Custom DataBinding


private CVObjectCollection objectsList;

public void Append()
{
object obj = Activator.CreateInstance(ObjectType, new object[] {true});
_currentIndex = (objectsList as IList).Add(obj);
(obj as IEditableObject).BeginEdit();
}

I have in CVDataSource too the method Save():


public void Save()
{
CVObject obj = (CVObject)listaObjetos[_currentIndex];
(obj as IEditableObject).EndEdit();
}


The Binding is working perfectly, but I would like of implement a custom save method to my CVObject.
Example:

In my forms I have two TextBoxes Control (txtCode, txtDescription) and two Buttons Control (btnNew, btnSave).

private void btnNew_Click(object sender, System.EventArgs e)
{
this.myDataSource.Append();
}

private void btnSave_Click(object sender, System.EventArgs e)
{
this.myDataSource.Save();
}

What I wanna to do is following:
First: When CVDataSource to call the Append() method, to create a new object and to grant to the TextBoxes new values, as such as, blank values.
Second: When CVDataSource to call the Save() method, to save new object updated to BD.

The problem: When I call the Append() method the object, it's added correctly to collection, but the binding controls do not receive the new object.
I searched in internet by google and too in msdn library but, I not found some implementation to .NET Framework 1.1 version. I readed about PropertyChanged but, it is only in Framework 2.0, and the others implementations that I found, say to handle a Custom PropertyChanged in each Business Class derived from CVObject, but I dont wanna to do thus. I would like of use the Business Class just to mapping and to centre anything in my Base Object (CVObject), including the Custom PropertyChanged...

Someone can help me?
