I've got 2 views: Question and Answer. From the Question View, Detail Action I wanna redirect to Answer View, Create Action, so I've placed:
@Html.ActionLink(Model.QuestionId.ToString(), "Create", "Answer", "Answer", new { id = Model.QuestionId })
and in Answer View:
public ActionResult Create(string id)
{
(...)
return View();
}
But the id in Create(string id) is always null. How can I pass this value properly?
You are using a wrong overload of the ActionLink helper. It should be:
@Html.ActionLink(
Model.QuestionId.ToString(), // linkText
"Create", // actionName
"Answer", // controllerName
new { id = Model.QuestionId }, // routeValues
null // htmlAttributes
)
which would generate
<a href="/answer/create/123">123</a>
whereas you are using:
@Html.ActionLink(
Model.QuestionId.ToString(), // linkText
"Create", // actionName
"Answer", // controllerName
"Answer", // routeValues
new { id = Model.QuestionId } // htmlAttributes
)
which generates:
<a href="/Answer/Create?Length=6" id="123">123</a>
I think that now it's not difficult to understand why your anchor doesn't work.
You seem to have chosen wrong ActionLink overload. Try this:
@Html.ActionLink(Model.QuestionId.ToString(), "Create", "Answer", new { id = Model.QuestionId }, null)
