Retrieving ActionLink parameter from URL

Question

I have the following:

@Html.ActionLink("Customer Number", "Search", new { Search = ViewBag.Search, q = ViewBag.q, sortOrder = ViewBag.CustomerNoSortParm, })

With both viewbag properties coming from the URL:

http://localhost:51488/Home/Search?Search=Postcode&q=test&sortOrder=CustomerNo

However the URL produced is:

http://localhost:51488/Home/Search?sortOrder=CustomerNo

with it not picking up either of the ViewBag values.

Answer 1

ViewBag doesn't come from the URL. It comes from the controller action. If you want to fetch query string parameters or parameters that were part of a POST request you could use the Request:

@Html.ActionLink(
    "Customer Number", 
    "Search", 
    new { 
        Search = Request["Search"], 
        q = Request["q"], 
        sortOrder = Request["CustomerNoSortParm"] 
    }
)
