Hi Juan,
Generally speaking, for a collection, to support the general functionality
of data binding, such as sorting capabilities, change notification and
filtering, you need to implement the IBindingListView, the IBindingList,
the ICollection and the IEumerable interfaces.
..NET 2.0 provides the BindingSource class, which has implmented all the
above interfaces and serves as a powerful data source. You can use the
BindingSource as the data source in your project.

controls such as textboxes and checkboxes and radiobuttons, etc.
You can bind any property of the objects to the WinForms controls, such as
TextBox, CheckBox or RadioButton without implementing any interfaces.
However, to update the data source when the value of the control property
changes, you should specify the DataSourceUpdateMode parameter in the
ControlBindingsCollection.Add method. The following is a sample:
this.textBox1.DataBindings.Add("Text", myObject,
"Name",true,DataSourceUpdateMode.OnPropertyChanged);
On the other hand, to update the control property value when the value in
the data source changes, you should implement the INotifyPropertyChanged
interface for the object's class. The following is a sample:
class Person:INotifyPropertyChanged
{
private string name;
public string Name
{
get { return name; }
set
{
if (value != name)
{
name = value;
propertyChanged(this, new
PropertyChangedEventArgs("Name"));
}
}
}
private event PropertyChangedEventHandler propertyChanged;
#region INotifyPropertyChanged Members
event PropertyChangedEventHandler
INotifyPropertyChanged.PropertyChanged
{
add { propertyChanged += value; }
remove { propertyChanged -= value; }
}
#endregion
}
}

can drag and drop into Windows Forms.
If your components are defined by a project in the currently open solution,
they will automatically appear in the Toolbox, with no action required by
you. You can also manually populate the Toolbox with your custom components
by using the Choose Toolbox Items Dialog Box (Visual Studio), but the
Toolbox takes account of items in your solution's build outputs with all
the following characteristics:
a. Implements IComponent;
b. Does not have ToolboxItemAttribute set to false;
c. Does not have DesignTimeVisibleAttribute set to false.
For more information on "Automatically Populating the Toolbox with Custom
Components", you may refer to the following MSDN document:

Hope this helps.
If you have any question, please feel free to let me know.
Sincerely,
Linda Liu
