Windows Forms Programming in C#

Data Binding

In Windows Forms development, there often comes a time when you need to populate a number of controls with data from a database or other data source. Recall our example from Chapter 12: Data Sets and Designer Support, which used a data set populated from a database. Whenever the data set was changed, such as when the user added a row or deleted a row, we had to repopulate the list boxes so that the display was kept in sync with the data:

void addRowMenuItem_Click(object sender, EventArgs e) {
  // Add a new typed row
					CustomerSet.CustomersRow row =
					this.customerSet1.Customers.NewCustomersRow();
  row.CustomerID = "SELLSB";
  ...
					this.customerSet1.Customers.AddCustomersRow(row);

  // Update list box
  PopulateListBox();
}
