Item changes all by its self:
In my example,
If you change the grid value and click away a message box will show.
But the value displayed in the property grid has now redisplayed the original value. Is this a bug? https://forum.codejock.com/uploads/20080909_124847_value.zip - uploads/20080909_124847_value.zip ------------- Product: Xtreme SuitePro (ActiveX) version 13.0.0 Platform: Windows XP (32bit) - SP 2 Language: Visual Basic 6.0 |

Hi,
No it isn't Mark.
Not in this event, suppose you would check the entered value and it wouldn't be right, you are able to cancel the change. So the value must be still the same as before changing otherwise you would have to check the old value itself. After this event the value changed event will fire and the value is changed into the entered value. just as you see in your sample when displaying a MessageBox.
Hope this helps

Hi Internally the control does store both values, but to the user they have typed into the control a value and it may be that I am displaying a message box that says are you sure you want to set this value, the user look back at what they have typed only to see it back to the original value while the msgbox is displayed. That can’t be correct. ------------- Product: Xtreme SuitePro (ActiveX) version 13.0.0 Platform: Windows XP (32bit) - SP 2 Language: Visual Basic 6.0 |

Hi Mark
Now I understand what you mean. If user types something and you display a messagebox, the original value is displayed again and you can't see what you entered. This is one for CJ to fix
If you really need this, you can use this workaround and in the meantime CJ can fix this
Private Sub pgPropertyGrid_AfterEdit(ByVal Item As XtremePropertyGrid.IPropertyGridItem, NewValue As String, Cancel As Boolean)
Dim oldVal As String
Dim newVal As String oldVal = Item.Value newVal = NewValue pgPropertyGrid.FindItem(Item.Caption).Value = NewValue Dim retval As VbMsgBoxResult
retval = MsgBox("Are you sure you want to change " & oldVal & " into " & newVal & "?", vbOKCancel) If retval = vbCancel Then Cancel = True pgPropertyGrid.FindItem(Item.Caption).Value = oldVal End If End Sub

Hi Mark,
It's nice to have a workaround if you are going to release your application yourself but and it's only temporary...
It will do nicely for now, but I expect CJ to fix this in next release

Hi,
AfterEdit don't know if you going to commit this change. Use ValueChanged even instead:
Private Sub pgPropertyGrid_ValueChanged(ByVal Item As XtremePropertyGrid.IPropertyGridItem) MsgBox "A Message" End Sub ------------- Oleg, Support Team CODEJOCK SOFTWARE SOLUTIONS |

Hi Oleg,
In value change event the value is already set to entered value and checking here I have to know old value and as it behaves now, the value is changed into old value (user doesn't know what value he/she has entered) The workaround I showed could easely be done by you in after edit event. It works OK but don't change value into old value only if cancel = true.
Thanks

Hi,
Yes, you are correct Oleg, it's unnecessary
 For the ones who will use this until Oleg fixes this:
Private Sub pgPropertyGrid_AfterEdit(ByVal Item As XtremePropertyGrid.IPropertyGridItem, NewValue As String, Cancel As Boolean)
Dim oldVal As String
oldVal = Item.Value
Item.Value = NewValue
Dim retval As VbMsgBoxResult
retval = MsgBox("Are you sure you want to change " & oldVal & " into " & newValue & "?", vbOKCancel) If retval = vbCancel Then Cancel = True Item.Value = oldVal End If End Sub
Thanks a lot
