Retrieve the current view name in ASP.NET MVC?

Question

I have a partial view (control) that's used across several view pages, and I need to pass the name of the current view back to the controller - so if there's e.g. validation errors, I can re-draw the original view.

A workaround way to do it would be (in the controller methods)

var viewName = "Details"; // or whatever ViewData["viewName"] = viewName; return(View(viewName, customer)); 

and then in the partial itself, render it as

<input type="hidden" name="viewName"      value="<%=Html.Encode(ViewData["viewName"])%>" /> 

Question is - is there some property or syntax I can use to retrieve this directly instead of setting it from the controller? I've tried the obvious:

<input type="hidden" name="viewName"      value="<%=Html.Encode(this.Name)%>" /> 

but this doesn't work. What am I missing here?

Thanks.

Well if you don't mind having your code tied to the specific view engine you're using, you can look at the ViewContext.View property and cast it to WebFormView

var viewPath = ((WebFormView)ViewContext.View).ViewPath; 

I believe that will get you the view name at the end.

EDIT: Haacked is absolutely spot-on; to make things a bit neater I've wrapped the logic up in an extension method like so:

public static class IViewExtensions {     public static string GetWebFormViewName(this IView view) {         if (view is WebFormView) {             string viewUrl = ((WebFormView)view).ViewPath;             string viewFileName = viewUrl.Substring(viewUrl.LastIndexOf('/'));             string viewFileNameWithoutExtension = Path.GetFileNameWithoutExtension(viewFileName);             return (viewFileNameWithoutExtension);         } else {             throw (new InvalidOperationException("This view is not a WebFormView"));         }     } } 

which seems to do exactly what I was after.

I had the same problem and that's how I solved it:

namespace System.Web.Mvc {     public static class HtmlHelperExtensions     {         public static string CurrentViewName(this HtmlHelper html)         {             return System.IO.Path.GetFileNameWithoutExtension(                 ((RazorView)html.ViewContext.View).ViewPath             );         }     } } 

Then in the view:

var name = Html.CurrentViewName(); 

or simply

@Html.CurrentViewName()
