Answer 1

Try using the HitTest function in the MouseDown event of the grid:

void dgvFileList_MouseDown(object sender, MouseEventArgs e) {
  DataGridView.HitTestInfo hit = dgvFileList.HitTest(e.X, e.Y);
  if (hit.RowIndex < 0 | hit.ColumnIndex < 0) {
    dgvFileList.EndEdit();
  }
}

Clicking outside the DataGridView control would require hitting a focusable control.
