Bonnie,

I found that when I press Save button in toolbar data is not saved.
To fix this I added the following lines to form Save() method:

if (ActiveControl != null && ActiveControl is DataGridTextBox)
  ((DataGrid)((DataGridTextBox)ActiveControl).Parent).EndEdit();

If current control is outside grid I think that data is still not refreshed.
How to implement refresh for every active control when Save button is pressed ?

DataGrid EndEdit() method contains your recommendation:

((CurrencyManager)BindingContext[
	DataSource, DataMember]).Refresh();

>Call it in your BizObject .Save() just before you pass the DataTable to the DataAccess .Save() method.
