Windows datagrid

[David Browne]

I have a bound datagrid on a windows form. One of the textbox columns in the grid is programatically modified. However, the datagrid does not recognize that the row itself has been edited and therefore the user cannot save the row.

QUESTION:
Can the row of a datagrid be programatically placed into edit mode such that the update method on the underlying datasource would function?

Thanks
