Process Event Delete with Mouse in DataGridView control

[quangnd0003]

I have a event to Cancel Delete of user :

private void dataGridViewKV_UserDeletingRow(object sender, DataGridViewRowCancelEventArgs e)
        {    
            string maKV = e.Row.Cells[0].FormattedValue.ToString();
            string tenKV = e.Row.Cells[1].FormattedValue.ToString();
            string message = string.Format(
               "Are you sure want to delete {0} [{1}]?",
               tenKV,
               maKV);
            DialogResult result = MessageBox.Show(message, "Delete?", MessageBoxButtons.OKCancel);
            if (result == DialogResult.Cancel)
            {
                e.Cancel = true;
                MessageBox.Show("Cancelled Delete");
            }
        }

I added a contextmenustri p into DataGridView... When row header clicked by rightmouse, contextmenu is displayed!
Now, I want then choose Delete from ContextMenu, then dataGridViewKV_ UserDeletingRow () is called, or how to delete a row?

private void DeleteToolStripMenuItem_Click(object sender, EventArgs e)
        {        
          //  call method?
        }

let me know...Thanks a lot!
