>Just to clarify, the grid is a readonly display of data. However the data in the grid needs to get updated when changes to the underlying data is made. The form is a two tab form, one showing a list of selected data and the other tab allowing you to edit a row from the grid on the first tab. You can also add and delete rows.

Then I guess it depends how the DataGrid itself is updated on changes. If it is completely repopulated then adding the 'footer' row should be more doable....
