenderOtherAction()
    {
        return View("~/Views/OtherController/OtherAction.cshtml");
    }
}

In the above example, the Index action method in the HomeController renders the corresponding view. Within this view, we can use the RenderAction method to render the output of the RenderOtherAction action method in the OtherController.

Conclusion

Displaying a view from another controller in ASP.NET MVC can be achieved using different approaches. Whether you need to redirect to a different action method, render a partial view, or render the output of an action method within the current view, ASP.NET provides various methods to accomplish this task.
