Html.Actionlink Method

HTML.ActionLink method

I think what you want is this:

ASP.NET MVC1

Html.ActionLink(article.Title, 
                "Login",  // <-- Controller Name.
                "Item",   // <-- ActionMethod
                new { id = article.ArticleID }, // <-- Route arguments.
                null  // <-- htmlArguments .. which are none. You need this value
                      //     otherwise you call the WRONG method ...
                      //     (refer to comments, below).
                )

This uses the following method ActionLink signature:

public static string ActionLink(this HtmlHelper htmlHelper, 
                                string linkText,
                                string controllerName,
                                string actionName,
                                object values, 
                                object htmlAttributes)

ASP.NET MVC2

two arguments have been switched around

Html.ActionLink(article.Title, 
                "Item",   // <-- ActionMethod
                "Login",  // <-- Controller Name.
                new { id = article.ArticleID }, // <-- Route arguments.
                null  // <-- htmlArguments .. which are none. You need this value
                      //     otherwise you call the WRONG method ...
                      //     (refer to comments, below).
                )

This uses the following method ActionLink signature:

public static string ActionLink(this HtmlHelper htmlHelper, 
                                string linkText,
                                string actionName,
                                string controllerName,
                                object values, 
                                object htmlAttributes)

ASP.NET MVC3+

arguments are in the same order as MVC2, however the id value is no longer required:

Html.ActionLink(article.Title, 
                "Item",   // <-- ActionMethod
                "Login",  // <-- Controller Name.
                new { article.ArticleID }, // <-- Route arguments.
                null  // <-- htmlArguments .. which are none. You need this value
                      //     otherwise you call the WRONG method ...
                      //     (refer to comments, below).
                )

This avoids hard-coding any routing logic into the link.

 <a href="/Item/Login/5">Title</a> 

This will give you the following html output, assuming:

1. article.Title = "Title"
2. article.ArticleID = 5
3. you still have the following route defined

.
.

routes.MapRoute(
    "Default",     // Route name
    "{controller}/{action}/{id}",                           // URL with parameters
    new { controller = "Home", action = "Index", id = "" }  // Parameter defaults
);

How to correctly use Html.ActionLink with ASP.NET MVC 4 Areas

I hate answering my own question, but @Matt Bodily put me on the right track.

The @Html.Action method actually invokes a controller and renders the view, so that wouldn't work to create a snippet of HTML in my case, as this was causing a recursive function call resulting in a StackOverflowException. The @Url.Action(action, controller, { area = "abc" }) does indeed return the URL, but I finally discovered an overload of Html.ActionLink that provided a better solution for my case:

@Html.ActionLink("Admin", "Index", "Home", new { area = "Admin" }, null)

Note: , null is significant in this case, to match the right signature.

Documentation: @Html.ActionLink (LinkExtensions.ActionLink)

Documentation for this particular overload:

LinkExtensions.ActionLink(Controller, Action, Text, RouteArgs, HtmlAttributes)

It's been difficult to find documentation for these helpers. I tend to search for "Html.ActionLink" when I probably should have searched for "LinkExtensions.ActionLink", if that helps anyone in the future.

Still marking Matt's response as the answer.

Edit: Found yet another HTML helper to solve this:

@Html.RouteLink("Admin", new { action = "Index", controller = "Home", area = "Admin" })

C# MVC 5 Html.ActionLInk

I think the proper URI should be (/Customer/CustomerView/2) and not (/CustomerController/CustomerView/2).

below is correct line of code.

@Html.ActionLink(customer.Name, "CustomerView", "Customer", new { id = customer.Id }, null)

How do I make an MVC ActionLink call a POST method?

When creating a link to a controller action in ASP.NET MVC, using the generic ActionLink method is preferable, because it allows for strongly typed links that are refactoring friendly.

