Cannot find some existing elements by FindAllDescendants()

[WangZhuoyuan0226]

From my desktop application, I can clearly see some elements which look like ListItem. But when I hover and click my mouse on the item, the Inspect can only display its parent panel. Also, when I want to call FindAllDescendants() and DrawHighlight() to list and display all the descendants in this window, I cannot get the list item that I can see in the app.

The code is here:
var elementArr = currentWindow.FindAllDescendants();
foreach( var element in elementArr){
element.DrawHighlight();
}

For secret policy, I can only draw a picture to illustrate my app problem.
