UIElementCollection Class

Represents an ordered collection of UIElements.

Namespace: System.Windows.Controls
Assembly: PresentationFramework (in presentationframework.dll)
XML Namespace:

public class UIElementCollection : IList, ICollection, IEnumerable
public class UIElementCollection implements IList, ICollection, 
public class UIElementCollection implements IList, ICollection, 
You cannot use this managed class in XAML.

The Panel base class uses a UIElementCollection to represent its collection of child elements. Methods and properties defined by the UIElementCollection affect all objects derived from Panel and define a common feature-set for the manipulation of Panel child elements.

A UIElementCollection has affinity to its own context (class). You must access the collection from the context of the owning Panel.

The following example uses the Add method to add child content to a parent StackPanel. You do this by using the Children property, which is of type UIElementCollection. For the complete sample, see Using Elements Sample.

void AddButton(object sender, MouseButtonEventArgs e)
    btn = new Button();
    btn.Content = "New Button";
