mvc action link error message
What is wrong with this statement?
I`m having the following error:
Error 10 开发者_运维技巧'System.Web.Mvc.HtmlHelper' does not contain a definition for 'ActionLink' and the best extension method overload 'System.Web.Mvc.Html.LinkExtensions.ActionLink(System.Web.Mvc.HtmlHelper, string, string)' has some invalid arguments c:\Code\MvcUI\Views\Project\Index.aspx 17 22 MvcUI
Error 11 Argument '3': cannot convert from 'AnonymousType#1' to 'string' c:\Code\MvcUI\Views\Project\Index.aspx 17 54 MvcUI
The compiler says it all. There's no such extension method. You need to pass the action name as a second parameter:
<%= Html.ActionLink(
"Assign Users",
"Index",
new
{
Controller = "Users",
Action = "Index",
Query = "Index",
Page = 2932
}
) %>
To avoid repeating the action name you could use this extension:
<%= Html.ActionLink(
"Assign Users",
"Index",
"Users",
new
{
Query = "Index",
Page = 2932
},
null
) %>
UPDATE:
If you have the default routes setup:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default",
"{controller}/{action}/{id}",
new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
This will generate a link of the type: http://localhost:2199/Users/Index/2932?Query=Index
<%= Html.ActionLink(
"Assign Users",
"Index",
"Users",
new
{
Query = "Index",
Id = 2932
},
null
) %>
From your previous comment
I`m getting the following: localhost:2593/Users?Query=Index&Page=2932 I want to have: Users\Index\id=2932
This is what you need:
<%= Html.ActionLink("Assign Users",
"Index",
"Users",
new { id = 2932 },
null) %>
Your Index method may look like this:
public ActionResult Index()
{
//.....
}
Which means your url may read like so:
localhost:2593/Users/Index?id=2932
You could also make id a parameter in your action method. So your Index method definition may look like this in your controller:
public ActionResult Index(int id)
{
//.....
}
and your url would look like this
localhost:2593/Users/Index/2932
