Cannot retrieve Native property

[JeL]

Hi,

WpfObject. Using Spy the only valid option for object identification I see seem to be 
Native Property
Header {Value Defined}

To get this value i use this code:

Set oDesc=Description.Create()
oDesc("classname").Value="DevComponents\.WpfDock\.DockWindow" 
Set linkCollection=WpfWindow("WindowName").WpfObject("devname:=DockWindowGroup").ChildObjects(oDesc) 
For i=0 to linkCollection.Count-1
'  1)  nativePropertyVal = linkCollection(i).Object.Header 'Use the native property in place 
  
  set nativePropertyVal = linkCollection(i).Object
    nativePropertyVal.GetValue("Header")
   
    msgbox nativePropertyVal.GetValue("Header")

Next



However instead of getting value that spy show, I always get {null}.

Can you advise if any additional setup required to get Native property or am I doing something wrong?

Resolved by adding ToString when requesting native property
nativePropertyVal = tabCollection(i).Object.Header.ToString() 'Use the native property in place
