title: How to do delete in DataGridView in winforms application
body: <p>From this <a href="http://social.msdn.microsoft.com/Forums/en-US/winformsdatacontrols/thread/75a312ed-de73-406a-bec5-64b62ab66925" rel="nofollow">MSDN Forum's answer by the moderator.</a> To delete a row, <strong>user can select the whole row, and then just use a "Delete" key to delete this row</strong>. I am confused by this sentence.
  Does it mean when I click the row I selected by mouse and hit "DEL" key on the keyboard?
  If it is, it just deleted the row from the grid but not saved it in the database at all.</p>
  
  <p>I doubt that the answer is wrong. How to delete the row in datagridview? I am using C# 4.0. </p>
