Answer 1

Tried a lot of solutions recommended by the community. None really worked. Had to modify a bit. Here is what worked for me.

            List<LayoutPanel> panels = new List<LayoutPanel>();
        foreach (object rawChild in LogicalTreeHelper.GetChildren(dockManager))
        {
            if (rawChild is DependencyObject)
            {
                DependencyObject child = (DependencyObject)rawChild;
                if (child is LayoutPanel)
                {
                    panels.Add((LayoutPanel)child);
                }

                foreach (LayoutPanel childOfChild in FindLogicalChildren<LayoutPanel>(child))
                {
                    panels.Add(childOfChild);
                }
            }
        }
        var requiredPanel = panels.Where(t => t.Tag.ToString() == tagName).FirstOrDefault();

You could use the following FindVisualChildren method:

Find all controls in WPF Window by type

...and simply filter the results:

string tagName = "tagname";
IEnumerable<Ellipse> elements = FindVisualChildren<Ellipse>(this).Where(x => x.Tag != null && x.Tag.ToString() == tagName);
