ASP.NET MVC – How to get current action from within a partial view

asp.net-mvcnet

I have a partial view that is rendered by several views which are returned by several action methods.

The partial view has a form that should post back to the called action method.

It is my understanding that if i just call

<% Html.BeginForm(); %>

from within a view, the form's action attribute will point to the called action method.
I can't do this, because I need to set the form's ID attribute for javascript purposes. The overload of Html.BeginForm that will let me set html attributes also requires an explicit controller and action. So, instead of using the Html helper, I could just write the form element out like:

<form action="<%=(NEED TO SOMEHOW GET THE URL TO THE CURRENT ACTION) %>" method="post" id="myForm">

I'm just not sure how to get the URL.

Just pass null for the controller and action. The correct values will be substituted. E.g.:

<% using (Html.BeginForm(null, null, FormMethod.Post, new { id = "employeeGroupForm" }))

Update for MVC 3

ViewContext.Controller.ValueProvider.GetValue("action").RawValue
ViewContext.Controller.ValueProvider.GetValue("controller").RawValue
ViewContext.Controller.ValueProvider.GetValue("id").RawValue

Update for MVC 4

ViewContext.Controller.RouteData.Values["action"]
ViewContext.Controller.RouteData.Values["controller"]
ViewContext.Controller.RouteData.Values["id"]

Update for MVC 4.5

ViewContext.RouteData.Values["action"]
ViewContext.RouteData.Values["controller"]
ViewContext.RouteData.Values["id"]

C# – How to create a dropdownlist from an enum in ASP.NET MVC

For MVC v5.1 use Html.EnumDropDownListFor

@Html.EnumDropDownListFor(
    x => x.YourEnumField,
    "Select My Type", 
    new { @class = "form-control" })

For MVC v5 use EnumHelper

@Html.DropDownList("MyType", 
   EnumHelper.GetSelectList(typeof(MyType)) , 
   "Select My Type", 
   new { @class = "form-control" })

For MVC 5 and lower

I rolled Rune's answer into an extension method:

namespace MyApp.Common
{
    public static class MyExtensions{
        public static SelectList ToSelectList<TEnum>(this TEnum enumObj)
            where TEnum : struct, IComparable, IFormattable, IConvertible
        {
            var values = from TEnum e in Enum.GetValues(typeof(TEnum))
                select new { Id = e, Name = e.ToString() };
            return new SelectList(values, "Id", "Name", enumObj);
        }
    }
}

This allows you to write:

ViewData["taskStatus"] = task.Status.ToSelectList();

by using MyApp.Common
