How to add Barcode to Local Reports (RDLC) before report rendering stage

How to add Barcode to Local Reports (RDLC) before report rendering stage using Bytescout BarCode SDK

Prerequisites:

  • Bytescout Barcode SDK
  • Microsoft .NET Framework 2.0 (or greater)
  • Microsoft Visual Studio 2005 (or greater) or Visual Web Developer 2005 Express Edition (or greater)
  • Microsoft SQL Server 2005 (any version) or greater with Adventure Works sample database installed

In the following guide we'll create a local report (RDLC file) which features barcoding capabilities by using Bytescout Barcode SDK.

Follow these steps:

  1. Open Visual Studio and create a new ASP.NET Website naming it “RDLCExampleWithBarcode”.

  2. Add new DataSet item to the project and name it “AdventureWorks.xsd”

    display barcodes in local reports add new dataset item

    Click Add button. You will be asked if you want to place the AdventureWorks.xsd file in the App_Code directory. Answer yes.

    VS2005: After that, the TableAdapter Configuration Wizard is automatically launched so please follow its steps.

    VS2008 and later: Right click the design surface and select Add > TableAdapter…

    display barcodes in local reports run table adapter

    This will also run TableAdapter Configuration Wizard. Follow its steps.

    In the first step 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')

    display barcodes in local reports tableadapter configuration

    Click Finish to close the wizard dialog box.

  3. Add a new custom Column to the DataTable just created and name it “Barcode”.

    display barcodes in local reports add new column to datatabl
  4. Change the data type of the Barcode column to System.Byte[] (Array of Byte). If the System.Byte[] data type is not listed you must type it manually.

    display barcodes in local reports change the data type of ba

    Save the AdventureWorks.xsd file.

  5. Now add a new Report item to the project and name it BarcodeReport.rdlc.

    display barcodes in local reports add new report item

    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).

    display barcodes in local reports report data source
  6. Please design the report so it looks like the following figure.

    display barcodes in local reports add image to barcode colum

    The report features a Table item with 3 columns: Product ID, Product Name and Barcode. Barcode column holds an image. 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.

    display barcodes in local reports value property of image

    Save the report.

  7. Create/Open an ASP.NET WebForm at design time and drag & drop a ReportViewer control onto it. NOTE: DO NOT select any report to display. We'll set up it by code next.
  8. Now, from the Solution Explorer, add a reference to Bytescout Barcode SDK assembly (Bytescout.BarCode.dll). Look for it in the installation directory.
  9. Write the following code in the Page_Load event procedure:

    C#:

    using System;
     
    using Bytescout.BarCode;
    using Microsoft.Reporting.WebForms;
     
    public partial class _Default : System.Web.UI.Page 
    {
     
        protected void Page_Load(object sender, EventArgs e)
        {
     
        // Fill the datasource from DB
        AdventureWorksTableAdapters.vProductAndDescriptionTableAdapter ta = 
            <externalLink xmlns="http://ddue.schemas.microsoft.com/authoring/2003/5"><linkText>new</linkText><linkUri>http://www.google.com/search?q=new+msdn.microsoft.com</linkUri></externalLink> AdventureWorksTableAdapters.vProductAndDescriptionTableAdapter();
     
        AdventureWorks.vProductAndDescriptionDataTable dt = 
            <externalLink xmlns="http://ddue.schemas.microsoft.com/authoring/2003/5"><linkText>new</linkText><linkUri>http://www.google.com/search?q=new+msdn.microsoft.com</linkUri></externalLink> AdventureWorks.vProductAndDescriptionDataTable();
        ta.Fill(dt);
     
        // Create and setup an instance of Bytescout Barcode SDK
        Barcode bc = <externalLink xmlns="http://ddue.schemas.microsoft.com/authoring/2003/5"><linkText>new</linkText><linkUri>http://www.google.com/search?q=new+msdn.microsoft.com</linkUri></externalLink> Barcode(SymbologyType.Code128);
     
        bc.RegistrationName = "demo";
        bc.RegistrationKey = "demo";
     
            bc.DrawCaption = false;
     
        // Update DataTable with barcode image
        foreach (AdventureWorks.vProductAndDescriptionRow row in dt.Rows)
     
        {
            // Set the value to encode
            bc.Value = row.ProductID.ToString();
     
            // Generate the barcode image and store it into the Barcode Column
            row.Barcode = bc.GetImageBytesPNG();
        }
     
        // Create Report Data Source
        Microsoft.Reporting.WebForms.ReportDataSource rptDataSource = 
            <externalLink xmlns="http://ddue.schemas.microsoft.com/authoring/2003/5"><linkText>new</linkText><linkUri>http://www.google.com/search?q=new+msdn.microsoft.com</linkUri></externalLink> ReportDataSource("AdventureWorks_vProductAndDescription", dt);
     
        ReportViewer1.LocalReport.DataSources.Add(rptDataSource);
        ReportViewer1.LocalReport.ReportPath = Server.MapPath("BarcodeReport.rdlc");
     
        ReportViewer1.LocalReport.Refresh();
        }
    }

    Visual Basic

    Imports Bytescout.BarCode
     
    Partial Class _Default
        Inherits System.Web.UI.Page
     
        Protected Sub form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles form1.Load
     
            ' Fill the datasource from DB
     
            Dim ta As New AdventureWorksTableAdapters.vProductAndDescriptionTableAdapter()
            Dim dt As New AdventureWorks.vProductAndDescriptionDataTable()
     
            ta.Fill(dt)
     
            ' Create and setup an instance of Bytescout Barcode SDK
            Dim bc As <externalLink xmlns="http://ddue.schemas.microsoft.com/authoring/2003/5"><linkText>New</linkText><linkUri>http://www.google.com/search?q=new+msdn.microsoft.com</linkUri></externalLink> Barcode(SymbologyType.Code128)
     
            bc.RegistrationName = "demo"
            bc.RegistrationKey = "demo"
            bc.DrawCaption = False
     
     
            ' Update DataTable with barcode image
            Dim row As AdventureWorks.vProductAndDescriptionRow
     
            For Each row In dt.Rows
                ' Set the value to encode
     
                bc.Value = row.ProductID.ToString()
                'Generate the barcode image and store it into the Barcode Column
     
                row.Barcode = bc.GetImageBytesPNG()
            Next
     
            'Create Report Data Source
     
            Dim rptDataSource As <externalLink xmlns="http://ddue.schemas.microsoft.com/authoring/2003/5"><linkText>New</linkText><linkUri>http://www.google.com/search?q=new+msdn.microsoft.com</linkUri></externalLink> Microsoft.Reporting.WebForms.ReportDataSource("AdventureWorks_vProductAndDescription", dt)
     
            Me.ReportViewer1.LocalReport.DataSources.Add(rptDataSource)
            Me.ReportViewer1.LocalReport.ReportPath = Server.MapPath("BarcodeReport.rdlc")
     
            Me.ReportViewer1.LocalReport.Refresh()
        End Sub
    End Class
  10. Run your application. You should get the barcode images displayed in the report.

    display barcodes in local reports run application

    ReportViewer control lets you to export the displayed report to Acrobat PDF as well as Microsoft Excel XLS. In both cases the barcode images are maintained.
