How to create local reports RDLC featuring barcode images in .NET Windows Forms

Prerequisites
  • Neodynamic Barcode Professional SDK 1.0 (or greater) for .NET
  • Microsoft .NET Framework 2.0 (or greater)
  • Microsoft Visual Studio 2005/2008 or Visual Studio 2005/2008 Express Editions (Visual Basic 2005/2008 Express, Visual C# 2005/2008 Express, etc). NOTE: For Express Editions, installing the free add-in for ReportViewer is mandatory.
  • Microsoft SQL Server 2005 (any version) with AdventureWorks Database sample installed
In the following Step-By-Step Guide we're going to create a local report (RDLC file) which features barcoding capabilities by using Barcode Professional SDK for .NET.
Follow these steps:
Using ADO.NET DataTables as data source of my local report
Follow these steps:
  • Add a new DataSet item to the project and name it AdventureWorks.xsd

    Adding a Typed DataSet
    Adding a Typed DataSet


  • Add a new TableAdapter to the DataSet (Right-clicking on the DataSet design surface and selecting Add > TableAdapter... or by dragging & dropping a TableAdapter from the Toolbox).

    Adding a TableAdapter to the AdventureWorks DataSet
    Adding a TableAdapter to the AdventureWorks DataSet


    Follow the wizard steps. In the first step, please create a connection to the AdventureWorks SQL Server Database sample and click Next. In the second step, choose "Use SQL statements" and click Next. After that, please enter the following SQL Statement:

    SELECT ProductID, Name, ProductModel FROM Production.vProductAndDescription WHERE (CultureID = N'en')


    Specifying a SQL Statement that returns AdventureWorks Product info

  • After that, add a new custom Column to the DataTable just created and name it Barcode as is shown in the following figure

  • Change the data type of the Barcode column to System.Byte[] (Array of Byte). NOTE: the System.Byte[] data type is not listed and thus why you must type it manually.

  • Save the AdventureWorks.xsd file.
  • Now add a new Report item to the project.

  • The data source for the report should look like the following figure. NOTE: You can display Data Sources Window by selecting Data menu and then Show Data Sources (Shift+Alt+D)

  • Please design the report so it looks like the following figure.

    The report features a Table item with 3 columns:

    1º Column: It holds an Image item. Drag & drop an Image item into it and set its properties as is shown in the following figure. Notice that Value property of the Image item is bound to the Barcode column.

    The Image item's properties. The Value property is bound to Barcode Column.
    The Image item's properties. The Value property is bound to Barcode Column.


    2º Column: It holds the Name field

    3º Column: It holds the ProductModel field
  • Save the report.
  • Now Create/Open a Windows Form at design time and drag & drop a ReportViewer control onto it and set the local report to display.

  • After that, from the Solution Explorer, add a reference to Barcode Professional SDK for .NET assembly: Neodynamic.SDK.Barcode.dll
  • Write the following code in the Form_Load event procedure.
    Visual Basic .NET 
    Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

    'Fill the datasource from DB
    Me.vProductAndDescriptionTableAdapter.Fill(Me.AdventureWorks.vProductAndDescription)

    'Create an instance of Barcode Professional
    Dim bcp As New Neodynamic.SDK.BarcodeProfessional()
    'Barcode settings
    bcp.Symbology = Neodynamic.SDK.Symbology.Code128
    bcp.BarHeight = 0.25F

    'Update DataTable with barcode image
    Dim row As AdventureWorks.vProductAndDescriptionRow
    
    For Each row In Me.AdventureWorks.vProductAndDescription.Rows
        'Set the value to encode
        bcp.Code = row.ProductID.ToString()
        'Generate the barcode image and store it into the Barcode Column
        row.Barcode = bcp.GetBarcodeImage(System.Drawing.Imaging.ImageFormat.Png)
    Next
        
    Me.reportViewer1.RefreshReport()
End Sub
    Visual C# .NET 
    private void Form1_Load(object sender, EventArgs e)
{
    //Fill the datasource from DB    
    this.vProductAndDescriptionTableAdapter.Fill(this.AdventureWorks.vProductAndDescription);

    //Create an instance of Barcode Professional
    Neodynamic.SDK.BarcodeProfessional bcp = new Neodynamic.SDK.BarcodeProfessional();
    //Barcode settings
    bcp.Symbology = Neodynamic.SDK.Symbology.Code128;
    bcp.BarHeight = 0.25f;

    //Update DataTable with barcode image
    foreach(AdventureWorks.vProductAndDescriptionRow row in this.AdventureWorks.vProductAndDescription.Rows)
    {
        //Set the value to encode
        bcp.Code = row.ProductID.ToString();
        //Generate the barcode image and store it into the Barcode Column
        row.Barcode = bcp.GetBarcodeImage(System.Drawing.Imaging.ImageFormat.Png);
    }
        
    this.reportViewer1.RefreshReport();
}
  • That's it. Run your application. You should get the barcode images displayed on the report.

Using Custom Objects as data source of my local report
You can design local reports (RDLC) based on business objects defined in your application. In this scenario, an object data source is simply a collection of arbitrary objects. In this guide, we'll define a custom object with barcoding support that will be used as data source for our report.
Follow these steps:
  • Add a new class item to the project and name it Product.


    Adding a Product Class item
    Adding a Product Class item


    The Product class will feature basic info about products such is ID and Name as well as a special property called Barcode which will hold the barcode image for each product object.


    Please write the following Product class definition:
    Visual Basic .NET 
    Public Class Product

    Dim m_id As String
    Dim m_name As String
    Dim m_barcode As Byte()

    Public Sub New(ByVal id As String, ByVal name As String, ByVal barcode As Byte())
        m_id = id
        m_name = name
        m_barcode = barcode
    End Sub

    Public Property Id() As String
        Get
            Return m_id
        End Get
        Set(ByVal value As String)
            m_id = value
        End Set
    End Property

    Public Property Name() As String
        Get
            Return m_name
        End Get
        Set(ByVal value As String)
            m_name = value
        End Set
    End Property

    Public Property Barcode() As Byte()
        Get
            Return m_barcode
        End Get
        Set(ByVal value As Byte())
            m_barcode = value
        End Set
    End Property

End Class
    Visual C# .NET 
    public class Product
{
    string m_id;
    string m_name;
    byte[] m_barcode;

    public Product(string id, string name, byte[] barcode)
    {
        m_id = id;
        m_name = name;
        m_barcode = barcode;        
    }

    public string Id
    {
        get
        {
            return m_id;            
        }
        set
        {
            m_id = value;
        }
    }

    public string Name
    {
        get
        {
            return m_name;
        }
        set
        {
            m_name = value;
        }
    }

    public byte[] Barcode
    {
        get
        {
            return m_barcode;
        }
        set
        {
            m_barcode = value;
        }
    }
}
  • Save the class file and go to Build menu and click on Build Solution
  • Add a new Report item to the project.
