I needed to use a user control from a different controllers folder in a view.

Should be easy I thought, there’s probably an overload for the Html.RenderPartial that with the controller name.

Unfortunately, that’s not the case.

If you look at the solution layout below:

I needed to user the OtherControl.ascx from the Home controllers views.

Passing only the user control name to the Html.RenderPartial won’t work, and you’ll end up with an error like this:

Which is rather logical, as that’s the default behavior of the web forms view engine.

Overcoming the problem is rather strait forward :

1

<% Html.RenderPartial("../Other/OtherControl", new string[] { "ListItem1", "ListItemN" }); %>

Not the most elegant solution, but it works..
