是否可以將數據從Excel導入jQGrid？

Question

是否有可能從一個Excel文件的jqGrid導入數據在ASP.NET MVC 4

我看看這個例子here但它不正是談論從Excel文件導入數據。我試圖解決它，但數據不顯示在jqGrid上。我所得到的只是一張只有標題的空表。任何幫助將是巨大的:)

我查看代碼：jqGrid的：

<table id="jQGridDemo"></table> 
<div id="jQGridDemoPager"></div> 

<script type="text/javascript"> 
jQuery("#jQGridDemo").jqGrid({ 
    url: 'TopPlayedInVenueList', 
    datatype: "json", 
    colNames: ['Id', 'First Name', 'Last Name', 'Last 4 SSN', 'Department', 
      'Age'], 
    colModel: [ 
    { name: '_id', index: '_id', width: 20, stype: 'text' }, 
    { name: 'FirstName', index: 'FirstName', width: 150 }, 
    { name: 'LastName', index: 'LastName', width: 150 }, 
     { name: 'LastSSN', index: 'LastSSN', width: 100 }, 
    { name: 'Department', index: 'Department', width: 80, align: "right" }, 
    { name: 'Age', index: 'Salary', width: 80, align: "right" } 
], 
    rowNum: 10, 
    sortname: 'id', 
    viewrecords: true, 
    sortorder: "desc", 
    caption: "List Employee Details" 
}); 
</script> 

我的控制器代碼：

public JsonResult TopPlayedInVenueList() 
    { 
     try 
     { 
      if (Request.IsAuthenticated == true) 
      { 
       string Path = @"C:\\1.xls"; 

       OleDbConnection con = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source= '" + Path + "';Extended Properties=" + (char)34 + "Excel 8.0;IMEX=1;" + (char)34 + ""); 

       OleDbDataAdapter da = new OleDbDataAdapter("select * from [All$A2:Z]", con); 

       //OleDbDataAdapter da = new OleDbDataAdapter("select * from [All$]", con); 

       con.Close(); 

       System.Data.DataTable data = new System.Data.DataTable(); 

       da.Fill(data); 

       List<TopPlayedInVenue> daa = new List<TopPlayedInVenue>(); 

       foreach (DataRow p in data.Rows) 
       { 
        TopPlayedInVenue top = new TopPlayedInVenue() 
        { 
         TrackName = p.Field<string>("Track Name"), 
         ArtistName = p.Field<string>("Artist Name") 
        }; 

        daa.Add(top); 
       } 



       var newlist = daa.OrderBy(i => i.TrackName).ToList(); 

       return Json(daa); 

感謝提前:)

我試圖運行代碼和我得到關於的異常[全部$ A2：Z]

也試圖找到答案，但看起來像查詢不工作。

嘗試按循環中的名稱訪問每個工作表。

string Path = @"E:\\DemoXls.xls"; 
     var con = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source= '" + Path + "';Extended Properties=" + (char)34 + "Excel 8.0;IMEX=1;" + (char)34 + ""); 

     con.Open(); 
     DataTable mySheets = con.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null); 
     con.Close(); 

     var dt = new DataTable(); 
     var da = new OleDbDataAdapter(); 
     da.SelectCommand = new OleDbCommand(); 
     da.SelectCommand.Connection = con; 
     var query = "Select * from [{0}]"; 
     foreach (DataRow item in mySheets.Rows) 
     { 
      da.SelectCommand.CommandText = string.Format(query, item["TABLE_NAME"].ToString()); 
      da.Fill(dt); 
      //DO the mapping of DataTable to your List<T> 
     }
