[Solved] File upload in detail Grid (MVC 3)

[jimmy]

Hi,
      I am using upload control for MVC(master/detail grid), the problem that i am facing is:  

Html.Telerik().Grid<Dingzhi.Models.ProductViewModel>()
         .Name("Grid")
         .DataKeys(keys => keys.Add(o=>o.ProductId))
         .ToolBar(commands => commands.Insert().ButtonType(GridButtonType.ImageAndText).ImageHtmlAttributes(new { style = "margin-left:0" }))
         .Columns(columns =>
         {
             columns.Bound(o => o.Name).Width(150);
             columns.Bound(o => o.No).Width(70);
             columns.Command(commands => { commands.Edit().ButtonType(GridButtonType.ImageAndText); commands.Delete().ButtonType(GridButtonType.ImageAndText); }).Width(280);
         })
         .DataBinding(dataBinding =>
            {
                dataBinding.Ajax()
                .Select("ProductList", "Product")
                .Insert("ProductInsert", "Product")
                .Update("ProductSave", "Product")
                .Delete("ProductDelete", "Product");
            })
            .ClientEvents(events => events.OnDetailViewExpand("onDetailViewExpand"))
            .DetailView(details => details.ClientTemplate(
                 Html.Telerik().TabStrip()
                     .Name("TabStrip<#= ProductId #>")
                     .SelectedIndex(0)
                     .Items(items =>
                     {

             }
             // Return an empty string to signify success
             //return Content("");
 }

@(Html.Telerik().Upload()
 .Name("attachments<#= ProductId #>") //=problem(public ActionResult Save(int productId, Enumerable<HttpPostedFileBase> attachments)
  .HtmlAttributes(new { id = "attachments<#= ProductId #>" })
 .Multiple(false)
 .Async(async => async
 .Save("Save", "Product", new { productId = "<#= ProductId #>" })
 .AutoUpload(true)
 )
 .ShowFileList(false)
 .ClientEvents(e => e.OnSuccess("onSuccess"))
 )

find a not good way:
 

function onDetailViewExpand(e) {
    var div = $(e.detailRow.cells[1]).find("div");
    //alert(e.detailRow.cells[1].innerHTML);
   var productid = div.attr("id").replace("TabStrip", "");
    $("#Grid").find("input[type=file]").each(function () {
        $(this).attr('id', $(this).parent().parent().attr("id"));
        $(this).attr("name", $(this).parent().parent().attr("id"));
    });

    var grid = $("#Grid").data('tGrid');
    grid.$rows().each(function () {
        if (this != e.masterRow) {
            grid.collapseRow(this);
        }
        else {
            $("#Grid").find("input[type=file]").each(function () {
                if ("attachments" + productid == $(this).attr("id")) {
                    $(this).attr('id', "attachments");
                    $(this).attr('name', "attachments");
                }
            });
        }
    });

}

Could you give me a good advice,Thanks!
