ASP.Net MVC – Conditional rendering Partial Views with Action<T> delegate

This is an update to my previous post regarding conditional rendering partial views, in that I used the internal implementation of the Html.RenderPartail(…) method to create the Html extension. Later I found a simple way to achieve the same using Action<T> delegate

<p>Partial rendering with Action Methods</p>        
<% Html.PartialIf(this.Model.Exists, html => html.RenderPartial("MyPartialView")); %>

If you look at the “PartialIf” implementation, it is simple, cleaner than the previous technique I have mentioned in my post.

public static void PartialIf(this HtmlHelper htmlHelper, bool condition, Action<HtmlHelper> action)
    if (condition)

That’s it :)
