        cache: false,
        dataType: 'html',
        success: function (html) {
            $("#dynamicBody").html(html);
            $("#dynamicFooter").html("Hello");
        },
        error: function (xhRequest, ErrorText, thrownError) {
            $("#dynamicBody").html(xhRequest.status);
            $("#dynamicBody").html(ErrorText);
        }
    });

[HttpPost]
    public PartialViewResult GetListContents(int _PageID, int _LangID, int _BoxTypeID, int _ListTypeID, int _Count)
    {
        dynamic cOut = GetListContent(_PageID, _LangID, _BoxTypeID, _ListTypeID, _Count);
        return PartialView("DynamicPagingBoxInfo",null);
    }

    public dynamic GetListContent(int _PageID, int _LangID, int _BoxTypeID, int _ListTypeID, int _Count)
    {
        List<ipMedia_PageContentsCache> PageContent = new List<ipMedia_PageContentsCache>();
        ListPageDataProvider.GetDynamicBoxContent(ref PageContent, _PageID, _LangID,_Count * 10);
        ViewBag.PageListContents = PageContent;
        ViewBag.CurPageIndex = _Count;

may be an error is in line

url: "/GetListContents",

try use url: '@Url.Action('GetListContents','YourControllerName'), instead

You need to send back the actual html from your controller. Take a look at RenderPartial. I have used the following code to perform this function in the past (placed on a base controller that my controllers inherit from):

    protected string RenderPartialView(string viewName, object model)
    {
        if (string.IsNullOrEmpty(viewName))
        {
            viewName = ControllerContext.RouteData.GetRequiredString("action");
        }

        ViewData.Model = model;

        using (var sw = new StringWriter())
        {
            var viewResult = ViewEngines.Engines.FindPartialView(ControllerContext, viewName);
            var viewContext = new ViewContext(ControllerContext, viewResult.View, ViewData, TempData, sw);

            viewResult.View.Render(viewContext, sw);

            return sw.GetStringBuilder().ToString();
        }
    }