Default: ActionLink

@Html.ActionLink("Delete", "Delete", new { id = item.ID })

Using Button:

<input type="button" title="Delete" value="D" onclick="location.href='@Url.Action("Delete", "movies", new { id = item.ID })'" />

Using Image:

<a href="@Url.Action("Delete", "movies", new { id = item.ID })" title="Edit">
<img src="../../Content/Images/Delete.png" />
</a>

ASP.Net MVC5 Html.ActionLink to index method in different controller

I believe your call is matching the wrong overload of the helper method.

As written, it will match this signature:

public static MvcHtmlString ActionLink(this HtmlHelper htmlHelper, string linkText, string actionName, object routeValues, object htmlAttributes)

Notice there is no controller in there.

Try this instead:

@Html.ActionLink("View Staff", "Index", "Staff" , new { id =  item.UnitCode }, null)

Which should match the right signature with controller:

public static MvcHtmlString ActionLink(this HtmlHelper htmlHelper, string linkText, string actionName, string controllerName, object routeValues, object htmlAttributes)

Html.ActionLink extension

The function you are looking for is:

HtmlHelper.AnonymousObjectToHtmlAttributes()

https://msdn.microsoft.com/en-us/library/system.web.mvc.htmlhelper.anonymousobjecttohtmlattributes(v=vs.118).aspx

Here is one version of the ModalLink Extension:

public static MvcHtmlString ModalLink(this HtmlHelper htmlHelper, string title, string linkText, string actionName, string controllerName, object routeValues, object htmlAttributes)
{
  // Add 'show-in-modal' class here
  // Add 'data-title' attribute here

  var htmlAttr = HtmlHelper.AnonymousObjectToHtmlAttributes(htmlAttributes);

  const string classKey = "class";
  const string titleKey = "data-title";

  const string classToAdd = "show-in-modal";
  if (htmlAttr.ContainsKey(classKey) == true)
  {
    htmlAttr[classKey] += " " + classToAdd;
  }
  else
  {
    htmlAttr.Add(classKey, classToAdd);
  }

  if (htmlAttr.ContainsKey(titleKey) == true)
  {
    htmlAttr[titleKey] = title;
  }
  else
  {
    htmlAttr.Add(titleKey, title);
  }

  return htmlHelper.ActionLink(linkText, actionName, controllerName, new RouteValueDictionary(routeValues), htmlAttr);
}

Html.ActionLink onclick method equivalent for Url.Action

Try this...

<a href="@Url.Action("Action","Controller", new {refNumber = item.RefNumber, null})" onclick="return confirm('are you sure?');">Delete</a>

As mentioned in the comments, I'd highly recommend changing your action to a POST. Can read more about that here.

ASP.NET MVC : Actionlink does not navigate to correct action method of same name but different parameters

An ActionLink is rendered as an <a href="...."> HTML element and therefore is always a GET request and thus always goes to the action method decorated with [HttpGet] annotation - it does NOT look at any parameter list or anything like that.

If you want to call the POST action method, you need to have a HTML form and a submit button on that form - that will be a POST request to be handled by the method decorated with the [HttpPost] annotation ...

ActionLink with parameter in another controller MVC5

There is another overload of ActionLink helper which lets you specify the controller name, action name and the route values.

public static MvcHtmlString ActionLink(
    this HtmlHelper htmlHelper,
    string linkText,
    string actionName,
    string controllerName,
    object routeValues,
    object htmlAttributes
)

So if you want to render a which points to Table2/Action1, you ca use that overload

@Html.ActionLink("Edit", "Action1","Table2", new { ParentID = 100 },null)

You can change hardcoded 100 with your actual value.

Using ASP.Net MVC Razor - @Html.ActionLink

You are specifying the controller and action both in the same parameter using the overload which takes just action method name which is not correct in this case as you want to call action method on a different controller class.

You actually need to specify action method name and controller name using the following overload method:

@Html.ActionLink("Order", "ProductList","Products", 
                 new { id = Model.ID }, 
                 new { @class = "link-button btn-primary" })

and in controller class you will have to add an action method for it:

public class ProductsController : Controller
{

     ................
     ................
     // other action methods here

     public ActionResult ProductsList(int id)
     {
        // your code goes here and finaly returns view
        // var model = new Model();
        return View(model)
     }

}
