How have one child action & call it from multiple controller?

Question

I have one Child action that call it from it's own controller & return Views/Shared/PartialViewName belong to my child action. again repeat this in another controller and it do the same. every thing is ok. but i reapet child action in some controllers DRY

How share one child action among controllers is it possible like shared partial views in views folder?

I utulize below but doesn't work:

@Html.Action("actionName","ControllerName")

update: I don't use Areas

here's my code:

public class ItemCatController : Controller
    {
        [ChildActionOnly]
        public ActionResult PopulateTree() { return View("Tree", GetTree());  ... lots of other code }
     }

return view:

<h2>ItemCat Index</h2>
<hr />

<button onclick="New()">new</button>
<br />
@Html.Action("PopulateTree")

and this:

public class ItemController : Controller
    {
        *// repeat these codes again, this is aginst DRY principle.*
        [ChildActionOnly]
        public ActionResult PopulateTree() { return View("Tree", GetTree());  ... lots of other code }
     }

return this :

<h2>Index Item</h2>
<hr />

@Html.Action("PopulateTree")
<br />
