以横向格式打印和预览DataGridView

Question

 Private Sub btnPreview_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPreview.Click
    preview.PrintPreviewControl.Zoom = 1
    preview.Document = print
    print.PrinterSettings.DefaultPageSettings.Landscape = True
    preview.Show()

    AddHandler print.PrintPage, AddressOf print_PrintPage

End Sub

Protected Sub print_PrintPage(ByVal sender As Object, ByVal e As PrintPageEventArgs)
    Dim ColumnCount As Integer = DataGridView1.ColumnCount
    Dim RowCount As Integer = DataGridView1.RowCount

    Dim CellTopPos As Integer = print.PrinterSettings.DefaultPageSettings.Margins.Top

    For Row = 0 To RowCount - 1

        Dim CellLeftPos As Integer = print.PrinterSettings.DefaultPageSettings.Margins.Left

        For Cell = 0 To ColumnCount - 1

            Dim CellValue As String = DataGridView1.Rows(Row).Cells(Cell).Value.ToString()
            Dim CellWidth = DataGridView1.Rows(Row).Cells(Cell).Size.Width + 50
            Dim CellHeight = DataGridView1.Rows(Row).Cells(Cell).Size.Height

            Dim Brush As New SolidBrush(Color.Black)
            e.Graphics.DrawString(CellValue, New Font("Century Gothic", 10), Brush, CellLeftPos, CellTopPos)
            e.Graphics.DrawRectangle(Pens.Black, CellLeftPos, CellTopPos, CellWidth, CellHeight)

            CellLeftPos += CellWidth
        Next

        CellTopPos += DataGridView1.Rows(Row).Cells(0).Size.Height
    Next

End Sub

这是我预览和打印datagridview内容的代码.我尝试使用DefaultPageSettings代码,但它不起作用.我也试图以中心格式打印它

尝试设置PrintDocument的DefaultPageSettings属性,而不是PrinterSettings:

'PrintDocument1.PrinterSettings.DefaultPageSettings.Landscape = True
PrintDocument1.DefaultPageSettings.Landscape = True
