I use code similar like this:

    Dim ItemEnum As PropertyGridItem
    
    'Adds a PropertyItemEnum item with a caption of "Enum" and an initial value of 2
    'This will cause the constraint with a value of 2 to be selected
    Set ItemEnum = Category.AddChildItem(PropertyItemEnum, "Enum", 2)
    
    'Adds some constraints along with a Data value
    ItemEnum.Constraints.Add "Windows 98", 1
    ItemEnum.Constraints.Add "Windows 2000", 2
    ItemEnum.Constraints.Add "Windows XP", 3

Now while ItemEnum is active, you can read the value of the selected item:

Debug.Print "Enum Item Value =" & ItemEnum.Value

So far so good. But how do i find this value later in the program?

The old VB method would be:

Value = cmbBox.ListIndex

to find the listindex of the currently selected item.

How do i find 'ListIndex' in PropertyGrid? lets say i selected Windows 2000, the listindex would be 2.

Same  ItemEnum.Value will work later.

How? I tried:

Set Itemx = AdvancedGrid.FindItem("Enum")
If Not (Itemx Is Nothing) Then
    Debug.Print Itemx.Constraints(Itemx.Value)
End If

But that gives an error?

Excuse my stupidity :)

Hi,

Your stupidity is forgiven Wink

Constraints collection isn't zero based, first item will start at 1 Confused
So if you would add constraint:
  • .Constraints. Add "First item", 0
  • .Constraints. Add "Second item", 1
  • .Constraints. Add "Third item", 2
and want to get the index of the first item, it will produce an error because there is no constraint with index 0  
In this case you have to set Item.value + 1
  • Me.wndPropertyGrid.FindItem(ITEM.ID or "Caption").Constraints(Me.wndPropertyGrid.FindItem(ITEM.ID or "Caption").Value + 1).Data (or index)
If you don't use successive numbers for the <Data> for the added constraints above doesn't work
  • .Constraints. Add "First item", 0
  • .Constraints. Add "Second item", 1
  • .Constraints. Add "Third item", 2
  • .Constraints. Add "Third item", 4
  • .Constraints. Add "Third item", 8

In this case you have to loop constraints and compare constraint, annoying thing to do (in my opinion...)

 
Best way is to start added constraint with <Data> = 1 and use successive numbers, this way you are able to use Item.Value to "find" selected constraint.
 
Hope this helps Wink
