How to create local reports RDLC featuring barcode images in ASP.NETPrerequisites

Neodynamic Barcode Professional 3.0 (or greater) for ASP.NET (WebControl) Microsoft .NET Framework 2.0 (or greater) Microsoft Visual Studio 2005 or Visual Web Developer 2005 Express Edition.

NOTE: For VWD Express Edition, 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 for ASP.NET.Follow these steps:

Open Visual Studio and create a new ASP.NET Website naming it LocalReportWithBarcode.

Report's Data Source settingsData can be supplied to Local Reports either as custom Objects or as ADO.NET DataTables. In this guide we'll be exploring each data source scenario in details. So please choose the data source scenario you want to use first and then follow the steps for each of them:

o Using ADO.NET DataTables as data source of my local report o Using Custom Objects as data source of my local report

Using ADO.NET DataTables as data source of my local reportFollow these steps:

Add a new DataSet item to the project and name it AdventureWorks.xsd

Adding a Typed DataSet

Page 2: How to Create Local Reports RDLC Featuring Barcode Images in ASP

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

After that, the TableAdapter Configuration Wizard is automatically launched so please follow its 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

Finally click Finish to close the wizard dialog box.

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

Page 3: How to Create Local Reports RDLC Featuring Barcode Images in ASP

Adding a new Column to the DataTable for barcoding purpose

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.

Setting up the Barcode Column to System.Byte[] data type

Save the AdventureWorks.xsd file. Now add a new Report item to the project and name it BarcodeReport.rdlc

Page 4: How to Create Local Reports RDLC Featuring Barcode Images in ASP

Adding a local report (RDLC) 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)

The DataSet is available to be used in the report

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

The barcode report layout

The report features a Table item with 3 columns:

Page 5: How to Create Local Reports RDLC Featuring Barcode Images in ASP

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.

2º Column: It holds the Name field

3º Column: It holds the ProductModel field

Save the report. Now 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.

After that, from the Solution Explorer, add a reference to Barcode Professional for ASP.NET assembly: Neodynamic.WebControls.Barcodeprofessional.dll

Write the following code in the Page_Load event procedure.

Visual Basic .NET

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

'Fill the datasource from DB

Dim ta As New AdventureWorksTableAdapters.vProductAndDescriptionTableAdapter() Dim dt As New AdventureWorks.vProductAndDescriptionDataTable() ta.Fill(dt)

'Create an instance of Barcode Professional

Dim bcp As New Neodynamic.WebControls.BarcodeProfessional.BarcodeProfessional() 'Barcode settings

bcp.Symbology = Neodynamic.WebControls.BarcodeProfessional.Symbology.Code128 bcp.BarHeight = 0.25F

'Update DataTable with barcode image

Dim row As AdventureWorks.vProductAndDescriptionRow For Each row In dt.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 'Create Report Data Source

Dim rptDataSource As New 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

Visual C# .NET

protected void Page_Load(object sender, EventArgs e){ //Fill the datasource from DB AdventureWorksTableAdapters.vProductAndDescriptionTableAdapter ta = new AdventureWorksTableAdapters.vProductAndDescriptionTableAdapter(); AdventureWorks.vProductAndDescriptionDataTable dt = new AdventureWorks.vProductAndDescriptionDataTable(); ta.Fill(dt);

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

//Update DataTable with barcode image

Page 7: How to Create Local Reports RDLC Featuring Barcode Images in ASP

foreach (AdventureWorks.vProductAndDescriptionRow row in dt.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); }

//Create Report Data Source Microsoft.Reporting.WebForms.ReportDataSource rptDataSource = new Microsoft.Reporting.WebForms.ReportDataSource("AdventureWorks_vProductAndDescription", dt);

this.ReportViewer1.LocalReport.DataSources.Add(rptDataSource); this.ReportViewer1.LocalReport.ReportPath = Server.MapPath("BarcodeReport.rdlc"); this.ReportViewer1.LocalReport.Refresh();}

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 reportYou 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.

Page 12: How to Create Local Reports RDLC Featuring Barcode Images in ASP

Adding a Product Class item

You will be asked if you want to place the class file in the App_Code directory. Answer yes.

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

Page 13: How to Create Local Reports RDLC Featuring Barcode Images in ASP

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;

Page 14: How to Create Local Reports RDLC Featuring Barcode Images in ASP

} set { m_barcode = value; } }}

Add another new class item to the project and name it Catalog. This new class Catalog will be used as the object data source for our report. NOTE: In order for a class to qualify as an object data source, there should be a "Select method" that returns a collection of objects of the involved class and thus why we'll create this Catalog class.

Adding a Catalog Class item

You will be asked if you want to place the class file in the App_Code directory. Answer yes.

The Catalog class will allow us to add Product objects and features a "Select method" called GetProducts which returns a strongly typed collection of Product objects.

Please write the following Catalog class definition:

Visual Basic .NET

Public Class Catalog

Dim m_products As System.Collections.Generic.List(Of Product)

Public Sub New() m_products = New System.Collections.Generic.List(Of Product) End Sub

Page 15: How to Create Local Reports RDLC Featuring Barcode Images in ASP

Public Sub AddProduct(ByVal product As Product) m_products.Add(product) End Sub

Public Function GetProducts() As System.Collections.Generic.List(Of Product) Return m_products End Function

End Class

Visual C# .NET

public class Catalog{ private System.Collections.Generic.List<Product> m_products;

public Catalog(){

m_products = new System.Collections.Generic.List<Product>();}

public void AddProduct(Product product) { m_products.Add(product); }

public System.Collections.Generic.List<Product> GetProducts() { return m_products; }}

Save the class file and go to Build menu and click on Build Solution Now add a new Report item to the project and name it BarcodeReport.rdlc

Adding a local report (RDLC) to the project

Page 16: How to Create Local Reports RDLC Featuring Barcode Images in ASP

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)

The object data source is available to be used in the report

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