[Solved] Correct placement of telerik extensions ?

[IQworks]

Hi,
   Sorry to double post, but this might need to be in another post.
   Refering to this post Tabstrp Visible property conflicting with selectedindex , I was given a method for a fix.
   The instructions make me think that a NavigationItemContainerExtensions.cs: Program exist somewhere to apply this method ...

public static string GetItemContentId<TComponent, TItem>(this TComponent component, TItem item)
            where TComponent : ViewComponentBase, INavigationItemContainer<TItem>
            where TItem : NavigationItem<TItem>, IContentContainer
        {
            return item.ContentHtmlAttributes.ContainsKey("id") ?
                   "{0}".FormatWith(item.ContentHtmlAttributes["id"].ToString()) :
                   "#{0}-{1}".FormatWith(component.Id, (component.Items.Where(i => i.Visible == true).IndexOf(item) + 1).ToString(Culture.Invariant));
        }

 just not sure where this .cs exists so I can add the above code ?
I looked in the telerik web.mvc.dll and saw the extensions namespace, but did not see the NavigationItemContainerExtensions.cs: ?  .
should i create an extensions folder and then create this class and add the methods ?
thanks for your time again.

Ok, i tried to create the class like this ....

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Telerik.Web.Mvc.UI;
using Telerik.Web.Mvc.Extensions;

namespace BCAnalytics.Extensions
{

    public static class NavigationItemContainerExtensions
    {

        public static string GetItemContentId<TComponent, TItem>(this TComponent component, TItem item)
            where TComponent : ViewComponentBase, INavigationItemContainer<TItem>
            where TItem : NavigationItem<TItem>, IContentContainer
        {
            return item.ContentHtmlAttributes.ContainsKey("id") ?
                   "{0}".FormatWith(item.ContentHtmlAttributes["id"].ToString()) :
                   "#{0}-{1}".FormatWith(component.Id, (component.Items.Where(i => i.Visible == true).IndexOf(item) + 1).ToString(Culture.Invariant));
        }

    }
}

This line gives me errors .... 

 

"#{0}-{1}".FormatWith(component.Id, (component.Items.Where(i => i.Visible == true).IndexOf(item) + 1).ToString(Culture.Invariant));
Its says for indexOf ... 
Error 1 'System.Collections.Generic.IEnumerable<TItem>' does not contain a definition for 'IndexOf' and no extension method 'IndexOf' accepting a first argument of type 'System.Collections.Generic.IEnumerable<TItem>' could be found (are you missing a using directive or an assembly reference?) C:\IQSys\BCAnalytics\BCAnalytics\Extensions\NavigationItemContainerExtensions.cs 20 103 BCAnalytics
Error 3 'Telerik.Web.Mvc.Extensions.EnumerableExtensions.IndexOf(System.Collections.IEnumerable, object)' is inaccessible due to its protection level C:\IQSys\BCAnalytics\BCAnalytics\Extensions\NavigationItemContainerExtensions.cs 20 103 BCAnalytics

Then, for Culture it says ... 
Error 4 The name 'Culture' does not exist in the current context C:\IQSys\BCAnalytics\BCAnalytics\Extensions\NavigationItemContainerExtensions.cs 20 131 BCAnalytics

I guess I am sort of stuck here ?

 

[IQworks]

  Perhaps I misunderstood ? 
  Should I be waiting for the version with this fix in it ? 
  Or am I just applying the fix incorrectly ?

  thanks for your time.
