Hi ! I used values changed event to identify if cell value is empty . But if cell value is empty and it looses its focus , values changed event does not get fired. It fires only if you types something. Now my problem id prevent user from keeping some cells empty . How to do that Help ! |

Hi,
Add items with default values. User knows what to enter (value or chars) and you don't have to check the empty fields. You only have to check if an item has been changed. ------------- Product: Xtreme SuitePro (ActiveX) version 15.0.2 Platform: Windows XP (32bit) - SP 2 Language: Visual Basic 6.0 Zero replies is not an option.... |

Hi,
Private Sub wndPropertyGridFiles_AfterEdit(ByVal Item As XtremePropertyGrid.IPropertyGridItem, NewValue As String, Cancel As Boolean)
If NewValue = Empty Then MsgBox "This field is required, cannot be empty" Cancel = False ' I would expect this to work but it isn't :( End If End Sub This event fires also when no value or same value is entered. But it should be selected again if cancel = false. I ask myself what the purpose of cancel in this event is  ------------- Product: Xtreme SuitePro (ActiveX) version 15.0.2 Platform: Windows XP (32bit) - SP 2 Language: Visual Basic 6.0 Zero replies is not an option.... |
