In a controller action I want to build some url's and the action is called
from AJAX.
I have some problems to build the url's.
In NavigationController:
public IEnumerable<NavigationDisplay> GetMenu()
{
//build url for FooController.Index
//build url for BarController.Index
//and so on
}
1. It seems that Controller.Context is not set when request is AJAX. Is
there any way to get it? This means that I can't do this in GetMenu:
var urlHelper = new UrlHelper(Context);
var url = urlHelper.For(DictHelper.Create(new string[] {"controller=Foo",
"action=index"}));
2. When I elaborated a little bit with the code in point 1 (in a none ajax
contoller action) I saw that it takes the area name from _current_
controller, which is different from area name for FooController. I'm
thinking of doing something like this instead (but maybe there is already a
way?):
private static string UrlFor<T>(string action)
where T : IController
{
var descriptor = ControllerInspectionUtil.Inspect(typeof (T));
string url;
if (string.IsNullOrEmpty(descriptor.Area))
{
url = string.Format("/{0}/{1}", descriptor.Name, action);
}
else
{
url = string.Format("/{0}/{1}/{2}", descriptor.Area, descriptor.Name,
action);
}
return url;
}
What is the recommended way to build url's for controllers (with area, name
and action)?
