MvcSiteMapProvider MVC 5 custom ViewBase? - mvcsitemapprovider

Question

I have a problem after upgrading MvcSiteMapProvider MVC 4 to MVC 5.
I use a custom "pageBaseType" for my views, and it seems that MvcSiteMapProvider MVC 5 does
not allow that?
I keep getting the error:
The view at '~/Views/Shared/DisplayTemplates/SiteMapPathHelperModel.cshtml' must derive from WebViewPage, or WebViewPage<TModel>.
at #Html.MvcSiteMap().SiteMapPath().
However, my custom viewbase does inherit System.Web.Mvc.WebViewPage.
Am I missing something here?
If I remove the line #Html.MvcSiteMap().SiteMapPath() the page works fine, but without the sitemappath, of course.
Thanks in advance for any help!

Answer 1

I tried to reproduce your problem, but I am not getting the same error. Here is the project you can use to try to resolve your issue.
If your project has files in it with a .aspx extension, it will cause the NuGet package to install the templates for webpages (not razor) into your project in the /Views/Shared/DisplayTemplates/ directory. Check that directory to make sure that all of the files have a .cshtml extension.
If not, you can get the latest version of the .cshtml templates from here. Alternatively, you can copy them out of the \packages\MvcSiteMapProvider.Web.[installed version]\content\Views\Shared\DisplayTemplates\ folder in your project.

Ok, now I figured out what was missing:
I did not have the specific assembly binding in my web.config:
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="WebGrease" publicKeyToken="31bf3856ad364e35" />
<bindingRedirect oldVersion="0.0.0.0-1.5.2.14234" newVersion="1.5.2.14234" />
</dependentAssembly>
<dependentAssembly>
<assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35" />
<bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
</dependentAssembly>
<dependentAssembly>
<assemblyIdentity name="System.Web.WebPages" publicKeyToken="31bf3856ad364e35" />
<bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
</dependentAssembly>
<dependentAssembly>
<assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
<bindingRedirect oldVersion="0.0.0.0-5.2.0.0" newVersion="5.2.0.0" />
</dependentAssembly>
</assemblyBinding>
</runtime>
I saw this in the project you provided and added it my config... voila, it's working now.
Thank you for your help!

I met the same problem.
I tested a simple Test view with the following simple web.config, #Html.MvcSiteMap().SiteMapPath() worked fine.
<?xml version="1.0" encoding="utf-8"?>

But my web.config is much more complex. I met the error with stack trace:

[InvalidOperationException: The view at '~/Views/Shared/DisplayTemplates/SiteMapPathHelperModel.cshtml' must derive from WebViewPage, or WebViewPage<TModel>.]

I put the break point at #Html.MvcSiteMap().SiteMapPath(), in Watch windows #Html.MvcSiteMap() raised an exception
#Html.MvcSiteMap() 'System.Web.Mvc.HtmlHelper<object>' does not contain a definition for 'MvcSiteMap' and the best extension method overload 'MvcSiteMapProvider.Web.Html.HtmlHelperExtensions.MvcSiteMap(System.Web.Mvc.HtmlHelper)' has some invalid arguments
Could you show me which area is the most risky causing the error?
