試圖使用通過用戶輸入從datagridview生成的數據表

Question

我試圖發送我的數據表已使用用戶輸入過濾到報告，但報告只能接受數據集。我在這裏遇到的問題是我不想通過SQL Server來完成。我想保留本地的信息。無論如何，我可以將數據表發送到報告，還是我SOL？

如何過濾datagridveiw並轉換成可用表：

// If & Try block 
    string filter = " (DateTime >= #" + startDateTime.ToString("MM/dd/yyyy HH:mm:ss") + "# And DateTime <= #" + endDateTime.ToString("MM/dd/yyyy HH:mm:ss") + "# And TagIndex =" + integerProdNum + ")"; 

    view.RowFilter = filter; 

    passingDataToReport = view.ToTable(); 

明明有如果，嘗試圍繞這些塊，但是這是我正在嘗試已被過濾回datagridview的轉換成一個數據表。

然後在報表查看器，我有以下代碼：

 DataSet Data = new DataSet("Data"); 
     reportData = DataSheet.getPassingDataToReport(); 
     reportData.TableName = "DateTimeValue"; 
     Microsoft.Reporting.WinForms.ReportDataSource source = new Microsoft.Reporting.WinForms.ReportDataSource("Data_DateTimeValue", reportData); 
     this.reportViewer1.LocalReport.DataSources.Clear(); 
     this.reportViewer1.LocalReport.DataSources.Add(source); 
     this.reportViewer1.DataBind(); 
     reportViewer1.LocalReport.Refresh(); 

我看了大量這並沒有發現任何的幫助。 Aside Aside; .DataBind（）與哪個指令關聯？

我不得不將數據表發送到PDF編寫器，並使用for和if來編寫循環。我發現你不能將運行時創建的數據表發送到報表查看器。代碼如下：

public void ExportToPdfTableFULL(DataTable dt, string path) 
    { 
     Document document = new Document(iTextSharp.text.PageSize.LETTER, 10, 10, 42, 35); 

     if (path.Equals(null) | path.Equals("")) { path = defaultFilename; } 
     try 
     { 
      PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(path + "_FULL.pdf", FileMode.Create)); 
     } 
     catch (System.NotSupportedException) 
     { 
      MessageBox.Show("Invalid File Path. The PDF was saved at " + defaultFilename); 
      path = defaultFilename; 

      PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(path + "_FULL.pdf", FileMode.Create)); 
     } 
     catch (Exception) 
     { 
      MessageBox.Show("Please Close Your PDF Viewer to Allow the " + "\nProgram to Overwrite or change the Filename"); 
     } 

     document.Open(); 

     try 
     { 
      iTextSharp.text.Image PNG = iTextSharp.text.Image.GetInstance("EisenmannLogo.png"); 

      document.Add(PNG); 
     } 
     catch (Exception) { } 

     Paragraph companyInfo = new Paragraph("\n" + companyName.Text + "-" + textBox4.Text + "\n" + phoneNumber.Text + " | " + textBox3.Text + "\n" + address.Text + "\n" + state.Text + ", " + zipCode.Text + " " + textBox2.Text + "\n"); 
     document.Add(companyInfo); 

     Paragraph TagName = new Paragraph("\n" + description.Text + "\n" + "\n"); 

     document.Add(TagName); 
     try 
     { 
      iTextSharp.text.Image Chart_Image = iTextSharp.text.Image.GetInstance(graphedTags[0] + "_chart.png"); 
      Chart_Image.ScalePercent(62f); 

      document.Add(Chart_Image); 
     } 
     catch(Exception) { } 
     Paragraph Disclaimer = new Paragraph("\n" + "*The data has been printed out at " + printOutInterval + " minute intervals to reduce PDF size.*" + "\n" + "\n"); 
     Disclaimer.Alignment = Element.ALIGN_CENTER; 
     int counterToShorten = 0; 
     for (int namesGraphed = 0; namesGraphed < graphedTags.Count; namesGraphed++) 
     { 
      Paragraph spacing = new Paragraph("\n" + "\n"); 

      document.Add(spacing); 

      PdfPTable table = new PdfPTable(dt.Columns.Count-1); 
      BaseFont bfTimes = BaseFont.CreateFont(BaseFont.TIMES_BOLD, BaseFont.CP1252, false); 

      iTextSharp.text.Font fontSize = new iTextSharp.text.Font(iTextSharp.text.Font.NORMAL, 8f, iTextSharp.text.Font.NORMAL, iTextSharp.text.BaseColor.BLACK); 
      iTextSharp.text.Font fontSize1 = new iTextSharp.text.Font(bfTimes, 14, iTextSharp.text.Font.NORMAL, iTextSharp.text.BaseColor.BLACK); 
      iTextSharp.text.Font fontSize2 = new iTextSharp.text.Font(bfTimes, 14, iTextSharp.text.Font.NORMAL, iTextSharp.text.BaseColor.WHITE); 
      PdfPCell cell = new PdfPCell(new Phrase(graphedTags[namesGraphed], fontSize2)); 
      cell.Colspan = 3; 
      cell.HorizontalAlignment = 1; 
      cell.BackgroundColor = new iTextSharp.text.BaseColor(0, 0, 0); 
      table.AddCell(cell); 
      for (int j = 1; j < dt.Columns.Count; j++) 
      { 
       PdfPCell cell2 = new PdfPCell(new Phrase(dt.Columns[j].ToString(), fontSize1)); 
       cell2.HorizontalAlignment = 1; 
       cell2.BackgroundColor = new iTextSharp.text.BaseColor(185, 185, 185); 
       table.AddCell(cell2); 
      } 
      table.HeaderRows = 1; 
      for (int p = 0; p < columnHeaders.Count; p++) { Console.WriteLine(columnHeaders[p]); } 


       document.Add(Disclaimer); 
       for (int i = 0; i < (dt.Rows.Count); i++) 
       { 
        if (columnHeaders.Contains("Tagname")) 
        { 
         if (graphedTags[namesGraphed].Equals(dt.Rows[i]["Tagname"].ToString())) 
         { 
          counterToShorten++; 
          if (counterToShorten >= printOutInterval) 
          { 
           for (int k = 1; k < (dt.Columns.Count); k++) 
           { 

            if (!dt.Rows[i][k].Equals(null)) 
            { 
             PdfPCell cell3 = new PdfPCell(new Phrase(dt.Rows[i][k].ToString(), fontSize)); 
             cell3.HorizontalAlignment = 1; 
             table.AddCell(cell3); 
             counterToShorten = 0; 
            } 
           } 
          } 
         } 

        } 
        if (columnHeaders.Contains("TagIndex")) 
        { 
         if (graphedTags[namesGraphed].Equals(dt.Rows[i]["TagIndex"].ToString())) 
         { 
          counterToShorten++; 
          if (counterToShorten >=printOutInterval) 
          { 
           for (int k = 1; k < (dt.Columns.Count); k++) 
           { 
            int mulitplier = 10 * i; 
            if (!dt.Rows[i][k].Equals(null)) 
            { 
             PdfPCell cell3 = new PdfPCell(new Phrase(dt.Rows[i][k].ToString(), fontSize)); 
             cell3.HorizontalAlignment = 1;

        } 
       } 


      document.Add(table); 
     } 
     document.Close();
