Gets a value that indicates whether the TextBlock associated with this peer is understood by the user as interactive or as contributing to the logical structure of the UI.
Assembly: System.Windows (in System.Windows.dll)
In terms of strict definition of the control model, TextBlock is not a control in either Silverlight or WPF, because it derives from FrameworkElement, not Control. Silverlight and WPF both implement a behavior for this method whereby a TextBlock reports as true if the TextBlock is a declarative part of the UI, but returns false if the TextBlock is part of the template and control composition for another control. This method is called by IsControlElement.
