That I found there:
How to render an action link with an image?
and it works ok, but I admit that I'm really not used to make these and there are things that I do not understand.
For example, right now, there's a link on my image, made like this:
@Html.ImageLink("objectImage", "Object", "Details", null, Model[i].m_ObjThumbnailLink, Model[i].m_ObjName, null, null, null)
You see, my "details" action in my controller works with an id, so in this case I'd need the link to read as follow:
/Object/Details/1
1 for being the object ID that I can find in this object. But I don't know how to pass the id to the object because the method up there uses a RouteDictionaryValue and I have no idea how that works, so I end up having this link:
/Object/Details
And, of course, it does not work. How can I pass the ID or needed data to the HtmlHelper to create a link that actually works?
