changes in table <--> DataGrid

P: n/a
Hello,

I have a DataGrid(View) and a DataTable. The DataTable is displayed in the
DataGridView. The user is allowed to select some rows and then the following
snippet updates some values in the selected rows:

foreach (DataGridViewRow row in dataGridView.SelectedRows)
{
row.Cells["theColumnName1"].Value = someCalculatedValue1;
row.Cells["theColumnName2"].Value = someCalculatedValue2;
}

Later, the changed rows in the DataTable are supposed to be recovered by
GetChanges(). But, the last selected row never is included in the rows
returned by GetChanges(). However the last selected row in the DataGridView
has visibly been changed by the mentioned foreach loop.

I think this last row is not changed in the DataTable because the changes in
a DataGridViewRow are never 'committed' in some way before changes to another
DataGridViewRow are made.

I tried a few things (like selecting other another row after the foreach
loop, hoping this would 'commit' the changes in the last selected
DataGridViewRow), but nothing helped. Anyone got a clue? It seems to me this
should be pretty straightforward...

Thanks a lot!
