如何将父母/孩子DATAGRIDVIEW出口到EXCEL？ [英] HOW TO EXPORT A PARENT/CHILD DATAGRIDVIEW TO EXCEL?

问题描述

例如，我的数据库中有两个表：



CustomerTable

Id - PK

名称

年龄



OrderTable

OrderId - PK

产品

数量

Id- FK





我想在excel中导出数据。格式如下：



--- [新行] ------ 1 Justin 24y / o >
--- [新行] ----------------- 1，壁球，3

- - [新行] ----------------- 2，甜瓜，2

[空间]

--- [新行] ------ 2 Kristy 34y / o

--- [新行] ----------------- 4，苹果，3

--- [新行] ----------------- 2，木瓜，2

[空间]





我在出口中知道的唯一方法就是这样：





--- [新行] ------ 1 Justin 24y / o 1，壁球，3

--- [新行] ------ 1 Justin 24y / o 2，甜瓜，2

--- [新行] ------- 2 Kristy 34y / o，4，apple，3

--- [新行] -------- 2 Kristy 34y / o，2，木瓜， 2



这是我正在使用的代码：



On Pageload（）



（在此处加入查询：选择Buyer_Table。*，Order_Table。*）

buyer_table.datasource = ds

buyer_table.databind（）

For example , I have two tables in my database:

CustomerTable
Id - PK
Name
Age

OrderTable
OrderId - PK
Product
Qty
Id- FK


I wanted to export the data in excel. with the format like this:

---[new row]------1 Justin 24y/o
---[new row]----------------- 1 , squash , 3
---[new row]----------------- 2 , melon , 2
[space]
---[new row]------2 Kristy 34y/o
---[new row]-----------------4 , apple , 3
---[new row]----------------- 2 , papaya , 2
[space]


The only way I know in exporting is just like this:


---[new row]------1 Justin 24y/o 1 , squash , 3
---[new row]------1 Justin 24y/o 2 , melon , 2
---[new row]-------2 Kristy 34y/o, 4 , apple , 3
---[new row]--------2 Kristy 34y/o, 2 , papaya , 2

This is the code I am using:

On Pageload()

(JOIN QUERY HERE : Select Buyer_Table.*, Order_Table.*)
buyer_table.datasource = ds
buyer_table.databind()

If ((Buyer_TableDataGridView.Columns.Count = 0) Or (Buyer_TableDataGridView.Rows.Count = 0)) Then
         Exit Sub
     End If

Dim dset As New DataSet

     dset.Tables.Add()

  For i As Integer = 0 To Buyer_TableDataGridView.ColumnCount - 1
         dset.Tables(0).Columns.Add(Buyer_TableDataGridView.Columns(i).HeaderText)
     Next
     'add rows to the table
     Dim dr1 As DataRow
     For i As Integer = 0 To Buyer_TableDataGridView.RowCount - 1
         dr1 = dset.Tables(0).NewRow
         For j As Integer = 0 To Buyer_TableDataGridView.Columns.Count - 1
             dr1(j) = Buyer_TableDataGridView.Rows(i).Cells(j).Value
         Next
         '    dset.Tables(0).Rows.Add(dr1)
     Next


     Dim excel As New Microsoft.Office.Interop.Excel.Application
     Dim wBook As Microsoft.Office.Interop.Excel.Workbook
     Dim wSheet As Microsoft.Office.Interop.Excel.Worksheet

     wBook = excel.Workbooks.Add()
     wSheet = wBook.ActiveSheet()

     Dim dt As System.Data.DataTable = dset.Tables(0)
     Dim dc As System.Data.DataColumn
     Dim dr As System.Data.DataRow
     Dim colIndex As Integer = 0
     Dim rowIndex As Integer = 0

     For Each dc In dt.Columns
         colIndex = colIndex + 1
         excel.Cells(1, colIndex) = dc.ColumnName
     Next

     For Each dr In dt.Rows
         rowIndex = rowIndex + 1
         colIndex = 0
         For Each dc In dt.Columns
             colIndex = colIndex + 1
             excel.Cells(rowIndex + 1, colIndex) = dr(dc.ColumnName)

         Next
     Next

有人可以使用有用的代码在excel中进行这种输出我们两个表？

can someone has a useful code to make this kind of output in excel using two tables?
