Examples

The following example shows how to add content to a Popup control.

TextBlock textBlock = new TextBlock();
textBlock.Text = "Popup Text";
textBlock.Background = Brushes.Yellow;
myPopupWithText.Child = textBlock;
myStackPanel.Children.Add(myPopup);

Dim myPopupWithText As New Popup()
Dim textBlock As New TextBlock()
textBlock.Text = "Popup Text"
textBlock.Background = Brushes.Yellow
myPopupWithText.Child = textBlock
myStackPanel.Children.Add(myPopup)

<DockPanel>
  <Popup IsOpen="True">
    <TextBlock Background="Yellow">Popup Text</TextBlock>
  </Popup>
</DockPanel>

Remarks

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.
