I'm currently working on a navigation system. When a view is told be be shown, the navigation first looks if a control of that name already exists. If not, it creates the element, gives it a name, and adds it to the children of the root. If it does exist, it will simply enable and show that instead of creating a new one.

The problem is that I cannot find any children I've added.

control.Name = "Name";

Root.Children.Add(control);

Root.FindName("Name");

I cannot seem to find an object of that name. If I create the view in XAML and give it an x:Name attribute, FindName does work. Furthermore, when I look up all children, it says the source is null.

IEnumerable<object> c = Root.Children.OfType<object>();

To programatically register objects by name in the UI tree you have to call RegisterName().
That is what XAML parser does when it finds the x:Name attribute in a node.

Root.RegisterName("Name", control);
Root.Children.Add(control);
Control control = (Control)Root.FindName("Name");
