A partial view in ASP.NET MVC is a reusable portion of a web page. It is a .cshtml or .vbhtml file that contains HTML code. It can be used in one or more Views or Layout Views. You can use the same partial view at multiple places and eliminates the redundant code.

Here are some of the benefits of using partial views in ASP.NET MVC:

  • Reusability: Partial views can be reused in multiple views, which can help to reduce code duplication and improve code readability.
  • Maintainability: Partial views can be easily updated or modified, without affecting the rest of the application.
  • Performance: Partial views can be cached, which can improve the performance of the application.

To create a partial view, you can use the following steps:

  1. Right-click on the Views folder in the Solution Explorer.
  2. Select "Add" > "View".
  3. In the "Add View" dialog box, select the "Create a partial view" checkbox.
  4. Enter a name for the partial view.
  5. Click "Add".

The partial view will be created in the Views folder. You can then add HTML code to the partial view.

To use a partial view in a view, you can use the following syntax:

Code snippet

@Html.Partial("~/Views/Shared/_MyPartialView.cshtml")

The @Html.Partial() helper method will render the partial view in the current view.

Here is an example of how to use a partial view to render a list of items:

Code snippet

@model IEnumerable<MyViewModel>

<ul>
@foreach (var item in Model)
{
    <li>@item.Name</li>
}
</ul>

The @model directive tells ASP.NET MVC that the view model for this view is an instance of the MyViewModel class. The foreach loop iterates through the list of items and renders a list item for each item. The @Html.Partial() helper method is used to render the partial view that contains the markup for the list item.

Partial views can be a valuable tool for improving the maintainability, performance, and reusability of ASP.NET MVC applications.

The partial-view is a reusable view (like a user control) which can be embedded inside other views. As example let’s say all your pages of your site have a standard structure with left menu, header, and footer as shown in the image below.
