FIX-數據綁定：「System.Data.DataRowView」不包含屬性名稱爲

create procedure St_Proc_GetUserReportforCurrentDayTask     
@userID int     
as     
    Begin     
     set NoCount on;     
     DECLARE @TODAY DATE      
     SET @TODAY = CONVERT(VARCHAR(10), GETDATE(), 111)     
     select CONVERT(VARCHAR,production.CalendarDate,101) + RIGHT (CONVERT(VARCHAR,production.CalendarDate , 100) ,7) as Date,     
     RegionAndProjectInfo.RegionProjectName as Region ,     
     County.CountyName as County,     
     WorkType.WorkTypeName as WorkType,     
     Task.TaskName as Task,  
     Production.VolumeProcessed as 'Volumes Processed',     
     Production.TimeSpent as 'Duration(HH:MM)'     
     from Production     
     inner join RegionAndProjectInfo     
     on     
     RegionAndProjectInfo.RegionProjectID=Production.RegionProjectID     
     inner join County     
     on     
     County.CountyID=Production.CountyID     
     inner join WorkType     
     on     
     WorkType.WorkTypeID=Production.WorkTypeID     
     inner join Task     
     on     
     Task.TaskID=Production.TaskID     
     where [email protected] and CalendarDate >= @TODAY     
    End

這是我的存儲過程，我在執行這個存儲過程和結果保存在數據集中，然後結合與網格這個數據集。FIX-數據綁定：「System.Data.DataRowView」不包含屬性名稱爲

private void BindGridOnPageLoad() 
    { 
     _production = new EmployeeQuotientCL.Production(); 
     _userEcode = Convert.ToString(Session["UserID"]); 
     int _userID = _production.GetUserIDFromDB(_userEcode); 
     dsUserTaskDetails = _production.GetTabularUsertaskDetails(_userID); 
     BindGridView(dsUserTaskDetails); 
    }

到這裏的每一件事情是好的。於是我得到了規定，以顯示時間（HH：MM）總網格view.I又增加了在頁面下面的代碼的頁腳： -

<div id="gridview"> 
      <asp:GridView ID="GVUserEnteredDetails" runat="server" ShowFooter="true" CssClass="mGrid" CellSpacing="2" onselectedindexchanged="GVUserEnteredDetails_SelectedIndexChanged" onrowdatabound="GridView1_RowDataBound">     
      </asp:GridView>

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) 
    { 
     if (e.Row.RowType == DataControlRowType.DataRow) 
     { 
      tp += Convert.ToDecimal(((DataRowView)e.Row.DataItem).Row["[Duration(HH:MM)]"]); 
     } 
     if (e.Row.RowType == DataControlRowType.Footer) 
     { 
      e.Row.Cells[0].Text = "Total Hours : "; 
      e.Row.Cells[1].Text = tp.ToString("c"); 
      e.Row.Cells[0].HorizontalAlign = HorizontalAlign.Right; 
      e.Row.Cells[1].HorizontalAlign = HorizontalAlign.Right; 
      e.Row.Font.Bold = true; 

     } 
    }

但是，當我調試即時得到這個錯誤： - 「數據綁定：‘System.Data.DataRowView’不包含名爲‘時間’的屬性。」我在做什麼錯誤以及如何解決它？任何建議和幫助將對我有所幫助。

你是右表綁定到'GridView'什麼？ – V4Vendetta 2012-07-13 10:48:22

是的，我指定在我的問題，直到數據綁定和只顯示網格的每件事情都工作正常，但因爲我曾嘗試添加頁腳，然後我得到這個錯誤。 – 2012-07-13 10:52:42

有點令人驚訝，你的'DataSource'顯示'持續時間......'（希望程序與你正在執行的過程相同） – V4Vendetta 2012-07-13 11:23:09

正如你在你面對你已表示爲HH數據的小數解析麻煩的評論提到：毫米

你應該使用TimeSpan總結所有這些值，而不是小數點。（TimeSpan具有從4.0解析確切的功能，但如果你是在一個較小的版本）

嘗試以這種方式

TimeSpan ts = DateTime.ParseExact("02:30", "HH:mm", CultureInfo.InvariantCulture).TimeOfDay; 
// instead of 02:30 you would have the string from your column passed in 

// you can add up the values in this fashion 
ts.Add(DateTime.ParseExact("08:30", "HH:mm", CultureInfo.InvariantCulture).TimeOfDay);

產生的時間跨度做它，你可以用它來顯示它您選擇，因爲它會與格式也有天數太多，或者你可以隨時顯示ts.TotalMinutes

希望這是你尋找出別的請更新相關部分

是的，其實我正在尋找。現在我可以在頁腳中填充總數。非常感謝 – 2012-07-16 11:56:58

嘗試使用在你的列名sqare支架，因爲它含有特殊字符。像，

tp += Convert.ToDecimal(DataBinder.Eval(e.Row.DataItem, "[Duration(HH:MM)]"));

按照你的做法，但是這個我得到這個異常「異常已被調用的目標拋出。」 – 2012-07-13 11:09:07

你能發表詳細的異常堆棧跟蹤嗎？ – 2012-07-13 11:23:36

您甚至可以嘗試：tp + = Convert.ToDecimal（（（DataRowView）e.Row.DataItem）.Row [「[Duration（HH：MM）]」）。但是它假定您使用Datatable或Dataset作爲數據源。 – 2012-07-13 11:26:06
