Url.Action parameters?

Question

In listing controller I have,

 public ActionResult GetByList(string name, string contact)
 {        
     var NameCollection = Service.GetByName(name);    
     var ContactCollection = Service.GetByContact(contact);           
     return View(new ListViewModel(NameCollection ,ContactCollection));
 }

In ASPX page I call,

 <a href="<%:Url.Action("GetByList","Listing" , new {name= "John"} , new {contact="calgary, vancouver"})%>"><span>People</span></a>

I have a problem in the ASPX code... I can pull the records for the name john. but when I give the contact="calgary, vancouver", the webpage goes to error.

How can I call two parameters in the Url.Action. I tried the below but that seems wrong too.

  <a href="<%:Url.Action("GetByList","Listing" , new {name= "John" , contact= " calgary, vancouver" })%>"><span>People</span></a>

Answer 1

The following is the correct overload (in your example you are missing a closing } to the routeValues anonymous object so your code will throw an exception):

<a href="<%: Url.Action("GetByList", "Listing", new { name = "John", contact = "calgary, vancouver" }) %>">
    <span>People</span>
</a>

Assuming you are using the default routes this should generate the following markup:

<a href="/Listing/GetByList?name=John&amp;contact=calgary%2C%20vancouver">
    <span>People</span>
</a>

which will successfully invoke the GetByList controller action passing the two parameters:

public ActionResult GetByList(string name, string contact) 
{
    ...
}

@user787788, what problem are you getting? What do you mean not accepting two parameters? Who is not accepting? Are you getting an error message? Is your controller action not hit? Are you getting wrong values? Be specific. – Infecund

When i give two parameters, the aspx page is not even hitting the controller. its finding the error in the page itself. i have a defalut exception called something gone worng. the aspx goes there – Agamemnon

@user787788, what is the error? Exact message you are getting? – Infecund

the error is , you may have typed the address (URL) incorrectly. – Agamemnon

@DarinDimitrov, i know this is a very old post, but i saw you were online. I don't suppose you'd know how to pass a parameter dynamically (not hardcoded like "John")? – Eugeniusz

@Eugeniusz Here is an example of what you can place in your view file: '@Url.Action("GetOverviewAsDocument", "FileAssignment", new { customerId = ViewData["customerId"] } )' – Uta

This works for MVC 5:

<a href="@Url.Action("ActionName", "ControllerName", new { paramName1 = item.paramValue1, paramName2 = item.paramValue2 })" >
    Link text
</a>

What is item, as in item.paramValue1? – Inexcusable

item.paramValue1 could be any text/string you want – Possibility

Answer 3

you can returns a private collection named HttpValueCollection even the documentation says it's a NameValueCollection using the ParseQueryString utility. Then add the keys manually, HttpValueCollection do the encoding for you. And then just append the QueryString manually :

var qs = HttpUtility.ParseQueryString(""); 
qs.Add("name", "John")
qs.Add("contact", "calgary");
qs.Add("contact", "vancouver")

<a href="<%: Url.Action("GetByList", "Listing")%>?<%:qs%>">
    <span>People</span>
</a>

Here is another simple way to do it

<a class="nav-link"
   href='@Url.Action("Print1", "DeviceCertificates", new { Area = "Diagnostics"})\@Model.ID'>Print</a>

Where is @Model.ID is a parameter

And here there is a second example.

<a class="nav-link"
   href='@Url.Action("Print1", "DeviceCertificates", new { Area = "Diagnostics"})\@Model.ID?param2=ViewBag.P2&param3=ViewBag.P3'>Print</a>

Fireproof

Answer 5

You can also do the following at ASP.Net MVC

<a href="@Url.Action("GetByList", "Listing",new {area = "Admin"})'
+ @Model.Id + '?name ="John"&contact ="calgary, vancouver"'+'"'>
    <span>People</span>
</a>
