Hi Kilo,

You can use the same datasource to bind against multiple controls.

List<Employee> employees = new List<Employee>();
employees.Add(new Employee("Jim", "Seattle"));
employees.Add(new Employee("Bill", "New York"));
employees.Add(new Employee("Ann", "Florida"));

dataGridView1.DataSource = employees;
textBox1.DataBindings.Add("Text", employees, "Name");

Note, however, that you may need to use more suitable datasources than
simple lists.  Your best bet is to create a BindingSource of the list and
bind against this BindingSource.

List<Employee> employees = new List<Employee>();
employees.Add(new Employee("Jim", "Seattle"));
employees.Add(new Employee("Bill", "New York"));
employees.Add(new Employee("Ann", "Florida"));

BindingSource bs = new BindingSource(employees, "");
dataGridView1.DataSource = bs;
textBox1.DataBindings.Add("Text", bs, "Name");

When using databinding and you need to programmatically add and remove items
from a list, use a BindingList instead of List.  If you otherwise change
properties on bound objects, you may also need to use INotifyPropertyChanged
and fire off a PropertyChanged event.  

public class Employee : INotifyPropertyChanged
{
private string _name;
private string _address;
public string Name
{
   get { return _name; }
   set { _name = value; }
}

public string Address
{
   get { return _address; }
   set
   {
       if (_address != value)
       {
           _address = value;
           if (PropertyChanged != null)
               PropertyChanged(this, new
PropertyChangedEventArgs("Address"));
       }
   }
}

public Employee(string name, string address)
{
   Name = name;
   Address = address;
}

#region INotifyPropertyChanged Members

public event PropertyChangedEventHandler PropertyChanged;

#endregion
}
