ASP.NET MVC 4 Datagrid

2019-01-17 04:54发布

Im new to ASP.NET MVC and want to do a simple page that retrieves some data using Entity and displays it in a paging datagrid.

Can anyone point me in the right direction or to a tutorial etc.

Its just a proof of concept for retrieving a list of stuff and displaying it.

For that you can use ASP.NET MVC jqGrid.

Below I have mentioned sample code for how to achieve that.

Sample Image

enter image description here

Action Method

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 Set up

<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>
