How to add a blank new row to WPF DataGrid automatically when user start editing current row

Question

I have a DataGrid bind with ObservableCollection<MydataObject> MyDatalist With all the default settings, if user change the focus from the DataGrid (e.g. clicked a button) while editing a cell, all the data showing in the DataGrid includes the one the user is editing are stored to MyDatalist, this is great, but the user need to hit "Tab" (while in the last cell) or "Enter" to create a new row.

I want the DataGrid to generate a new row automatically when user start editing any cell of the last row. I have tried the CurrentCellChanged event and I can have the new row automatically created by doing this:

void dataGrid1_CurrentCellChanged(object sender, EventArgs e)
{
     dataGrid1.CommitEdit(); 
}

However, with this implemented, if user change the focus from the DataGrid (e.g. clicked a button) while editing a cell, the one that the user is editing is not stored to MyDatalist, How can I have this feature back with the new row automatically added?

OK here is a Binding.UpdateSourceTrigger Property set this solved my problem:

Binding="{Binding Path=field1, UpdateSourceTrigger=PropertyChanged}"
