的jqGrid没有返回JSON文本

Question

无法绑定我的jqGrid结合后，下面是我的代码：

试图绑定一些数据使用JSON，但不能给电网结合，通过控制器的jqGrid。在下面附上我的代码。

Controller Class: 

public class TransactionTypeController : Controller 
{ 
    // 
    // GET: /TransactionType/ 

    public ActionResult Index(EMM_New.Models.TransactionTypeModal TransactionType) 
    { 
     List<EMM_New.Models.TransactionTypeEntity> lst = TransactionType.GetTransactionType(); 
     ViewBag.TransactionTypeData = lst; 
     return View(); 
    } 

    public ActionResult GetGridData(string sidx, string sord, int page, int rows) 
    { 
     return Content(JsonHelper.JsonForJqgrid(GetDataTable(sidx, sord, page, rows), rows, GetTotalCount(), page), "application/json"); 
    } 

    public DataTable GetDataTable(string sidx, string sord, int page, int pageSize) 
    { 
     int startIndex = (page - 1) * pageSize; 
     int endIndex = page * pageSize; 

     DataTable table = new DataTable(); 
     table.Columns.Add("CustomerID", typeof(int)); 
     table.Columns.Add("ContactName", typeof(string)); 
     table.Columns.Add("Address", typeof(string)); 
     table.Columns.Add("City", typeof(string)); 
     table.Columns.Add("PostalCode", typeof(string)); 
     // 
     // Here we add five DataRows. 
     // 
     table.Rows.Add(25, "Ramesh", "Combivent", "Bangalore", "463456"); 
     table.Rows.Add(50, "Sam", "Enebrel", "Hosur", "463456"); 
     table.Rows.Add(10, "Christoff", "Hydralazine", "Bangalore", "463456"); 
     table.Rows.Add(21, "Janet", "Combivent", "Hosur", "463456"); 
     table.Rows.Add(100, "Melanie", "Dilantin", "Bangalore", "463456"); 
     return table; 
    } 

    public int GetTotalCount() {   
     return 10; 
    } 
} 

JsonHelper类：

public class JsonHelper 
{ 
    public static string JsonForJqgrid(DataTable dt, int pageSize, int totalRecords, int page) 
    { 
     int totalPages = (int)Math.Ceiling((float)totalRecords/(float)pageSize); 
     StringBuilder jsonBuilder = new StringBuilder(); 
     jsonBuilder.Append("{"); 
     jsonBuilder.Append("\"total\":" + totalPages + ",\"page\":" + page + ",\"records\":" + (totalRecords) + ",\"rows\""); 
     jsonBuilder.Append(":["); 
     for (int i = 0; i < dt.Rows.Count; i++) 
     { 
      jsonBuilder.Append("{\"i\":" + (i) + ",\"cell\":["); 
      for (int j = 0; j < dt.Columns.Count; j++) 
      { 
       jsonBuilder.Append("\""); 
       jsonBuilder.Append(dt.Rows[i][j].ToString()); 
       jsonBuilder.Append("\","); 
      } 
      jsonBuilder.Remove(jsonBuilder.Length - 1, 1); 
      jsonBuilder.Append("]},"); 
     } 
     jsonBuilder.Remove(jsonBuilder.Length - 1, 1); 
     jsonBuilder.Append("]"); 
     jsonBuilder.Append("}"); 
     return jsonBuilder.ToString(); 
    } 
} 

查看：

<table id="list" class="scroll" > 
</table> 
<div id="pager" class="scroll" style="text-align: center;"> 
</div> 


<script type="text/javascript"> 
    jQuery(document).ready(function() { 
     jQuery("#list").jqGrid({ 
      url: '/TransactionType/GetGridData/', 
      datatHomeype: 'json', 
      mtype: 'GET', 
      colNames: ['Customer ID', 'Contact Name', 'Address', 'City', 'Postal Code'], 
      colModel: [ 
       { name: 'CustomerID', index: 'CustomerID', width: 100, align: 'left' }, 
       { name: 'ContactName', index: 'ContactName', width: 150, align: 'left' }, 
       { name: 'Address', index: 'Address', width: 300, align: 'left' }, 
       { name: 'City', index: 'City', width: 150, align: 'left' }, 
       { name: 'PostalCode', index: 'PostalCode', width: 100, align: 'left' } 
      ], 
      pager: jQuery('#pager'), 
      rowNum: 10, 
      rowList: [5, 10, 20, 50], 
      sortname: 'CustomerID', 
      sortorder: "asc", 
      viewrecords: true, 
      caption: 'JqGrid from class Binding' 
     }).navGrid(pager, { edit: false, add: false, del: false, refresh: true, search: true }); 
    }); 
</script> 

能看到jqGrid的，但数据不填充....我在做什么worng.Please一些帮我整理出来..

Answer 1

datatHomeype：'json'？

应该是数据类型： 'JSON'

试图改变自己的JSON这样的：

{"total":1,"page":"1","records":10,"rows":[{"cell":["25","Ram","Combivent","Bangalore","463456"]}]}
