/** @property */ public UIElement get_Child () /** @property */ public void set_Child (UIElement value)
Property ValueThe UIElement content of the Popup control. The default value is a null reference (Nothing in Visual Basic).
Content Model: The Child property is the only content property for the Popup control. A Popup can only have one UIElement as a child, but that child can contain complex embedded content. For example, the child can be a StackPanel that contains an Image, text, and other types of controls.
When content is added to a Popup control, the Popup control becomes the logical parent to the content. Similarly, the Popup content is considered to be the logical child of the Popup. The child content is not added to the visual tree that contains the Popup control. Instead, the child content is rendered in a separate window with its own visual tree when the IsOpen is set to true.
The following example shows how to add content to a Popup control.
<DockPanel> <Popup IsOpen="True"> <TextBlock Background="Yellow">Popup Text</TextBlock> </Popup> </DockPanel>
Popup myPopupWithText = new Popup(); TextBlock textBlock = new TextBlock(); textBlock.Text = "Popup Text"; textBlock.Background = Brushes.Yellow; myPopupWithText.Child = textBlock; myStackPanel.Children.Add(myPopup);
