Asp net core multiple partial views in one page passing models and calling act

ASP.NET is a popular used for developing web applications. It provides a powerful framework for building and websites. One common requirement in web development is the need to display multiple partial on a single page, passing models and calling actions. In this article, we will explore how to achieve this using ASP.NET Core.

To begin, let's take a look at the basic structure of an ASP.NET Core application. The code snippet below shows the starting point of an ASP.NET Core application:


using Microsoft..Mvc;
using System.Collections.Generic;

namespace MyApp.Controllers
{
    public class HomeController : Controller
    {
        public IActionResult Index()
        {
             View();
        }
    }
}

In this example, we have a HomeController with an Index action that returns a view. This is the entry point of our application.

Now, let's say we want to display multiple partial views on the Index page, each with its own model and the ability to call actions. To achieve this, we can make use of the PartialView method provided by the Controller class.

First, let's a partial view called “_PartialView1.” and its model:


@model MyApp.Models.PartialView1Model

Partial View 1

This is the first partial view.

Model data: @Model.Data

In this example, we have a simple partial view that displays some text and the data from the model. It also includes a button that calls the “Action1” action in the “HomeController”.

Next, let's create another partial view called “_PartialView2.cshtml” with a different model:


@model MyApp.Models.PartialView2Model

Partial View 2

This is the second partial view.

Model data: @Model.Data

Similarly, this partial view displays some text and the data from its model. It also includes a button that calls the “Action2” action in the “HomeController”.

Now, let's modify the Index action in the HomeController to pass the models to the partial views:


public IActionResult Index()
{
    var model1 = new PartialView1Model { Data = "Model 1" };
    var model2 = new PartialView2Model { Data = "Model 2" };

    ViewBag.PartialView1Model = model1;
    ViewBag.PartialView2Model = model2;

    return View();
}

In this example, we create instances of the PartialView1Model and PartialView2Model classes and assign them to ViewBag properties. These models will be accessible in the partial views.

Finally, let's modify the Index view to render the partial views:


@{
    var model1 = ViewBag.PartialView1Model as MyApp.Models.PartialView1Model;
    var model2 = ViewBag.PartialView2Model as MyApp.Models.PartialView2Model;
}

Index Page

@Html.Partial("_PartialView1", model1) @Html.Partial("_PartialView2", model2)

In this example, we retrieve the models from the ViewBag and pass them to the Html.Partial method, which renders the corresponding partial views.

By following these steps, we have successfully displayed multiple partial views on a single page, passing models and calling actions. Each partial view has its own model and can interact with the server-side code.

In conclusion, ASP.NET Core provides a flexible and efficient way to display multiple partial views on a single page. By utilizing the PartialView method and passing models, developers can create dynamic and interactive web applications.
