Parameters

obj1

DependencyObject

The first object.

obj2

Returns

DependencyObject

The first element in the parent tree that is both an ancestor of obj1 and obj2, or null if no such element exists.

FindCommonAncestor<T>(T, T, Func<T,T>)

Finds the common ancestor of obj1 and obj2 using the given function to get the parent of each element.

public:
generic <typename T>
 where T : System::Windows::DependencyObject[System::Runtime::CompilerServices::Extension]
 static T FindCommonAncestor(T obj1, T obj2, Func<T, T> ^ parentEvaluator);

public static T FindCommonAncestor<T> (this T obj1, T obj2, Func<T,T> parentEvaluator) where T : System.Windows.DependencyObject;
