步驟：
STEP1.
各自建立報表 report1.rdlc & report2.rdlc 及報表來源

注意：
報表來源不可以有沒使用到的數據來源
不然會一直出錯，沒有 DataSet_dt 數據來源

STEP2.
在父報表Report2設定
欄位導覽 跳至報表Report1 (所要鑽取的報表)
並設定要給予的參數(Report_Parameter_3 參數值 是此欄位的值)
(此參數在 Report1 及 Report2 參數名稱要相同)

範例畫面：
主(父)報表Report2

鑽取下的報表Report1

延伸：
若有多個欄位 鑽研不同的Report
則...

  Select Case e.ReportPath
   Case "Parent"
    Me.List_Customers_OrderTotalTableAdapter.Fill(Me.MyDataSet1.List_Customers_OrderTotal)
    RptrDS = New ReportDataSource("DataSet_1", Me.MyDataSet1.Tables("List_Customers_OrderTotal"))

   Case "Level1"
    Me.Show_OrderDetailsTableAdapter.Fill(Me.MyDataSet1.Show_OrderDetails, Integer.Parse(sParameter))
    RptrDS = New ReportDataSource("DataSet_2", Me.MyDataSet1.Tables("Show_OrderDetails"))

   Case "Level2"
    Me.Show_ProductsTableAdapter.Fill(Me.MyDataSet1.Show_Products, Integer.Parse(sParameter))
    RptrDS = New ReportDataSource("DataSet_3", Me.MyDataSet1.Tables("Show_Products"))

   Case Else
    Me.List_Customers_OrderTotalTableAdapter.Fill(Me.MyDataSet1.List_Customers_OrderTotal)
    RptrDS = New ReportDataSource("DataSet_1", Me.MyDataSet1.Tables("List_Customers_OrderTotal"))
  End Select

延伸：
若要多筆資料分頁
則...
Step1.將設計的Table(無資料列 只留表頭或表尾) 拉進 List裡

Step2.設定List屬性

自己想的報表：(應該滿多人會被這樣要求的, 不然紙張很浪費!!)
這一張報表剛好佔A4紙3分之1頁面
今天我想把三筆資料弄在同一張頁面

解決方式1：(很笨的方式)
查詢的資料結合，將每三筆資料結合成一組。
例如：

原始DataSet From DataBase
SN     名字     地址
1        陳         屏  
2        張         桃  
......
n        n           n             n


自定義DataSet, 每三筆組成一筆, 透過原始 DataSet 來組合
群組      row1     row2     row3     row4     row5     row6     row7     row8     row9
1           1            陳         屏         2           張         桃         3           x           x
2           4            x            x          5            x           x           6           x           x
......
n           n-2         x            x          n-1         x           x           n           x           x


同一個List，同樣的表格畫三個,並分別放入 row1~row9
第一個表格 row1~row3 第二個表格 row4~row6 第三個表格 row7~row9
分頁設定則是依 "群組" 來分頁


若資料剛好不足3筆成一個record時
則沒資料列的地方要補空白
不然格式會跑掉
而且畫出來的格式 如果有顏色
則必須再報表設計時 設定如果沒有值 得border為白色
(1.不知從程式有沒有辦法處理 報表的設定)
(2.不要用hiden 因為格式也會跑掉)
當然如果紙張不是白色的 就依那個顏色
(1.就嘿嘿嘿...囧 自己慢慢選顏色， 缺點...)

解決方法2：結尾的分頁符號不要勾選

顯示畫面：

注意：
A4紙直式輸出 會自動弄三頁
A4紙橫式輸出 會自動弄二頁
若要輸出為中一刀 寬21 長14
則報表上也要設計為中一刀格式
否則輸出依然是A4格式輸出
中一刀設定
