Lesson 6 - Insert Two Rows

• Dec 17, 2023
• 3 minutes to read

The link created in this lesson generates a document that contains two rows. The first row contains a check box brick in an unchecked state, and an empty brick. The second row is inserted to display the check box in the checked state.

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 two rows into the content of a printing link, do the following.

1. To create a new printing link, declare a new class (Lesson6) derived from the Lesson5 class defined in the previous lesson. The new class overrides the CreateRow and CreateDetail methods to create two new bricks: check box and empty brick.

   C#

   using System.Drawing;
   using System.Windows.Forms;
   using DevExpress.XtraPrinting;
   // ...
   
   public class Lesson6 : Lesson5 {
       public Lesson6(PrintingSystem ps) : base(ps) {}
   
       protected override void CreateDetail(BrickGraphics graph) {
           // Center the text string.
           graph.StringFormat = graph.StringFormat.ChangeLineAlignment(StringAlignment.Center);
   
           // Add an unchecked check box brick with all borders displayed
           // to a specific location using the Light Sky Blue background color.
           graph.DrawCheckBox(new Rectangle(150, 0, 50, 50), 
              BorderSide.All, Color.LightSkyBlue, false);
   
           // Add an empty rectangle with all borders displayed
           // to a specific location using the Light Lavender background color.
           graph.DrawRect(new Rectangle(200, 0, 50, 50), 
               BorderSide.All, Color.Lavender, graph.BorderColor);
   
           base.CreateDetail(graph);
       }
   
       protected override void CreateRow(BrickGraphics graph) {
           base.CreateRow(graph);
   
           // Add a checked check box brick with all borders displayed
           // to a specific location using the Light Sky Blue background color.
           graph.DrawCheckBox(new Rectangle(150, top, 50, 50), 
               BorderSide.All, Color.LightSkyBlue, true);
       }
   }
   

   VB.NET

   Imports System.Drawing
   Imports System.Windows.Forms
   Imports DevExpress.XtraPrinting
   ' ...
   
   Public Class Lesson6
       Inherits Lesson5
       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)
   
           ' Add an unchecked check box brick with all borders displayed
           ' to a specific location using the Light Sky Blue background color.
           graph.DrawCheckBox(New RectangleF(150, 0, 50, 50), _
               BorderSide.All, Color.LightSkyBlue, False)
   
           ' Add an empty rectangle with all borders displayed
           ' to a specific location using the Light Lavender background color.
           graph.DrawRect(New RectangleF(200, 0, 50, 50), _
               BorderSide.All, Color.Lavender, graph.BorderColor)
   
           MyBase.CreateDetail(graph)
       End Sub
   
       Protected Overrides Sub CreateRow(ByVal graph As BrickGraphics)
           MyBase.CreateRow(graph)
   
           ' Add a checked check box brick with all borders displayed
           ' to a specific location using the Light Sky Blue background color.
           graph.DrawCheckBox(New RectangleF(150, top, 50, 50), _
               BorderSide.All, Color.LightSkyBlue, True)
   
       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) {
       Lesson6 lesson = new Lesson6(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 Lesson6(printingSystem1)
   End Sub
   

Launch the application and view the result.
