How I can use in asp.net multiple controllers?

Question

I have following two controllers: HomeController and DocGenController. The HomeController is the default controller in my project. I would like to open with a button-click a function in my DocGenController. For example: I created on my page a top-navigation. I used this code to open the DocGen.cshtml- page (via the controller HomeController): @Html.ActionLink("Generator", "DocGen", "Home").

Ok, now I tried this: @Html.ActionLink("Add Value", "AddValue", "DocGen", new { @class = "btn btn-primary" }) but I get every time this Error: The resource (/Home/AddValue) can be not found (Error: 404) .

Why he try to open /Home/AddValue ?!

How can I use my DocGenController?

Thanks for your help

@Html.ActionLink("Add Value", "Home", "DocGen", new { @class = "btn btn-primary" },new {param1=1,param2=2}) action link has many overloads, the one you are using , actionlink('title','controller','action',new{other parameters etc}) — Arun Prasad E S

As per your code @Html.ActionLink("Generator", "DocGen", "Home") Home is the controller and DocGen is action. Please swap them and try. — Rahul Jain

Sorry, I meant to use as : @Html.ActionLink("Generator", "YOUR FUNCTION NAME", "DocGen") — Rahul Jain

If you want you can also use a HTML <a>-Tag and in the href you just put: href='@Url.Action("AddValue", "DocGen")'

So the complete <a> would be:

<a href='@Url.Action("AddValue", "DocGen")' class="btn btn-primary">Add Value</a>

it's also a preferable solution if you need to integrate url within some more complicated structure :)

You're using the wrong overload of Action Link method, as you can see here: https://msdn.microsoft.com/en-us/library/system.web.mvc.html.linkextensions.actionlink(v=vs.118).aspx

The signature of the simplest method including controller name is:

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

Which means you need to provide one more object to your call, or one less and use:

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

So for example: @Html.ActionLink("Add Value", "AddValue", "DocGen") should do the job or:

@Html.ActionLink("Add Value", "AddValue", "DocGen", new{}, new { @class = "btn btn-primary" })

within the params object you'll probably want to pass some id or confirguration :)

@Desperado not really as you have overload of string, string, object, object, which is a perfect match for the arguments provided by OP, just that then "DocGen" is passed as object routeValues. It's easy to debug and check :)
