  Hi Rizwan,

  You can disable the editing by adding the following check in the beginningEdit event of CustomGridEditor:

  _beginningEdit(grid: wjcGrid.FlexGrid, args: wjcGrid.CellRangeEventArgs) {
  
          if(args.cancel) {
              return;
          }
  ....
  }
  

  But this workaround can only be used if you have added the beginningEdit event before adding the CustomGridEditor. I have asked the dev team on whether they can provide another workaround. The internal tracking id of the case is 421641.

  Regards,

  Hi Ashwin,

  I have tried what you suggested, added the beginningEdit event before adding the CustomGridEditor column but its still opening. Though it works when i set e.cancel in my own beginningEdit handler too. Waiting for other workaround. Please update me on that as soon as its done. Thanks for your help.

  Hi Rizwan,

  I will update you as soon as I will hear from the dev team.

  Regarding your own beginningEdit event, you need to set e.cancel to true in your own beginningEdit event because that’s how the CustomGridEditor class will know that it needs to cancel the creation of the custom editor.

  Hi Rizwan,

  The dev team has provided a workaround using the selectionChanged event. In the selectionChanged event, if you wish to prevent the editing in the currently selected cell, then set that particular column as read-only. And, if the cell can be edited, then set that column back to editable again.

  You can use the isReadOnly property to change the read-only status of the Column.
