How to get ListBox ItemsPanel in code behind

Question

I have a ListBox with an ItemsPanel

Answer 1

Try out following extension method:

var childStackPanels = FindVisualChildren(ThumbListBox);

Method itself:

public static IEnumerable FindVisualChildren(this DependencyObject depObj) where T : DependencyObject
{
    if (depObj != null)
    {
        for (int i = 0; i < VisualTreeHelper.GetChildrenCount(depObj); i++)
        {
            DependencyObject child = VisualTreeHelper.GetChild(depObj, i);
            var typedChild = child as T;
            if (typedChild != null)
            {
                yield return typedChild;
            }    

            foreach (T childOfChild in FindVisualChildren(child))
            {
                yield return childOfChild;
            }
        }
    }
}

PS: You can yourself extend it to check for specific control name so method would return single control instead of list.
