DataGrid另存为Excel
我将查询出来的记录集倒为电子表格。
我用的是 DataAdapter 的 DataSet, 利用DataView帮定到DataGrid控件。、
利用网上现有代码，
Dim xlApp As New Excel.Application
Dim xlBook As Excel.Workbook
Dim xlSheet As Excel.Worksheet
Dim rowIndex As Integer = 1
Dim colIndex As Integer = 0
xlBook = xlApp.Workbooks().Add
xlSheet = xlBook.Worksheets("sheet1")
Dim Table As New DataTable
Table = CreaTable()
'将所得到的表的列名,赋值给单元格
Dim Col As DataColumn
Dim Row As DataRow
For Each Col In Table.Columns
colIndex = colIndex + 1
xlApp.Cells(1, colIndex) = Col.ColumnName
Next
'得到的表所有行,赋值给单元格
For Each Row In Table.Rows
rowIndex = rowIndex + 1
colIndex = 0
For Each Col In Table.Columns
colIndex = colIndex + 1
xlApp.Cells(rowIndex, colIndex) = Row(Col.ColumnName)
Next
Next
With xlSheet
.Range(.Cells(1, 1), .Cells(1, colIndex)).Font.Name = "黑体"
'设标题为黑体字
.Range(.Cells(1, 1), .Cells(1, colIndex)).Font.Bold = True
'标题字体加粗
.Range(.Cells(1, 1), .Cells(rowIndex, colIndex)).Borders.LineStyle = 1
'设表格边框样式
End With
With xlSheet.PageSetup
.LeftHeader = "" & Chr(10) & "&""楷体_GB2312,常规""&10公司名称：" ' & Gsmc
.CenterHeader = "&""楷体_GB2312,常规""公司人员情况表&""宋体,常规""" & Chr(10) & "&""楷体_GB2312,常规""&10日 期："
.RightHeader = "" & Chr(10) & "&""楷体_GB2312,常规""&10单位："
.LeftFooter = "&""楷体_GB2312,常规""&10制表人："
.CenterFooter = "&""楷体_GB2312,常规""&10制表日期："
.RightFooter = "&""楷体_GB2312,常规""&10第&P页 共&N页"
End With
xlApp.Visible = True
Private Function CreaTable() As DataTable
Dim dt As New DataTable
dt = DataGrid1.DataSource()
Return dt
End Function
但到后来提示， dt = DataGrid1.DataSource()类型无法转换？？？（数据源用DataView帮定的）
是怎么回事情？？？ dt 为DataTable,
大概是将数据源的记录集，转到DataTable表个，倒为电子表格，但是总是提示类型不能转换？？？
急！！！！！！！！！！！！
Dim a As DataTable = CType(Me.DataGrid1.DataSource, DataView).Table
