How to data binding custom objects to print barcode labels with Zebra ZPL printers an

Prerequisites
- Neodynamic ThermalLabel SDK for .NET
- Microsoft .NET Framework 2.0 (or greater)
- Microsoft Visual Studio 2005 / 2008
- Microsoft Visual Studio 2005 / 2008 Express Editions (VB, C#, J#, and C++)
- Any Zebra Thermal Printer supporting ZPL (Zebra 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 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.

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

Follow these steps:
- Download and install latest version of Neodynamic ThermalLabel SDK for .NET
- Open Visual Studio 2005 / 2008 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

Code:

---

      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

Code:

---

  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 Class file and name it Product. After that paste the following code into it:
Visual Basic .NET

Code:
