How can you find which view called which partial view in ASP.Net MVC

I would like to create a debugging helper function which I can use within an MVC partial view that will show what the rendering call hierarchy is.

For example if I place 

<%=Html.ShowRenderPath() %>

in my partial called endpoint.ascx and it is called from another view (midpoint.ascx) using 

<% Html.RenderPartial("endpoint") %>

and this was called from another view (index.aspx)

<% Html.RenderPartial("midpoint") %>

I want the helper function to write out :

~/views/test/index.aspx -> ~/views/test/midpoint.ascx -> ~/views/test/endpoint.ascx

can anyone point me in the right direction for getting the view which rendered a partial and so on?

This is so I can debug an already existing MVC app which uses many renderpatials and it would be much easier if we could see these rendering paths.

Thanks for the reply (upvote for your efforts :-)

the solution we have found instead was to update our custom view engine to output HTML comments which indicate the source of each view thereby giving a breakdown of the page construction in the source view. This was only outputted in debug mode.

Use StackTrace to generate a stack trace. From that you can identify the nested view/partial view classes (amongst other stuff). You should be able to separate out your views from the framework code through the namespaces.
