Instead of @Html.RenderAction() Use @{Html.RenderAction();}
Here is a possible reusable implementation in c# : class DisposableHelper : IDisposable { private Action end; // When the object is created, write “begin” function public DisposableHelper(Action begin, Action end) { this.end = end; begin(); } // When the object is disposed (end of using block), write “end” function public void Dispose() { end(); … Read more

Ex: @Html.TextBoxFor(model => model.propertyName, new {@class = “disabledClass” })
There is no caching involved here. It’s just how HTML helper work. They first look at the ModelState when binding their values and then in the model. So if you intend to modify any of the POSTed values inside your controller action make sure you remove them from the model state first: [HttpPost] public virtual … Read more
You could construct a drop down list: @{ // you can put the following in a back-end method and pass through ViewBag var selectList = Enum.GetValues(typeof(UserStatus)) .Cast<UserStatus>() .Where(e => e != UserStatus.Pending) .Select(e => new SelectListItem { Value = ((int)e).ToString(), Text = e.ToString() }); } @Html.DropDownListFor(m => m.Status, selectList)

There is no longer need for MvcHtmlString (which added on top of HtmlString for compatibility reasons) so you can simply use Microsoft.AspNet.Mvc.Rendering.HtmlString.

Update (for ASP.NET Core 3.1): You need to use Microsoft.AspNetCore.Html.HtmlString … Read more
