+> The <xref:System.Windows.FrameworkElement.FindName%2A> method only finds elements that are part of the XAML namescope. If you add an element to the object tree programmatically after XAML is loaded, the element's `Name` or `x:Name` value doesn't automatically register in the XAML namescope. To make a dynamically added element findable by name, call <xref:System.Windows.FrameworkElement.RegisterName%2A> on the XAML namescope (typically the page or window root) before adding the element to the parent container. For more information, see [XAML Namescopes](wpf-xaml-namescopes.md).

 Logical focus refers to the <xref:System.Windows.Input.FocusManager.FocusedElement%2A?displayProperty=nameWithType> in a focus scope.  There can be multiple elements that have logical focus in an application, but there may only be one element that has logical focus in a particular focus scope.
 
-A focus scope is a container element that keeps track of the <xref:System.Windows.Input.FocusManager.FocusedElement%2A> within its scope.  When focus leaves a focus scope, the focused element will lose keyboard focus but will retain logical focus.  When focus returns to the focus scope, the focused element will obtain keyboard focus.  This allows for keyboard focus to be changed between multiple focus scopes but insures that the focused element within the focus scope remains the focused element when focus returns.

 An element can be turned into a focus scope in Extensible Application Markup Language (XAML) by setting the <xref:System.Windows.Input.FocusManager> attached property <xref:System.Windows.Input.FocusManager.IsFocusScope%2A> to `true`, or in code by setting the attached property by using the <xref:System.Windows.Input.FocusManager.SetIsFocusScope%2A> method.
