Answer 1

base on @Data-Base answer it will not work until make selection mode FullRow

  MyDataGridView.SelectionMode = DataGridViewSelectionMode.FullRowSelect;

but if you need to make it work in CellSelect Mode

 MyDataGridView.SelectionMode = DataGridViewSelectionMode.CellSelect;

 // for cell selection
 private void MyDataGridView_MouseDown(object sender, MouseEventArgs e)
 {
  if(e.Button == MouseButtons.Right)
    {
       var hit = MyDataGridView.HitTest(e.X, e.Y);
       MyDataGridView.ClearSelection();

       // cell selection
       MyDataGridView[hit.ColumnIndex,hit.RowIndex].Selected = true;
   }
}

private void DeleteRow_Click(object sender, EventArgs e)
{
   int rowToDelete = MyDataGridView.Rows.GetFirstRow(DataGridViewElementStates.Selected);
   MyDataGridView.Rows.RemoveAt(rowToDelete);
   MyDataGridView.ClearSelection();
}
