MVC4 naming Partial View "_XXPartial" ..what's the expected controller name?

Question

I have the following Ajax.Actionlink

@Ajax.ActionLink("Register", "_RegisterPartial", "Home", null, new AjaxOptions { UpdateTargetId = "userLogon"})

Is the expected Controller function "_RegisterPartial" ??
If so, what's the real need to have the word Partial and the Underscore ??

Answer 1

You are using this overload, and so the expected controller name is Home.
