Find all controls in WPF Window by type

Question

I\'m looking for a way to find all controls on Window by their type,

for example: find all TextBoxes, find all controls implementing specific i

Answer 1

For some reason, none of the answers posted here helped me to get all controls of given type contained in a given control in my MainWindow. I needed to find all menu items in one menu to iterate them. They were not all direct descendants of the menu, so i managed to collect only the first lilne of them using any of the code above. This extension method is my solution for the problem for anyone who will continue to read all the way down here.

public static void FindVisualChildren(this ICollection children, DependencyObject depObj) where T : DependencyObject
    {
        if (depObj != null)
        {
            var brethren = LogicalTreeHelper.GetChildren(depObj);
            var brethrenOfType = LogicalTreeHelper.GetChildren(depObj).OfType();
            foreach (var childOfType in brethrenOfType)
            {
                children.Add(childOfType);
            }

            foreach (var rawChild in brethren)
            {
                if (rawChild is DependencyObject)
                {
                    var child = rawChild as DependencyObject;
                    FindVisualChildren(children, child);
                }
            }
        }
    }

Hope it helps.
