i have a simple test controller defined as 

[Route("~/testAction/testcontroller/{viewhash}")]
public ActionResult ATest(string viewHash)
        {
            var viewname = commonDataCollection.Instance.WidgetHashList[viewHash];
            return Content($"Success hash by view name is: {viewhash}","text/html");
        }

this works if i call this from browser http://localhost:49359/testAction/testcontroller/FuMmWA1217dgnaT

the below works if i use actual action/controller name instead of attribute route value but if i try to do the same with Html Helper with routing defined such as :

@Html.Action("testAction", new { viewhash = "FuMmWA1217dgnaT",area="",controller= "testcontroller" });

or 

@Html.Partial("testAction", new { viewhash = "FuMmWA1217dgnaT",area="",controller= "testcontroller" });

or even when i am trying the render functions, i am getting following error:

Execution of the child request failed.

  • Pretty sure that what you're trying to do can't be done. Html.Action expects the name of the action method in your controller. Not anything to do with routes. – Tobias Sep 04 '19 at 20:07
  • @Tobias is there anyway to initiate this using route values, should i look for extension method approach... i must have this functionality to call right controller and get response. – Alok Sep 04 '19 at 20:19
  • @Tobias https://stackoverflow.com/questions/30382953/html-renderaction-with-route-name according to this i think its pretty much possible, not sure why mine is causing issues – Alok Sep 04 '19 at 20:27
  • What in that suggests that it's possible? – Gabriel Luci Sep 04 '19 at 20:34

    If you're going to hard code the route (which is what your doing if you use part of the route there) then there is no point in using `Html.Action` at all. Just hard code the whole URL. The whole point of using `Html.Action` is so that you can change the route in one place and not have to update it everywhere it is used. – Gabriel Luci Sep 04 '19 at 20:37
  • @GabrielLuci got it, but my problem is i want to hide the controller method name and only expose the friendly route to whoever is writing the view, now i can grab the data using ajax... but we want to render it server side due to project flow requires as such, if an extension method can do this lookup i am all upto it – Alok Sep 04 '19 at 20:46
  • How can you hide the controller method name from someone who is writing code in the same project? – Gabriel Luci Sep 04 '19 at 20:50
  • its an abstract system using different projects as plugins in IoC, so although the other users/developer can look through public methods using intellisense they dont know where to look for if we dont tell them – Alok Sep 04 '19 at 20:52
  • If they can use `Html.Action` then intellisense will help them find the name of the controller action. – Gabriel Luci Sep 04 '19 at 20:59
  • Mate, you are trying to do the very opposite of what you should. Exactly as pointed by @GabrielLuci, you completely missed the reason why these helper exist. And the linked question works only because the method name is the same as word used in the route. – Al Kepp Sep 04 '19 at 21:45
  • @AlKepp thanks for yours and Gabriel's comments, i think its not possible without hiding behind many methods so if i come up with something i will post solution here in future. – Alok Sep 05 '19 at 08:21
