How to Generate Barcodes in RDLC in WinForms
Download Demo Package
Create A RDLC Report in Windows Forms
- Open your Visual Studio, then create a Windows Forms application.
- Create a "DataSet" with the name "AdventureWorks.xsd".
- Go to the Toolbox to select "Pointer", then drag & drop "Table Adapter" to the new DataSet.
- Define the connection to SQL Server AdventureWorks Sample Database.
- Use the following string as SQL Statement: "SELECT ProductID, Name FROM Production.vProductAndDescription WHERE (CultureID = N'en') ".
- Right click "vProductAndDescription" on the dataset to create a column named "Barcode", and change the data type to "System.Byte[]" in "Properties" window.
- Create a new "Report", insert a table to the report, and add three columns in the dataset to the report table details section.
- Drag and drop "Image" item to the last column, named as "Barcode".
- Switch to the "Properties" window, and set the following properties: set "Source" to Database; set "MIMEType" to "image/jpeg"; set "Value" to "=Fields!Barcode.Value".
- Select "Form1.cs[Design]", drag "ReportViewer" to Form1, and bind the data collection.
- Add "KeepAutomation.Barcode.RDLC.dll" to project reference.
- Copy the sample code into the method Form1_Load.
- Use "KeepAutomation.Barcode.RDLC" namespace and run your project.
C# Sample code
private void Form1_Load(object sender, EventArgs e)
{
// load data to the data table this.vProductAndDescriptionTableAdapter.Fill
this.vProductAndDescriptionTableAdapter.Fill(this.AdventureWorks.vProductAndDescription);
// create a linear barcode object
BarCode barcode = new BarCode();
// set barcode type
barcode.Symbology = KeepAutomation.Barcode.Symbology.DataMatrix;
barcode.X = 4;
barcode.Y = 4;
// draw barcodes for each data row
foreach (AdventureWorks.vProductAndDescriptionRow
row in this.AdventureWorks.vProductAndDescription.Rows)
{// set barcode encoding data value
barcode.CodeToEncode = row.ProductID.ToString();
// set drawing barcode image format
barcode.ImageFormat = System.Drawing.Imaging.ImageFormat.Png;
row.Barcode = barcode.generateBarcodeToByteArray();
}
this.reportViewer1.RefreshReport();
} VB Sample code
Private Sub Form1_Load(sender As Object, e As EventArgs)
' load data to the data table this.vProductAndDescriptionTableAdapter.Fill
Me.vProductAndDescriptionTableAdapter.Fill(Me.AdventureWorks.vProductAndDescription)
' create a linear barcode object
Dim barcode As New BarCode()
' set barcode type
barcode.Symbology = KeepAutomation.Barcode.Symbology.DataMatrix
barcode.X = 4
barcode.Y = 4
' draw barcodes for each data row
For Each row As AdventureWorks.vProductAndDescriptionRow In Me.AdventureWorks.vProductAndDescription.Rows
' set barcode encoding data value
barcode.CodeToEncode = row.ProductID.ToString()
' set drawing barcode image format
barcode.ImageFormat = System.Drawing.Imaging.ImageFormat.Png
row.Barcode = barcode.generateBarcodeToByteArray()
Next
Me.reportViewer1.RefreshReport()
