使用數據表作爲數據源填充網絡reportviewer

我有一個基於Web的報表查看器使用ASP.NET 4.5和reportviewer版本11以本地模式運行。我想用數據表填充它。數據表被填充，但是當我運行報告時，只有工具欄顯示沒有報告表或錯誤顯示。使用數據表作爲數據源填充網絡reportviewer

這裏是我的代碼：

Protected Sub ButtonRunReport_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ButtonRunReport.Click 

ReportViewer1.Reset() 
       ReportViewer1.LocalReport.ReportPath = "LMS/ParticipantListSummary.rdlc" 
       ReportViewer1.LocalReport.DataSources.Clear() 
       ReportViewer1.LocalReport.DataSources.Add(New ReportDataSource("LMS_ParticipantListSummary", GetDataTable("Participant List"))) 

ReportViewerDiv.Visible = True 
     ReportViewer1.LocalReport.SetParameters(parameters) 
       ReportViewer1.Visible = True 
       ReportViewer1.Style.Item("display") = "" 
       PanelOpeningMessage.Style.Item("display") = "none" 
       ReportViewer1.LocalReport.Refresh() 
End Sub 

Private Function GetDataTable(ByVal reportType As String) As DataTable 

     Dim dt As New DataTable 
     Dim connectionString = ConfigurationManager.ConnectionStrings("LMSConnectionString").ConnectionString 

     Dim cmdText As String = ... //command text string not shown. 

     Using cn As New SqlConnection(connectionString) 

     Dim dt As New DataTable() 

     Dim state As ConnectionState = connection.State 

     Dim adapter As New SqlDataAdapter(cmdText, cn) 

     If state = ConnectionState.Closed Then 
      connection.Open() 
     End If 

     adapter.Fill(dt) 

     If state = ConnectionState.Open Then 
      connection.Close() 
     End If 
     End Using 

    return dt 
End Function

任何想法？

謝謝，賈斯汀。

P.S.忘了提及這在報告查看器的第10版上運行良好。

問題解決了！

我有一個流氓reportviewer.visible = false導致報告不呈現給瀏覽器。

仍然不確定爲什麼它升級到asp.net 4.5和reportviewer 11之前工作。
