剑道网格导出为pdf

我对mvc和kendo库都比较新。在我的项目中,我需要一种方法将数据从Kendo Grid(http://demos.kendoui.com/web/grid/index.html)导出为PDF。

我实际上找到了一个很好的例子,但是在其中实体框架用于将数据传递给网格。以下是示例:http://www.kendoui.com/code-library/mvc/grid/export-grid-to-pdf.aspx

在我的项目中,我使用NHibernate来映射数据,然后将其传递给View中的模型。

不幸的是,我不完全理解示例中的代码,但我无法弄清楚如何更改代码。

示例:

控制器:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using Kendo.Mvc.UI;
using KendoMVCWrappers.Models;
using Kendo.Mvc.Extensions;
using System.Collections;
using System.IO;
using System.Text;
using iTextSharp.text;
using iTextSharp.text.pdf;

namespace KendoMVCWrappers.Controllers
{
    public class HomeController : Controller
    {
        private NwEntities db = new NwEntities();

        public ActionResult Index()
        {
            ViewBag.Message = "Modify this template to kick-start your ASP.NET MVC application.";

            return View();
        }

        public ActionResult Read([DataSourceRequest] DataSourceRequest request)
        {
           // DataSourceRequest i = request;
            return Json(db.Products.ToDataSourceResult(request)); 
        }

        public FileResult Export([DataSourceRequest]DataSourceRequest request)
        {
            IEnumerable products = db.Products.ToDataSourceResult(request).Data;

            // step 1: creation of a document-object
            var document = new Document(PageSize.A4, 10, 10, 10, 10);

            //step 2: we create a memory stream that listens to the document
            var output = new MemoryStream();
            PdfWriter.GetInstance(document, output);

            //step 3: we open the document
            document.Open();

            //step 4: we add content to the document
            var numOfColumns = 4;
            var dataTable = new PdfPTable(numOfColumns);

            dataTable.DefaultCell.Padding = 3;

            dataTable.DefaultCell.BorderWidth = 2;
            dataTable.DefaultCell.HorizontalAlignment = Element.ALIGN_CENTER;

            // Adding headers
            dataTable.AddCell("Product ID");
            dataTable.AddCell("Product Name");
            dataTable.AddCell("Unit Price");
            dataTable.AddCell("Quantity Per Unit");

            dataTable.HeaderRows = 1;
            dataTable.DefaultCell.BorderWidth = 1;

            foreach (Product prod in products)
            {
                dataTable.AddCell(prod.ProductID.ToString());
                dataTable.AddCell(prod.ProductName);
                dataTable.AddCell(prod.UnitPrice.ToString());
                dataTable.AddCell(prod.QuantityPerUnit);
            }

            // Add table to the document
            document.Add(dataTable);

            //This is important don't forget to close the document
            document.Close();

            // send the memory stream as File
            return File(output.ToArray(), "application/pdf", "Products.pdf");

        }


    }
}

                    columns.Bound(p => p.UnitPrice).Format("{0:c}");
                    columns.Bound(p => p.QuantityPerUnit);
                })
                .Events(ev => ev.DataBound("onDataBound"))

        .options.parameterMap({

        // Get the export link as jQuery object
        var $exportLink = $('#export');

        // Get its 'href' attribute - the URL where it would navigate to
        var href = $exportLink.attr('href');

        // Update the 'page' parameter with the grid's current page
        href = href.replace(/page=([^&]*)/, 'page=' + requestObject.page || '~');

        // Update the 'sort' parameter with the grid's current sort descriptor
        href = href.replace(/sort=([^&]*)/, 'sort=' + requestObject.sort || '~');

        // Update the 'pageSize' parameter with the grid's current pageSize
        href = href.replace(/pageSize=([^&]*)/, 'pageSize=' + grid.dataSource._pageSize);

        //update filter descriptor with the filters applied

        href = href.replace(/filter=([^&]*)/, 'filter=' + (requestObject.filter || '~'));

        $exportLink.attr('href', href);
    }
</script>

如果我理解正确读取功能用于将数据从Products数据库传递到网格。使用javascript创建DataSource请求对象?

如果我没有像Products这样的数据库模型,我怎么能改变我的代码?

在我的项目中,我使用Repository来获取IList所需的所有数据。如何使用上面的示例执行类似的操作:

IEnumerable products = db.Products.ToDataSourceResult(request).Data;

在我的代码下面?

回购:

公共类CzasPracyMaszynRepository {

public IList<CzasPracyMaszyn> GetCzasPracyMaszyn()
{
    using (ISession session = NHibernateHelper.OpenSession())
    {

        var myList = session.Query<CzasPracyMaszyn>();


        return myList.ToList();
    }
}

}

型号:

public class CzasPracyMaszyn
    {
        public virtual int ID { get; set; }
        public virtual string STANOWISKO { get; set; }
        public virtual int CZASPRACY { get; set; }
        public virtual int CZASAWARII { get; set; }
        public virtual int AWARIAFORMY { get; set; }
        public virtual int AWARIAROBOTA { get; set; }
        public virtual int AWARIAWTRYSKARKI { get; set; }
        public virtual int MOKRYSUROWIEC { get; set; }
        public virtual int PUSTE { get; set; }

    }

控制器:

public class TabeleController:Controller {

CzasPracyMaszynRepository _repositoryCzasPracyMaszyn;


public TabeleController()
{
    _repositoryCzasPracyMaszyn = new CzasPracyMaszynRepository();

}


public ActionResult CzasPracyMaszynTabela()
{
    IList<CzasPracyMaszyn> CzasPracyMaszyn = _repositoryCzasPracyMaszyn.GetCzasPracyMaszyn();
    return View(CzasPracyMaszyn);
}

}

我知道所有这些都很模糊,但我尽力描述我的问题。
