title: why BeforeRowLeave is not fired when leave the grid?
body: <p>I have a devexpress grid: each row has a checkbox and a text column, when I check the checkbox, the text column is updated. After the text column is updated, I would like to manual save the row to database, but I need to do some convert before I save it. So in beforeRowleave event, I write such convert data and save logic. </p>
  
  <p>My grid is on a form, there is another button on the form "Save Button". Now in my grid I have 3 rows of record, Let's call them R1, R2 and R3. </p>
  
  <p>I check the checkbox in R1, R2 and R3 one by one and then I click "Save Button". But it seems only R1 and R2 fires the beforeRowLeave event, R3 didn't fire this event. Does this because the gridview loses the focus?</p>
  
  <p>How could I fire a similar event for R3? Thanks a lot!</p>
