## Creating a Popup ## Creating a Popup
The following example shows how to define a <xref:System.Windows.Controls.Primitives.Popup> control that is the child element of a <xref:System.Windows.Controls.Button> control. Because a <xref:System.Windows.Controls.Button> can have only one child element, this example places the text for the <xref:System.Windows.Controls.Button> and the <xref:System.Windows.Controls.Primitives.Popup> controls in a <xref:System.Windows.Controls.StackPanel>. The content of the <xref:System.Windows.Controls.Primitives.Popup> appears in a <xref:System.Windows.Controls.TextBlock> control, which displays its text in a separate window that floats over the application window near the related <xref:System.Windows.Controls.Button> control.
The following example shows how to define a <xref:System.Windows.Controls.Primitives.Popup> control that is the child element of a <xref:System.Windows.Controls.Primitives.ToggleButton> control. Because a `ToggleButton` can have only one child element, this example places the text for the `ToggleButton` and the `Popup` controls in a <xref:System.Windows.Controls.StackPanel>. The content of the `Popup` is displayed in a separate window that floats over the application window near the related `ToggleButton` control.
