Choose a Barcode Library

Before diving into the implementation, it's essential to select a barcode library that supports Crystal Reports and C#. One popular choice is the IronBarcode for .NET.

Czym jest IronBarcode

IronBarcode is a versatile .NET library that simplifies barcode generation and reading. With IronBarcode, you can effortlessly create various barcodes, including Code 128 and QR codes, by specifying the value to encode. It also supports resizing and customization. On the reading side, IronBarcode can extract barcode data from images or PDFs, making it ideal for inventory management and document tracking. Its user-friendly API ensures quick integration into your projects, and cross-platform support allows seamless development across different .NET versions. Whether you're a seasoned developer or a beginner, IronBarcode empowers you to work with barcodes efficiently.

Install IronBarcode Library

To install the IronBarcode library using the NuGet Package Manager Console, follow these steps:

Open the NuGet Package Manager Console. You can find it by going to View -> Other Windows -> Package Manager Console.

In the Package Manager Console, use the following command to install the IronBarcode library:

Install-Package BarCode

Press Enter to execute the command.

Alternatively, you can install IronBarcode library using the Manage NuGet Packages for Solution:

Wait for the NuGet Package Manager to download and install the IronBarcode library and its dependencies. Once the installation is complete, you'll see a confirmation message in the Package Manager Console.

Now, the IronBarcode library is installed in your project, and you can start using its features for barcode generation and reading.

Design Your Crystal Reports Barcode generator

Now, design the report layout, add database connections, and arrange the necessary fields. If you're new to this, follow the following steps.

1. Open Field Explorer => Database Field => Database Expert.

   

2. Expand Create a new Connection => OLE DB(ADO) => Make New Connection.

   

3. Select Microsoft OLE DB Data Source for SQL Server and click Next.

   

4. Provide the Server Name, Login Credential, and Database Name as shown below.

   

5. Press the Next button, a new window will appear, and then click Finish.

6. Select the table you want to add. In this case, select the Products table.

   

7. Click on the OK Button.

We have set up a Database Connection. Now, let's set up the Report layout.

Now, I have added a Text Box with the text "Barcode in Crystal report C#". I added a text box, and drag & drop the Product ID, Product Name, Product Price Field, and Product Barcode from the database fields and placed them inside the box as shown below.

See the Crystal Report Preview in Crystal Report Viewer.

Build and run the project. Oto wynik:

I have not downloaded the sample dataset package, ensuring I had the correct data file, and proceeded to create a Crystal Report in C# for comprehensive data visualization.

In this way, we can create a barcode in the Crystal Reports Application without downloading the Barcode Font. Similarly, we can also add a QR Code as per your requirement.
