  Hello.
  
  I have installed the last Version of Component One 4-0-20183-338 for WinForms (Windows 10).
  
  I have a form with the Flexgrid and when I select cells from one to another by mouse, the event “BeforeEdit” fires many many times. The same situation happens when I use scroll in the flexgrid.

  Hi,

  this is the expected behavior: the “BeforeEdit” event has a misleading name: it is actually fired before the grid renders a cell. Dependening on the result of the event handler, the grid might render e.g. a drop down arrow for editable cells.

  If you want to check whether a cells is editable just before the user starts editing, handle the “StartEdit” event.

  Best regards

  Wolfgang

  Hello,

  Thanks for explanation Wolfgang.

  Wolfgang’s explanation is correct. You can use the “StartEdit” event to check whether a cell is editable just before the user starts editing.

  In the prevous version of the components, the event “BeforeEdit” fired ONLY in the certain selected cell.
  
  So the question: why this event fires for all another cells now?
