LogicalTreeHelper.GetChildren Method

Definition

Namespace:

System.Windows

Assembly:

PresentationFramework.dll

Returns the collection of immediate child objects of the specified object by processing the logical tree.

Overloads

GetChildren(DependencyObject)	Returns the collection of immediate child objects of the specified object, by processing the logical tree.
GetChildren(FrameworkContentElement)	Returns the collection of immediate child objects of the specified FrameworkContentElement by processing the logical tree.
GetChildren(FrameworkElement)	Returns the collection of immediate child objects of the specified FrameworkElement by processing the logical tree.

GetChildren(DependencyObject)

Returns the collection of immediate child objects of the specified object, by processing the logical tree.

public:
 static System::Collections::IEnumerable ^ GetChildren(System::Windows::DependencyObject ^ current);

public static System.Collections.IEnumerable GetChildren (System.Windows.DependencyObject current);

static member GetChildren : System.Windows.DependencyObject -> System.Collections.IEnumerable

Public Shared Function GetChildren (current As DependencyObject) As IEnumerable

Parameters

current

DependencyObject

The object from which to start processing the logical tree. This is expected to be either a FrameworkElement or FrameworkContentElement.

Returns

IEnumerable

The enumerable collection of immediate child objects from the logical tree of the specified object.

Remarks

Use this signature and helper method primarily when you are unsure whether current is a FrameworkElement or FrameworkContentElement and are also unsure whether that object's class supports its own content model collection. If you can determine the type of the object you are querying, check the specific content property that you know exists on that type. For example, if you know that the object you are querying is an ItemsControl, check the Items property to get a strongly typed collection, which has collection interface support and is probably more useful than an enumerator.

GetChildren(FrameworkContentElement)

Returns the collection of immediate child objects of the specified FrameworkContentElement by processing the logical tree.

public:
 static System::Collections::IEnumerable ^ GetChildren(System::Windows::FrameworkContentElement ^ current);

public static System.Collections.IEnumerable GetChildren (System.Windows.FrameworkContentElement current);

static member GetChildren : System.Windows.FrameworkContentElement -> System.Collections.IEnumerable

Public Shared Function GetChildren (current As FrameworkContentElement) As IEnumerable

Parameters

current

FrameworkContentElement

The object from which to start processing the logical tree.

Returns

IEnumerable

The enumerable collection of immediate child objects starting from current in the logical tree.

GetChildren(FrameworkElement)

Returns the collection of immediate child objects of the specified FrameworkElement by processing the logical tree.

public:
 static System::Collections::IEnumerable ^ GetChildren(System::Windows::FrameworkElement ^ current);

public static System.Collections.IEnumerable GetChildren (System.Windows.FrameworkElement current);

static member GetChildren : System.Windows.FrameworkElement -> System.Collections.IEnumerable

Public Shared Function GetChildren (current As FrameworkElement) As IEnumerable

Parameters

current

FrameworkElement

The object from which to start processing the logical tree.

Returns

IEnumerable

The enumerable collection of immediate child objects starting from current in the logical tree.
