Try to bind into NotifyOnTargetUpdated - hope this is what you are looking for

<DataGrid Name="datagrid" AutoGenerateColumns="False" VirtualizingStackPanel.IsVirtualizing="True" VirtualizingStackPanel.VirtualizationMode="Recycling">
    <DataGrid.Columns>
        <DataGridTextColumn  Header="Title" Binding="{Binding Path=Name,NotifyOnTargetUpdated=True}" Width="300">
            <DataGridTextColumn.EditingElementStyle>
                <Style TargetType="{x:Type TextBox}">
                    <EventSetter Event="LostFocus" Handler="Qty_LostFocus" />
                    <EventSetter Event="TextChanged" Handler="TextBox_TextChanged" />
                    <EventSetter Event="Binding.TargetUpdated" Handler="DataGridTextColumn_TargetUpdated"></EventSetter>
                </Style>
            </DataGridTextColumn.EditingElementStyle>
        </DataGridTextColumn>
    </DataGrid.Columns>
</DataGrid>

I took the approach of having my row data objects inherit from IEditableObject. I handle the updated value in the EndEdit() interface method
