Determine if View is being rendered as Partial

Is there a way to determine if a view is rendering as a partial?

I'm hoping to extend the reuse of a partial that I'm writing by catching this...and if necessary assigning the appropriate layout to the View.

At the moment I'm just rendering it in a div, but I could also see us using it as a modal and possible it's own page.

(the modal shouldn't require any change so no worries there)

EDIT: To clear up what I'm asking.

I'm wondering if there is anyway to determine the difference between a view being rendered by...

/path/to/controller

and

Html.Partial("/path/to/view.cshtml")

Not sure if this is exactly what you're looking for, but I found this question when trying to do something similar. You can take advantage of the fact that code in _ViewStart.cshtml is only run when rendering a full view, so e.g. if you add

@{
    ViewBag.IsFullPage = true;
}

into a _ViewStart.cshtml file, you can then check this in your partial, e.g.

@if (ViewBag.IsFullPage != true)
{
    // do something only when rendered on its own
}

So if you are rendering a partial using PartialView from a controller endpoint, ViewBag.IsFullPage would be false, but if you render the partial using Html.Partial as part of a full view, it would be true.

Why not @if (Layout==null)? Still I would recommend another view for the "own" page and set the layout there.

Based on @Pheonixblade9 's response and the lack of other answers it doesn't appear like this is possible at the moment. I ended up just binding the Model of the View as bool and pass this value in when rendering the view/partial.

In your view (assuming Razor syntax):

@if(typeof(this) == Controller.PartialView)) //code

or

@if(this is Controller.PartialView) //code
