MVC C# Return RenderPartial in C#

The RenderPartial method in MVC is used to render a specified partial view as a string in the current view. It is a useful technique when you want to include reusable components or display partial data within a view.

Usage

The RenderPartial method can be used in the following way:

@{
    // Renders the "_PartialViewName" partial view and returns it as a string
    var partialViewAsString = Html.Partial("_PartialViewName").ToString();
    
    // Output the partial view as HTML
    @Html.Raw(partialViewAsString)
}

Here, Html.Partial method is called with the name of the partial view as a parameter. The method then returns the rendered partial view as a string using the ToString method. Finally, the result is outputted using @Html.Raw to prevent HTML encoding.

Note: The _PartialViewName should be replaced with the actual name of the partial view you want to render.

Example

Let's consider an example where you have a partial view named _UserDetails.cshtml that displays user details. You want to render this partial view within a main view named Index.cshtml.

_UserDetails.cshtml (Partial View)
@model User // Assuming User is a model class

<div>
    <h3>User Details</h3>
    <p>Name: @Model.Name</p>
    <p>Email: @Model.Email</p>
</div>
Index.cshtml (Main View)
@{
    var userDetails = Html.Partial("_UserDetails", new User { Name = "John Doe", Email = "johndoe@example.com" }).ToString();
}

<!DOCTYPE html>
<html>
<head>
    <title>Index</title>
</head>
<body>
    <!-- Render the partial view within the main view -->
    @Html.Raw(userDetails)
</body>
</html>

In this example, the _UserDetails partial view is rendered within the Index main view using the RenderPartial method. The Html.Partial method is called with the partial view name and the User model object to populate the necessary data. The rendered result is then outputted as HTML using @Html.Raw.

Note: The User model should be replaced with your actual model class.

Conclusion

Using the RenderPartial method in MVC C# allows you to include reusable components or display partial data within your views. By returning the rendered partial view as a string, you can easily manipulate and output it as needed within your application.
