i call an action controller in my view and when i set break point and watch the act of ajax function it work correctly on code behind but when back to function it not run 'success:function' and return error

$.ajax({
        type: "POST",
        url: "/GetListContents",
        data: { _PageID: PageID, _LangID: LangID, _BoxTypeID: 6, _ListTypeID: 8, _Count: CurPageIndex },
        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);
        }
    });

the GetListContents work on code behind but the result is error
tnx for advance

Update
this is my action controller code

[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;
        return PageContent;
    }

is your partial page expecting a model? is it strongly typed? you are passing null to it may be exception is thrown in the partial page while rendering –  3nigma Jul 16 '12 at 6:41
    
Is there any reason you're not using models and taking advantage of model binding? Using this standard technique you would need to write very little JavaScript. Additionally your controller would be less verbose. –  The Muffin Man Jul 16 '12 at 6:42
    
yes one variable is null and when partial view cant convert it to requested data and got error.. tnx Every Body –  Leon_SFS Jul 16 '12 at 6:58

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();
        }
    }

render partial in code behind? i cant use it or use in view? can you say more? –  Leon_SFS Jul 16 '12 at 6:24
    
You pass back the string from your controller action. I usually pass back json containing a success property and a view property with message when there is an error. The view would then contain the rendered html. –  Eben Roux Jul 16 '12 at 6:33
