Hi Bonnie

There is some sample code in the original message.//DEFINE class Address

If you just create a new form with a textbox and define the Address class as show.

Thanks
Gary

public class Address {
public String Street, City, State, Zip;
public int Amount;

}

public class WinForm : System.Windows.Forms.Form
{
///
/// Required designer variable.
///
//Create Class Address property
private System.Windows.Forms.TextBox tbStreet;
public string Street;
.
.
.
private void InitializeComponent()
{
//Initialize Address object
this.tbStreet = new System.Windows.Forms.TextBox();
this.oAddress = new Address();


this.tbStreet.DataBindings.Add("Text", oAddress,"Street");
