How to use partial views in asp net mvc

Introduction

ASP.NET is a popular programming language used for building web applications. One of the key of ASP.NET MVC is the ability to use views. Partial views you to break down your 's user into smaller, reusable components. In this article, we will explore how to use partial views in ASP.NET MVC with .

Creating a Partial View

To create a partial view in ASP.NET MVC, you need to follow a few simple steps. First, create a new view file with the .cshtml extension. This file will contain the HTML markup and syntax for your partial view. For example, let's create a partial view called “_ProductDetails.cshtml” that the details of a product:


@ Product

@Model.Name

@Model.Description

Price: $@Model.Price

In the above example, we have a partial view that takes a model of type “Product”. It displays the name, description, and price of the product using Razor syntax.

Using a Partial View

Once you have created a partial view, you can use it in your main views or other partial views. To use a partial view, you need to use the “Html.Partial” or “Html.RenderPartial” helper methods. Let's say we have a main view called “Index.cshtml” that displays a list of products. We can use the “_ProductDetails.cshtml” partial view to display the details of each product:


@model List

@foreach (var product in Model)
{
    
@Html.Partial("_ProductDetails", product)
}

In the above example, we are iterating over a list of products and using the “Html.Partial” method to render the “_ProductDetails.cshtml” partial view for each product.

Passing Data to a Partial View

Partial views can also accept additional data from the main view or controller. To pass data to a partial view, you can use the “ViewData” or “ViewBag” objects. For example, let's say we want to display a discount percentage for each product in the “_ProductDetails.cshtml” partial view:


@model Product

@{
    var discountPercentage = ViewData["DiscountPercentage"];
}

@Model.Name

@Model.Description

Price: $@Model.Price

Discount: @discountPercentage%

In the above example, we are retrieving the discount percentage from the “ViewData” object and displaying it in the partial view.

Conclusion

Partial views are a powerful feature in ASP.NET MVC that allow you to create reusable components for your web application's user interface. By breaking down your UI into smaller, modular pieces, you can improve code reusability and maintainability. In this article, we explored how to create and use partial views in ASP.NET MVC with examples. We also learned how to pass data to partial views using the “ViewData” or “ViewBag” objects. With this , you can now leverage the power of partial views in your ASP.NET MVC applications.
