The link created in this lesson generates a document that contains three rows and three columns. One more row is inserted to represent a detail header.

Tip

A complete sample project is available in the DevExpress Code Examples database at https://supportcenter.devexpress.com/ticket/details/e161/reporting-get-started-with-printing-library.

To insert three rows and three columns into the content of a printing link, do the following.

1. To create a new printing link, declare a new class (Lesson8) derived from the Lesson7 class defined in the previous lesson. The new class overrides the CreateDetailHeader method to add headers to all columns. The text is vertically and horizontally centered within these headers.

   C#

   using System.Drawing;
   using System.Windows.Forms;
   using DevExpress.XtraPrinting;
   // ...
   
   public class Lesson8 : Lesson7 {
       public Lesson8(PrintingSystem ps, Bitmap img) : base(ps, img) {}
   
       protected override void CreateDetailHeader(BrickGraphics graph) {
           // Center the text string horizontally and vertically.
           graph.StringFormat = new BrickStringFormat(StringAlignment.Center, StringAlignment.Center);
   
           // Set the brick font name to 'Comic Sans MS' and set the size to '12'.
           graph.Font = new Font("Comic Sans MS", 12); 
   
           // Set the background color to 'Light Green'.
           graph.BackColor = Color.LightGreen;
   
           // Add a text brick with all borders displayed to a specific location 
           // containing the "I" text string with Green font.
           graph.DrawString("I", Color.Green, new Rectangle(0, 0, 150, 25), BorderSide.All);
   
           // Add a text brick with all borders displayed to a specific location 
           // containing the "love" text string with Green font.
           graph.DrawString("love", Color.Green, new Rectangle(150, 0, 50, 25), BorderSide.All);
   
           // Add a text brick with all borders displayed to a specific location 
           // containing the "you" text string with Green font.
           graph.DrawString("you", Color.Green, new Rectangle(200, 0, 50, 25), BorderSide.All);
   
           // Set the line alignment.
           graph.StringFormat = graph.StringFormat.ChangeAlignment(StringAlignment.Near);
       }
   }
   

   VB.NET

   Imports System.Drawing
   Imports System.Windows.Forms
   Imports DevExpress.XtraPrinting
   ' ...
   
   Public Class Lesson8
       Inherits Lesson7
       Public Sub New(ByVal ps As PrintingSystem, ByVal img As Bitmap)
           MyBase.New(ps, img)
       End Sub
   
       Protected Overrides Sub CreateDetailHeader(ByVal graph As BrickGraphics)
           ' Center the text string horizontally and vertically.
           graph.StringFormat = New BrickStringFormat(StringAlignment.Center, StringAlignment.Center)
   
           ' Set the brick font name to 'Comic Sans MS' and set the size to '12'.
           graph.Font = New Font("Comic Sans MS", 12)
   
           ' Set the background color to 'Light Green'.
           graph.BackColor = Color.LightGreen
   
           ' Add a text brick with all borders displayed to a specific location 
           ' containing the "I" text string with Green font.
           graph.DrawString("I", Color.Green, New RectangleF(0, 0, 150, 25), BorderSide.All)
   
           ' Add a text brick with all borders displayed to a specific location 
           ' containing the "love" text string with Green font.
           graph.DrawString("love", Color.Green, New RectangleF(150, 0, 50, 25), BorderSide.All)
   
           ' Add a text brick with all borders displayed to a specific location 
           ' containing the "you" text string with Green font.
           graph.DrawString("you", Color.Green, New RectangleF(200, 0, 50, 25), BorderSide.All)
   
           ' Set the line alignment.
           graph.StringFormat = graph.StringFormat.ChangeAlignment(StringAlignment.Near)
   
       End Sub
   End Class
   

2. Next, modify the main form’s Load event handler to pass the Printing System of the Document Viewer and the image to the new link.

   C#

   using System;
   using System.Drawing;
   using System.Windows.Forms;
   using DevExpress.XtraPrinting;
   // ...
   
   private void Form1_Load(object sender, System.EventArgs e) {
       Bitmap img = WindowsFormsApplication1.Properties.Resources.fish;
       img.MakeTransparent();
       Lesson8 lesson = new Lesson8(printingSystem1, img);
   }
   

   VB.NET

   Imports System
   using System.Drawing;
   Imports System.Windows.Forms
   Imports DevExpress.XtraPrinting
   ' ... 
   
   Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs)
       Dim img As Bitmap = WindowsFormsApplication1.Properties.Resources.fish
       img.MakeTransparent()
       Dim lesson As New Lesson8(printingSystem1, img)
   End Sub
   

Launch the application and view the result.
