I have a XtraGrid binded to an objectset; after to have added several rows, not matter

how many, always that i press <Esc> (twice), WITH THE FOCUS in the NewInitRow

(FocusedRowHandle < 0), at the second time of pressing <Esc> the last

row recently added (row=rowcount-1) is deleted. After debugging, i found

the line of code problem:

private void advBandViewRGD_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
{
            if (e.KeyCode == Keys.Escape && advBandViewRGD.ActiveEditor == null)
            {

                //THE FOLLOWING LINE IS GUILTY:
                advBandViewRGD.CancelUpdateCurrentRow();
                advBandViewRGD.FocusedRowHandle = prevRowHandle;
            }

           ......

}

Why occurs this? Which is the solution?

Thanks in advance
