eXontrol Software - ExplorerTree ActiveX, NET Control

The BeforeCellEdit event notifies your application that the user starts editing a cell. Use the Edit method to programmatically edits a cell. Use the AllowEdit property to enable edit feature in the group. Use the BeforeCellEdit event to cancel editing cells or to change the edit's caption before it is displayed. Use the AfterCellEdit to change the cell's caption when the edit operation ends.

The following sample cancels editing cells on the first column only for the first group:

Private Sub ExplorerTree1_BeforeCellEdit(ByVal Group As EXPLORERTREELibCtl.IGroup, ByVal Item As EXPLORERTREELibCtl.HITEM, ByVal ColIndex As Long, Value As Variant, Cancel As Variant)
    If (Group.Index = 0) Then
        Cancel = ColIndex = 0
    End If
End Sub
