How to print page numbers

[User (Old forums)]

By default, the grid is not printed with page numbers. In order to include page numbers when printing, you will need to create a class that derives from the GridPrintDocument class and override the OnPrintPage method (to be able to custom print the header or footer in this case, or other items if desired).

The following example demonstrates the minimum implementation required in order to print page numbers when printing the grid.

VB.NET Imports Xceed.Grid Public Class CustomGridPrintDocument   Inherits GridPrintDocument Private m_grid As GridControl Public Sub New(ByVal grid As GridControl)   MyBase.New(grid)   m_grid = grid End Sub Protected Overrides Sub OnPrintPage(ByVal e As System.Drawing.Printing.PrintPageEventArgs)       Dim gc As GraphicsContainer = e.Graphics.BeginContainer()        Try          MyBase.OnPrintPage( e )       Finally          e.Graphics.EndContainer(gc)       End Try        ‘ Print added text boxes (header and footers)       If Not e.Cancel And Me.IsCurrentPrintingPageSelected Then         Dim brush As New System.Drawing.SolidBrush(Color.Black)         e.Graphics.DrawString(“Page number ” +  Me.CurrentPageNumber.ToString(), m_grid.Font, brush, New RectangleF(e.MarginBounds.X, e.MarginBounds.Y – 20, e.MarginBounds.Width, e.MarginBounds.Height))         brush.Dispose()       End If End Sub End Class C# using Xceed.Grid; public class CustomGridPrintDocument : GridPrintDocument {   private GridControl m_grid;   public CustomGridPrintDocument( GridControl grid )     :base( grid )   {     m_grid = grid;   }   protected override void OnPrintPage( System.Drawing.Printing.PrintPageEventArgs e )   {     GraphicsContainer gc = e.Graphics.BeginContainer();          try     {       base.OnPrintPage( e );     }     finally          {               e.Graphics.EndContainer( gc );          }           // Print page number          if( !e.Cancel )     {       using( System.Drawing.SolidBrush brush = new System.Drawing.SolidBrush( Color.Black ) )       {         e.Graphics.DrawString(“Page number ” + this.CurrentPageNumber.ToString(), m_grid.Font, brush, new RectangleF( e.MarginBounds.X, e.MarginBounds.Y – 20, e.MarginBounds.Width, e.MarginBounds.Height ) );       }     }   } }

To use the custom GridPrintDocument, the following code must be used:

VB.NET Dim printDocument As New CustomGridPrintDocument(GridControl1) printDocument.Print() C# CustomGridPrintDocument printDocument = new CustomGridPrintDocument( gridControl1 );  printDocument.Print();

Keep in mind that if you call the grid’s Print or PrintPreview methods, the grid will always be printed with the default print document.
