How to Generate Barcodes in RDLC Reports?

Follow the instructions below step by step:

1.Create a Windows Application.

CrystalWinApp

2.Add a new DataSet to the project.

CRDataSet

3.Add a TableAdapter to the newly created DataSet, and follow the wizard instructions to finish the configuring process.

CRTableAdapter

4.Add a new Column to the DataTable.

CRInsertColumn

5.Change the data type of the newly created Column by manually entering System.Byte[] there.

CRBarcodeImgDataType

6.Add a new Report item to the project.

RDLCLocalBarcodeReport

7.Click "Data" > "Show Data Sources" to view the data source.

RDLCDataSource

8.Drag and drop a Table control and a few other controls including an Image control onto the report.

RDLCDropTable

9.Change the properties of the Image control to connect it to a data table field with System.Byte[] data type.

RDLCImageProp

10. Drag and drop a ReportViewer control onto a Windows Form.

RDLCDropReportViewer

11. Connect the newly created ReportView control to the previously created Report.

RDLCChooseReport

12. From the Solution Explorer, add a reference to MW6.SDK.dll.

RDLCAddReference

13. Add the following code in the Form_Load event procedure, you could modify the code a bit to meet your application barcoding requirements.

C# Code

private void Form1_Load(object sender, EventArgs e)

{

int ActualWidth = 0;

int ActualHeight = 0;

this.ItemsTableAdapter.Fill(this.BarcodeData.Items);

// Create a BarcodeNet class instance

MW6.SDK.Barcode.BarcodeNet objBC = new MW6.SDK.Barcode.BarcodeNet();

objBC.SymbologyType = MW6.SDK.Barcode.enumSymbologyType.Code_128;

objBC.BarHeight = (float)1.0;

objBC.NarrowBarWidth = (float)0.07;

objBC.CheckDigit = false;

objBC.ShowText = true;

foreach (BarcodeData.ItemsRow dataRow in this.BarcodeData.Items.Rows)

{

System.IO.MemoryStream MS = new System.IO.MemoryStream();

objBC.Data = dataRow.ID.ToString();

// Get the actual barcode width and height

// Render the barcode on the computer screen

objBC.GetActualSize(true, null, ref ActualWidth, ref ActualHeight);

// Image size = barcode size + extra space

objBC.SetSize(ActualWidth + 10, ActualHeight + 20);

// Save the barcode image in the memory using the Jpeg format

objBC.SaveAsMemory(MS, System.Drawing.Imaging.ImageFormat.Png);

dataRow.BarcodeImg = MS.ToArray();

}

this.reportViewer1.RefreshReport();

}

VB.NET Code

Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

Dim ActualWidth As Integer

Dim ActualHeight As Integer

ActualWidth = 0

ActualHeight = 0

' Fill the DataTable

Me.ItemsTableAdapter.Fill(Me.BarcodeData.Items)

' Create a BarcodeNet class instance

Dim objBC As New MW6.SDK.Barcode.BarcodeNet()

objBC.SymbologyType = MW6.SDK.Barcode.enumSymbologyType.Code_128

objBC.BarHeight = 2.0f

objBC.NarrowBarWidth = 0.07f

objBC.CheckDigit = False

objBC.ShowText = True

Dim dataRow As BarcodeData.ItemsRow

For Each dataRow In Me.BarcodeData.Items.Rows

Dim MS As New System.IO.MemoryStream()

objBC.Data = dataRow.ID.ToString()

' Get the actual barcode width and height

' Render the barcode on the computer screen

objBC.GetActualSize(True, Nothing, ActualWidth, ActualHeight)

' Image size = barcode size + extra space

objBC.SetSize(ActualWidth + 10, ActualHeight + 20)

' Save the barcode image in memory using Jpeg format

objBC.SaveAsMemory(MS, System.Drawing.Imaging.ImageFormat.Jpeg)

dataRow.BarcodeImg = MS.ToArray

Me.reportViewer1.RefreshReport()

End Sub

14. Run the application to view the barcodes.
