Question

以实用或在设计时向.Net PrintDocument对象添加页眉和页脚的最简单方法是什么？

具体来说，我正在尝试打印第三方网格控件（Infragistics GridEx v4.3），它采用PrintDocument对象并将其自身绘制到其中。

结果页面只包含网格及其内容 - 但是我想添加一个标题或标题来标识打印的报告，可能还有一个页脚来显示谁打印它，何时，最好是页码和总页数

我正在使用VB.Net 2.0。

感谢您的帮助！

Answer 1

printdocument对象为每个要打印的页面触发printpage事件。您可以使用printpageeventargs事件参数将文本/行/等绘制到打印队列中：

当您将其传递给网格时将其调整为WithEvents，以便您可以处理该事件。

按照booji-boy的回答，这就是我提出的问题（我已将其简化为示例目的）：

Private Sub btnPrint_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPrint.Click

        Dim oDoc As New Printing.PrintDocument
        oDoc.DefaultPageSettings.Landscape = True
        AddHandler oDoc.PrintPage, AddressOf PrintPage

        oDoc.DocumentName = "Printout"

        InfragisticsWinGrid.PrintPreview(InfragisticsWinGrid.DisplayLayout, oDoc)

    End If
End Sub


Private Sub PrintPage(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs)

    ' Draw title
    e.Graphics.DrawString("Report Title"), New Font("Arial", 16), Brushes.Black, 95, 70)

    ' Draw footer
    e.Graphics.DrawImage(DirectCast(mResources.GetObject("footer_logo"), Drawing.Bitmap), 95, e.PageBounds.Height - 87)
    Dim drawFont As New Font("Arial", 8.75)

    e.Graphics.DrawString("Report Title", drawFont, Brushes.Gray, 190, e.PageBounds.Height - 90)
    e.Graphics.DrawString("Printed", drawFont, Brushes.Gray, 190, e.PageBounds.Height - 76)
    e.Graphics.DrawString("Printed By", drawFont, Brushes.Gray, 190, e.PageBounds.Height - 62)

    ' Draw some grid lines to add structure to the footer information
    e.Graphics.DrawLine(Pens.Gray, 246, e.PageBounds.Height - 90, 246, e.PageBounds.Height - 48)
    e.Graphics.DrawLine(Pens.Gray, 188, e.PageBounds.Height - 75, 550, e.PageBounds.Height - 75)
    e.Graphics.DrawLine(Pens.Gray, 188, e.PageBounds.Height - 61, 550, e.PageBounds.Height - 61)

    e.Graphics.DrawString("Report", drawFont, Brushes.Black, 250, e.PageBounds.Height - 90)
    e.Graphics.DrawString(Date.Now.ToShortDateString & " " & Date.Now.ToShortTimeString, drawFont, Brushes.Black, 250, e.PageBounds.Height - 76)
    e.Graphics.DrawString("Andrew", drawFont, Brushes.Black, 250, e.PageBounds.Height - 62)

End Sub

我必须使用e.PageBounds.Height - x的值来使绘制的项目排成一行。

再次感谢Booji Boy指针 - 获取ReportPage.Graphics（）正是我所追求的：o）
