If my urls looks like: www.mysite.com/1/home www.mysite.com/1/other-action www.mysite.com/1/another-action/?value=a
how can I switch the 1 parameter while invoking the same action with the same parameters and querystring values?
For example if I'm currently browsing www.mysite.com/1/another-action/?value=a I would like to obtain the necessary links to switch to www.mysite.com/2/another-action/?value=a . . www.mysite.com/x/another-action/?value=a
Url.Action seems not to help...
The general idea is clone the current RouteValueDictionary, change one value, and then build a new action link based on the new RouteValueDictionary. Here's an example. But you'd probably want to do this in a URL helper, rather than directly in the view:
<% var foo = new RouteValueDictionary();
foreach (var value in ViewContext.RouteData.Values)
{
foo.Add(value.Key, value.Value);
}
foo["id"] = 2;
var newUrl = Url.Action(foo["action"].ToString(), foo); %>
Thank you very much. Your solution does not restore the querystring, but I managed to add it by simply checking if Request.QueryString.Count is more than zero and eventually appending it to the Url.Action resulting string. I hoped there were a better solution, but I can live with this :-)
