Sitefinity MVC: How to get the content item Url in Detail view of the widget template

I have a custom module with custom List and Detail widget templates. In my List widget template, I can get the content Item url with this:

@foreach (var item in Model.Items)
{
 var navigateUrl = HyperLinkHelpers.GetDetailPageUrl(item, ViewBag.DetailsPageId, ViewBag.OpenInSamePage, Model.UrlKeyPrefix); 
}

and then:

<a href="@navigateUrl">

Why can't I do the same thing in my Detail widget template and get the full content Item url? Is there a different method to get the full Url of the page in Detail widget template in MVC?

I am getting these build errors:

CS1061 'ContentDetailsViewModel' does not contain a definition for 'Items' and no accessible extension method 'Items' accepting a first argument of type 'ContentDetailsViewModel' could be found (are you missing a using directive or an assembly reference?)

CS1061 'ContentDetailsViewModel' does not contain a definition for 'UrlKeyPrefix' and no accessible extension method 'UrlKeyPrefix' accepting a first argument of type 'ContentDetailsViewModel' could be found (are you missing a using directive or an assembly reference?)

CS0103 The name 'navigateUrl' does not exist in the current context

Solution

So if you need to implement yourself, use one of the overloads https://github.com/Sitefinity/feather/blob/8c0bcde57c27322d48084485694f32e0714d15ee/Telerik.Sitefinity.Frontend/Mvc/Helpers/HyperLinkHelpers.cs#L32

What's the usecase though, you need the current url, or it's like for a related content section or something?
