  Flexgrid 4.8.20241.657 in a winforms 4.8 program with one column with datatype = boolean.
  
  Shows checkboxes and lets them change.

  Public Class Form1
      Private Sub C1FlexGrid1_CellChecked(sender As Object, e As C1.Win.C1FlexGrid.RowColEventArgs) Handles C1FlexGrid1.CellChecked
          If e.Row Mod 2 = 0 Then
              e.Cancel = True
          End If
      End Sub
  End Class
  

  
  
  This does not do anything.
  
  How can I ignore the cellcheck, if i.e. there is an error or unwanted?
  
  Do I miss something?

  Regards

  Hi,

  you could handle the “ValidateEdit” event. Here, “e.Cancel” will work.

  Best regards

  Hello,

  The CellChecked event is triggered after the checkbox is checked or unchecked. Therefore, the Cancel property will not have any effect as the job has already been done.

  As per Wolfgang’s comment, you can use ValidateEdit event for this purpose. Please refer to the attached sample for implementation.
  
  Sample: FlexGrid_CancelCheck_VB.zip

  P.S.: Thank you, Wolfgang, for your input.
