#109 – Navigating the Logical Tree in Code

You can use the LogicalTreeHelper.GetChildren method to traverse a logical tree and enumerate all of the objects in the tree.

Every element in a logical tree is a DependencyObject, so you pass a top-level object that derives from DependencyObject into the GetChildren method.  The method returns a collection of children of that object.

 // Enumerate each immediate child of main window.  (Does NOT descend down tree)
 foreach (Object obj in LogicalTreeHelper.GetChildren(mainWindow as DependencyObject))

You could extend this example and descend down the logical tree by calling GetChildren on the children returned from the first call.
