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

这是我的代码预览和打印我的datagridview的内容。我尝试使用defaultpagessettings代码，但它不起作用。我还试着以居中格式打印

Answer 1

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

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

Answer 2

可以这样使用CODE

    Dim preview As PrintPreviewDialog
    Dim PageSetup As PageSetupDialog
    PageSetup = New PageSetupDialog
    preview = New PrintPreviewDialog
    PageSetup.PageSettings = PrintDocument1.DefaultPageSettings
    PageSetup.ShowDialog()
    preview.PrintPreviewControl.Zoom = 1
    preview.Document = PrintDocument1
    preview.ShowDialog()
