title: c# Is there an event for datagridview's checkedbox
body: <p>i would like to know if there is an event for every time someone checks an datagridview's checkbox.</p>
  
  <p>My goal is to count how many rows are checked but i want the count to be refreshed every time the user checks, so that is why i'm am wondering if there is an event for each check the user you do. (Just like in the normal checkbox, checkBox_CheckedChanged)</p>
  
  <p>Thank you</p>
