Finding children of children

Hello. So I have a root(Called CanvasContentHost, see the image, i highlighted it). Under this root there many children with the same name and same properties, I want the child called ItemsControl and its highlighted in the image. Under ItemsControl there many children with same properties(These Children are WPFObject("ContentPresenter", "", x) where x= 0, 1, ..., 13).  Under each child(WPFObject("ContentPresenter", "", x)),  I want to select a child called  WPFObject("ContentControl", "", 2), see the image for clarity. Under each of these children, i want to select a child WPFObject("Canvas", "", ), see image.I want to count the number of Children Under each of these children. For some there is 1 child and others there is 3.


NB in the properties Name is the only thing that make these objects unique and the Name : CanvasContentHost,  Name: WPFObject("ContentPresenter", "", x), Name: WPFObject("ContentControl", "", 2), etc


below is my code:


var canvas = Aliases.AutomationExpert.Root.root.SplitPane.MiddleWnd.PhysicalView.PartDiagramControl.CanvasContentHost;
var rack_inrackViewer = canvas.FindChild(['ClrClassName', 'ClrFullClassName', 'WPFControlOrdinalNo'], ['ItemsControl', 'System.Windows.Controls.ItemsControl', 1], 5);

var allSlots = rack_inrackViewer.FindAllChildren("Name", 'WPFObject("ContentControl", "", 2)', 5);


var canvasTwo = allSlots.FindAllChildren("Name", 'WPFObject("Canvas", "", 1)', 5);

for (let i in canvasTwo; i < canvasTwo.length; i++){

if (i.ChildrenCount=== 3){
Log.Message("slot" +" " + i +" " + "is an ethernet slot");
else {

Log.Message("slot" +" " + i +" " + "is not an ethernet slot");

    I suggest you read through FindAll Method. If you just want to count the number of children in a specific node, then you don't have to iterate through all parent-child (tree nodes).

  • rraghvani thank you for you answer. I have given more clarity to the question now. I have already used findAll and FindAllChildren Methods but it is not working. Seems as if it is not selecting everything

    Also read through Addressing Objects in WPF Applications.


    Here's an example that uses the FindAll method, and highlights only 5 buttons


    function FindButtons()
        // Open
        var browser = Sys.Browser("chrome");
        var page = browser.Page("");
        var main = page.Panel("belowtopnav").Panel(0).Panel("main");
        var buttons = main.FindAll("ObjectType", "Button", 1);
        Log.Message("Number of buttons in page " + buttons.length);
        for (var i = 0; i < 5; i++) {



    FindAll method only returns an array of the objects, and doesn't perform anything else.
