asp.net-mvc - ASP.NET MVC 4 数据网格

Question

我是 ASP.NET MVC 的新手，想做一个简单的页面，使用 Entity 检索一些数据并将其显示在分页数据网格中。

谁能指出我正确的方向或教程等。

它只是检索和显示内容列表的概念证明。

为此，您可以使用 ASP.NET MVC jqGrid。

下面我提到了如何实现这一点的示例代码。

动作方法

public ActionResult JsonSalesCollection(DateTime startDate, DateTime endDate,
string sidx, string sord, int page, int rows)

 {
     SalesLogic logicLayer = new SalesLogic();
     List<Sale> context;

     // If we aren't filtering by date, return this month's contributions
     if (startDate == DateTime.MinValue || endDate == DateTime.MinValue)
      {
         context = logicLayer.GetSales();
      }
     else // Filter by specified date range
      {
          context = logicLayer.GetSalesByDateRange(startDate, endDate);
      }

     // Calculate page index, total pages, etc. for jqGrid to us for paging
     int pageIndex = Convert.ToInt32(page) - 1;
     int pageSize = rows;
     int totalRecords = context.Count();
     int totalPages = (int)Math.Ceiling((float)totalRecords / (float)pageSize);

     // Order the results based on the order passed into the method
     string orderBy = string.Format("{0} {1}", sidx, sord);
     var sales = context.AsQueryable()
                  .OrderBy(orderBy) // Uses System.Linq.Dynamic library for sorting
                  .Skip(pageIndex * pageSize)
                  .Take(pageSize);

      // Format the data for the jqGrid
      var jsonData = new
       {
         total = totalPages,
         page = page,
         records = totalRecords,
         rows = (
                from s in sales
                select new
                {
                   i = s.Id,
                   cell = new string[] {
                   s.Id.ToString(),
                   s.Quantity.ToString(),
                   s.Product,
                   s.Customer,
                   s.Date.ToShortDateString(), 
                   s.Amount.ToString("c")
                }
           }).ToArray()
          };

         // Return the result in json
         return Json(jsonData);
}

jQuery 设置

<script type="text/javascript">
var gridDataUrl = '/Home/JsonSalesCollection';
// use date.js to calculate the values for this month
var startDate = Date.parse('today').moveToFirstDayOfMonth();
var endDate = Date.parse('today');

jQuery("#list").jqGrid({

     url: gridDataUrl + '?startDate=' + startDate.toJSONString() + '&endDate=' +        endDate.toJSONString(),
     datatype: "json",
     mtype: 'GET',
     colNames: ['Sale Id', 'Quantity', 'Product', 'Customer', 'Date', 'Amount'],
     colModel: [
                  { name: 'Id', index: 'Id', width: 50, align: 'left' },
                  { name: 'Quantity', index: 'Quantity', width: 100, align: 'left' },
                  { name: 'Product', index: 'Product', width: 100, align: 'left' },
                  { name: 'Customer', index: 'Customer', width: 100, align: 'left' },
                  { name: 'Date', index: 'Date', width: 100, align: 'left' },
                  { name: 'Amount', index: 'Amount', width: 100, align: 'right'}],
     rowNum: 20,
     rowList: [10, 20, 30],
     imgpath: gridimgpath,
     height: 'auto',
     width: '700',
     pager: jQuery('#pager'),
     sortname: 'Id',
     viewrecords: true,
     sortorder: "desc",
     caption: "Sales"
});

</script>
