I have a datagidview . when I make changes to the cells of datagridview and try to save it ,it is not getting saved when the cursor is in the same row. and it is getting saved when the cursor is in any other row. I used the following event but no use . i have to each time keep the cursor intentionally to some other row in order to save the change.

thanks in advance

private void dataGridView1_CurrentCellDirtyStateChanged(object sender, EventArgs e)
        {
            

            if (dataGridView1.IsCurrentCellDirty)
            {
                dataGridView1.CommitEdit(DataGridViewDataErrorContexts.Commit);
               
            }
        }
