jQuery is your friend here. If you make an ajax call to say an ActionResult, then you can either return a json object or a partial view.

My preference is to return a partial view and then replace the contents of the div with the resultant html.

So;

public ActionResult jQueryTagDelete(string SomeParametersMaybe)
{
    return PartialView("TagList", tags.OrderBy(x => x.keyword1));
}

And you jQuery code;

    function deleteTag(tagName) {
        $.post("/Admin/jQueryTagDelete", { tag: tagName }, function(RETURNED_HTML) {
            document.getElementById("divTags").innerHTML = RETURNED_HTML;
        });
    }
