I have a controller that is being called twice from an ActionLink call.
My home page has a link, that when clicked calls the Index method on the Play controller. An id of 100 is passed into the method. I think this is what is causing the issue. More on this below.
Here are some code snippets:
Home page:
<%= Html.ActionLink("Click Me", "Index", "Play", new { id = 100 }, null) %>
Play Controller:
public ActionResult Index(int? id)
{
var settings = new Dictionary<string, string>();
settings.Add("Id", id.ToString());
ViewData["InitParams"] = settings.ToInitParams();
return View();
}
Play view:
<%@ Page Title="" Language="C#" Inherits="System.Web.Mvc.ViewPage" %>
(html <head> omitted for brevity)
<body>
<form id="form1" runat="server" style="height:100%">
Hello
</form>
</body>
If I get rid of the parameter to the Index method, everything is fine. If I leave the parameter in place, then the Index method is called with 100 as the id. After returning the View, the method is called a second time with a parameter of null.
I can’t seem to figure out what is triggering the second call.
My first thought was to add a specific route like this:
routes.MapRoute(
"Play", // Route name
"Play/{id}", // URL with parameters
new {controller = "Play", action = "Index"} // Parameter defaults
);
This had no effect other than making a prettier looking link.
I am not sure where to go from here.
