Question

我有一个Kendo Grid，第一列是超链接。每个超链接被绑定到一个pdf文件名.Pdf文件将在项目文件夹中。

网格：

  File Name          Date
----------------|--------
     file1.pdf  |12.03.2014
     file2.pdf  |13.03.2014

现在我点击此链接'file1.pdf'我希望将此文件名传递给模型。此Action链接也应该有一个动作'GetPdf'，它将返回PDFResult。单击此链接后，相应的pdf文件应在<object>标记的同一页面中打开。同样地，如果我点击第二个链接，那么file2.pdf应该在没有pagepostback的对象标签内打开。怎么实现这个？这是我的代码。我的观点：

 @(Html.Kendo().Grid<Myproject.Models.PdffilesModel>()
        .Name("grid")
        .Columns(columns =>
        {
columns.Bound(p => p.FileName)
                              .ClientTemplate(
        "<a  href='" +
            @Html.ActionLink("#=FileName#'", "GetPdf", "Home")+
            "/#= FileName #" +
        "</a>" );
 columns.Bound(c => c.CreatedDate).Width(70);
 })

        .HtmlAttributes(new { style = "height: 350px;" })
        .Scrollable()
        .Groupable()
        .Sortable()
        .Pageable(pageable => pageable
            .Refresh(true)
            .PageSizes(true)
            .ButtonCount(1))
        .DataSource(dataSource => dataSource
            .Ajax()
                      .ServerOperation(false)

            .Read(read => read.Action("Customers_Read", "Home"))
        )
)

HomeController：//这里我对文件名进行了硬编码，但它应该来自超链接点击操作

public FileStreamResult GetPdf(string filenmae)
        {
            FileStream fs = new FileStream("/pdfSample.pdf", FileMode.Open, FileAccess.Read);
            return File(fs, "application/pdf");
        }

绑定网格的数据源：

public ActionResult Customers_Read([DataSourceRequest]DataSourceRequest request)
        {
            return Json(GetAttachments().ToDataSourceResult(request));
        }

        private static IEnumerable<PdffilesModel>GetAttachments()
        {

            IEnumerable<PdffilesModel> finalresult ;
            List<PdffilesModel> list= new List<PdffilesModel>();
            var northwind = new PdffilesModel();

            northwind.FileName = "file1.pdf";           
            northwind.CreatedDate = new DateTime(2014,03,04).ToString("d");
            list.Add(northwind);           

            finalresult = list;

            return finalresult;
        }

当点击网格操作链接时，这是对象标签应与pdf结果绑定。

<object class="pdfdiv" id="ajaxpdf" data="@Url.Action("GetPdf")"></object>
