Difference between Html.Action() and Html.RenderAction() in ASP.NET MVC.
HTML.Action and
HTML.RenderAction are two important methods in ASP.NET MVC that allow developers to render a partial view within a main view. These methods are often used to create reusable code blocks that can be easily maintained and updated. In this blog post, we will explore the differences between
HTML.Action and
HTML.RenderAction and the benefits of using each method.
HTML.Action
For detailed tutorial about
Html.Action check this.
HTML.Action is used to render a partial view as an HTML string, which can then be passed to the main view as a model property. The
HTML.Action method returns the partial view as a string, which can be used to render the content in the main view. This method can be used to dynamically render content based on a specific condition.
Example:
public ActionResult GetPartialView()
{
return PartialView("_PartialView");
}
In the main view, the partial view can be rendered using the following code:
@{
var partialView = Html.Action("GetPartialView", "Home");
}
@partialView.ToHtmlString()
HTML.RenderAction

HTML.RenderAction, on the other hand, is used to directly render a partial view within the main view. The
HTML.RenderAction method does not return the partial view as a string, but instead, directly renders the content to the main view. This method is ideal for rendering content that needs to be displayed immediately and is not dependent on any specific condition.
Example:
@Html.RenderAction("GetPartialView", "Home")
Differences between
HTML.Action and
HTML.RenderAction
The main difference between
HTML.Action and
HTML.RenderAction is the way the partial view is rendered.
HTML.Action returns the partial view as a string, while
HTML.RenderAction directly renders the content to the main view. This means that
HTML.Action is ideal for rendering content dynamically based on a specific condition, while
HTML.RenderAction is ideal for rendering content immediately.
Benefits of using
HTML.Action and
HTML.RenderAction
- Reusable Code: By using
HTML.Action and HTML.RenderAction, developers can create reusable code blocks that can be easily maintained and updated.
- Better Code Organization: The partial views can be organized in a separate folder, making it easier to manage and maintain the code.
- Increased Performance:
HTML.RenderAction is faster than HTML.Action because it directly renders the content to the main view, avoiding the overhead of returning the partial view as a string.
In conclusion,
HTML.Action and
HTML.RenderAction are two useful methods in ASP.NET MVC that allow developers to render a partial view within a main view. Each method has its own benefits and can be used based on the specific requirements of a project. Understanding the differences between these methods and the benefits of using each one is essential for developing efficient and maintainable ASP.NET MVC applications.
