The link created in this lesson generates a document that contains two different bricks.

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 add a brick to a document created via a printing link, do the following.

1. To create a new printing link, declare a new class (Lesson5) derived from the Lesson4 class defined in the previous lesson. The new class overrides the CreateDetail method, and provides a virtual CreateRow method that inserts a row consisting of one brick under the previous brick.

   C#

   using System.Drawing;
   using DevExpress.XtraPrinting;
   // ...
   
   public class Lesson5 : Lesson4 {
       public Lesson5(PrintingSystem ps) : base(ps) {}
   
       protected override void CreateDetail(BrickGraphics graph) {
           // Center the text string.
           graph.StringFormat = graph.StringFormat.ChangeLineAlignment(StringAlignment.Center);
   
           base.CreateDetail(graph);
           CreateRow(graph);
       }
   
       protected virtual void CreateRow(BrickGraphics graph) {
           // Set the brick font name to 'Arial', set the size to '14', and set the bold attribute.
           graph.Font = new Font("Arial", 14, FontStyle.Bold);
   
           // Add a text brick with all borders to a specific location 
           // containing the "Good-bye!" text in blue font.
           graph.DrawString("Good-bye!", Color.Blue, 
               new Rectangle(0, top += 50, 150, 50), BorderSide.All);
       }
   }
   

   VB.NET

   Imports System.Drawing
   Imports DevExpress.XtraPrinting
   ' ...
   
   Public Class Lesson5
       Inherits Lesson4
       Public Sub New(ByVal ps As PrintingSystem)
           MyBase.New(ps)
       End Sub
   
       Protected Overrides Sub CreateDetail(ByVal graph As BrickGraphics)
           ' Center the text string.
           graph.StringFormat = graph.StringFormat.ChangeLineAlignment(StringAlignment.Center)
   
           MyBase.CreateDetail(graph)
           CreateRow(graph)
       End Sub
   
       Protected Overridable Sub CreateRow(ByVal graph As BrickGraphics)
           ' Set the brick font name to 'Arial', set the size to '14', and set the bold attribute.
           graph.Font = New Font("Arial", 14, FontStyle.Bold)
   
           top += 50
   
           ' Add a text brick with all borders to a specific location 
           ' containing the "Good-bye!" text in blue font.
           graph.DrawString("Good-bye!", Color.Blue, _
               New RectangleF(0, top, 150, 50), BorderSide.All)
       End Sub
   End Class
   

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

   C#

   using System;
   using System.Windows.Forms;
   using DevExpress.XtraPrinting;
   // ...
   
   private void Form1_Load(object sender, System.EventArgs e) {
       Lesson5 lesson = new Lesson5(printingSystem1);
   }
   

   VB.NET

   Imports System
   Imports System.Windows.Forms
   Imports DevExpress.XtraPrinting
   ' ... 
   
   Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs)
       Dim lesson As New Lesson5(printingSystem1)
   End Sub
   

Launch the application and view the result.
