the very famous actionlink:
<%: Html.ActionLink("Back to List", "Index")%>
Now, this link is in my Details view. The Index view is a search page. The url of that looks like this:
http://localhost:50152/2011-2012/Instelling/Details/76?gemeente=Dendermonde&postcode=92**&gebruikerscode=VVKSO114421&dossiernr=114421%20&organisatie=CLB
as you can see, quite the amount of parameters. Obviously I want to keep all these parameters when I return to the Index page, so I need to add them in the ActionLink.
now, I'm tired of doing that manually, it's ok for 1, but not for 6. This should go a lot easier.
question: How do I return All parameters of the current url into the actionlink as optional routevalues.
I've been looking to Request.QueryString. It has to be something with that. I was thinking of writing some static method in Global.asax doing the job but no luck yet. maybe there is an easy way to do this which I dont know about??
Edit: This is what I came up with (which works)
In global.asax:
public static RouteValueDictionary optionalParamters(NameValueCollection c) {
RouteValueDictionary r = new RouteValueDictionary();
foreach (string s in c.AllKeys) {
r.Add(s, c[s]);
}
return r;
}
Details.aspx:
<%: Html.ActionLink("Back to List", "Index", MVC2_NASTEST.MvcApplication.optionalParamters(Request.QueryString))%>
where do I best put this code? not in global.asax I guess...
Edit 2:
using System;
using System.Web.Mvc;
namespace MVC2_NASTEST.Helpers {
public static class ActionLinkwParamsExtensions {
public static MvcHtmlString CustomLink(this HtmlHelper helper, string linktext) {
//here u can use helper to get View context and then routvalue dictionary
var routevals = helper.ViewContext.RouteData.Values;
//here u can do whatever u want with route values
return null;
}
}
}
<%@ Import Namespace="MVC2_NASTEST.Helpers" %>
...
<%: Html.ActionLinkwParams("Index") %>
