Custom Printing

The chart document has a special kind of view called NChartPrintView allowing you to print the current chart contents on a printer device at the specified position (rectangle). The following example prints a custom header and footer and the chart contents on the page:

C#
Copy Code
...
 PrintDocument printDocument = new PrintDocument();
 printDocument.PrintPage += new PrintPageEventHandler(OnPrintPage);
... 

private void OnPrintPage(object sender, PrintPageEventArgs ev)
{
    RectangleF marginBounds = ev.MarginBounds;

    // create header and footer
    string header = "Custom Header";
    string footer = "Custom Footer";

    Font font = new Font("Arial", 15);
    Brush brush = new SolidBrush(Color.Black);

    // measure them
    SizeF headerSize = ev.Graphics.MeasureString(header, font);
    SizeF footerSize = ev.Graphics.MeasureString(footer, font);

    // draw header
    RectangleF headerBounds = new RectangleF(marginBounds.Left, marginBounds.Top, marginBounds.Width, headerSize.Height);
    ev.Graphics.DrawString(header, font, brush, headerBounds);

    // draw chart
    NRectangleF chartBounds = new NRectangleF(marginBounds.Left, headerBounds.Bottom, marginBounds.Width, marginBounds.Height - headerSize.Height - footerSize.Height);

    using (NChartPrintView printView = new NChartPrintView(chartControl.Document, ev.Graphics))
    {
  printView.Print(chartBounds);
    }

    // draw footer
    RectangleF footerBounds = new RectangleF(marginBounds.Left, marginBounds.Bottom - footerSize.Height, marginBounds.Width, footerSize.Height);
    ev.Graphics.DrawString(footer, font, brush, footerBounds);

    // dispose objects
    font.Dispose();
    brush.Dispose();
}
Visual Basic
Copy Code
....
Dim printDocument As New PrintDocument
AddHandler printDocument.PrintPage, AddressOf OnPrintPage
...

Private Sub OnPrintPage(ByVal sender As System.Object, ByVal ev As PrintPageEventArgs)
    Dim marginBounds As Rectangle = ev.MarginBounds

    ' create header and footer
    Dim header As String = "Custom Header"
    Dim footer As String = "Custom Footer"

    Dim font As New Font("Arial", 15)
    Dim brush As New SolidBrush(Color.Black)

    ' measure them
    Dim headerSize As SizeF = ev.Graphics.MeasureString(header, font)
    Dim footerSize As SizeF = ev.Graphics.MeasureString(footer, font)

    ' draw header
    Dim headerBounds As RectangleF = New RectangleF(marginBounds.Left, marginBounds.Top, marginBounds.Width, headerSize.Height)
    ev.Graphics.DrawString(header, Font, Brush, headerBounds)

    ' draw chart
    Dim chartBounds As RectangleF = New RectangleF(marginBounds.Left, headerBounds.Bottom, marginBounds.Width, marginBounds.Height - headerSize.Height - footerSize.Height)
    Dim printView As NChartPrintView = New NChartPrintView(m_ChartControl.Document, ev.Graphics)
    Try
       printView.Print(chartBounds)
    Finally
       CType(printView, IDisposable).Dispose()
    End Try

    ' draw footer
    Dim footerBounds = New RectangleF(marginBounds.Left, marginBounds.Bottom - footerSize.Height, marginBounds.Width, footerSize.Height)
    ev.Graphics.DrawString(footer, Font, Brush, footerBounds)

    ' dispose objects
    Font.Dispose()
    Brush.Dispose()
End Sub
