How to data binding custom objects to print barcode labels with Zebra ZPL-EPL printers and VB.NET or C# by using ThermalLabel SDK for .NET

Prerequisites
  • Neodynamic ThermalLabel SDK v4.0 for .NET
  • Microsoft .NET Framework 3.5 (or greater)
  • Microsoft Visual Studio 2008 / 2010
  • Microsoft Visual Studio 2008 / 2010 Express Editions (VB, C#)
  • Any Zebra Thermal Printer supporting ZPL (Zebra Programming Language) or EPL (Eltron Programming Language)
ThermalLabel SDK supports .NET Data Binding scenarios allowing you to print thermal labels bound to a data source such as custom .NET objects, XML files, Databases, ADO.NET, etc.

In this guide you will learn how to perform data binding with .NET Custom Objects to print barcode labels with Zebra ZPL or EPL printers by using ThermalLabel SDK for .NET

The following sample features a class called Product with two basic properties: Id and Name. A list of Product and a ThermalLabel objects will be used to perform data binding scenario printing a set of thermal labels for each product as shown in the following figure.
How to data binding custom objects to print barcode labels with Zebra ZPL-EPL printers and VB.NET or C# by using ThermalLabel SDK for .NET


IMPORTANT: To test the sample code you must have installed a Zebra ZPL-based or EPL-based thermal printer.

Follow these steps:
  • Download and install latest version of Neodynamic ThermalLabel SDK for .NET
  • Open Visual Studio 2008 / 2010 and create a Windows Forms application.
  • Add a reference to Neodynamic.SDK.ThermalLabel.dll assembly.
  • Add a Class file and name it Product. After that paste the following code into it:
    Visual Basic .NET
    Public Class Product
    
        Dim _id As String
        Dim _name As String
    
        Public Sub New(ByVal id As String, ByVal name As String)
            Me.Id = id
            Me.Name = name
        End Sub
    
        Public Property Id() As String
            Get
                Return _id
            End Get
            Set(ByVal value As String)
                _id = value
            End Set
        End Property
    
        Public Property Name() As String
            Get
                Return _name
            End Get
            Set(ByVal value As String)
                _name = value
            End Set
        End Property
    
    End Class
    
    Visual C# .NET
    public class Product
    {
        string _id;
        string _name;
        
        public Product(string id, string name)
        {
            this.Id = id;
            this.Name = name;
        }
    
        public string Id
        {
            get { return _id; }
            set { _id = value; }
        }
    
        public string Name
        {
            get { return _name; }
            set { _name = value; }
        }
    }
    
  • Add a button control onto the form and paste the following code in the click event handler of the button:
