how to pass multiple parameter to controller via actionlink and output in the view?

Question

I'm fairly new to asp.net mvc3 and I am having a hard time figuring this out. I have an actionlink which i want to include a parameter and pass to my Index Method

@Html.ActionLink("Click here", "Index", "Customer", new { customerid = item.custId}, new {       @class = "partiallink" })

How do i receive it from the controller? considering that there is no method parameter in my Index Action method and also how do I output the parameter in the view?

I guess what I'm trying to say is pass it to some controller method and still returns the Index page with the paramters

Are you trying to pass customerid to Index? But it contains no parameters. — Brian, Sep 07 '12 at 18:17

All parameters that you pass to action link become a querystring parameter i.e.

@Html.ActionLink("Click here", "Index", "Customer", new { customerid = 111, someOtherParameter = 222, anotherParameter = 333}

transfer to link /Customer/Index?customerid=111&someOtherParameter=222&anotherParameter=333. You can get it in controller through Request.QueryStringproperty or map it through model binder if signature of Index action is:

ActionResult Index(int? customerid, int? someOtherParameter, string anotherParameter)
{
    .....
}

I don't know why the parameters I pass don't become part of the query string. Why is that? Does that mean it doesn't work for the current version of .net? — William, May 28 '22 at 23:52

Are you saying, on your Customer controller, you want to be able to pass either no value, or a customerid to your Index action, which returns the Index page?

Assuming you haven't changed the default route, you can alter your controller action to accept a nullable int, and then get your model based on whether the customerid is null:

    public ActionResult Index(int? customerid)
    {
        YourModelType model;
        if (customerid == null)
        {
            model = /* however you get your model when you don't have an id */
        }
        else
        {
            model = /* however you get your model when you have an id */;
        }

        return View("Index", model);
    }

You'll also need to update your routing engine to accept the optional customerid parameter:

        routes.MapRoute(
            "Customer", // Route name
            "Customer/{action}/{customerid}", // URL with parameters
            new { controller = "Customer", action = "Index", customerid = UrlParameter.Optional } // Parameter defaults
        );

You can use similar to below example

@Html.ActionLink("Click here", "Index", "Customer", new { ID= 111,UID =222}, null)

and in controller

[HttpGet,Route("Index/{ID}/{UID}")]
        public ActionResult EventView(int ID,int UID)
        {
        }

Please refer below link as well ,it is useful
