Namespace:  System.Windows.Controls
Assembly:  PresentationFramework (in PresentationFramework.dll)
XMLNS for XAML: http://schemas.microsoft.com/winfx/2006/xaml/presentation, http://schemas.microsoft.com/netfx/2007/xaml/presentation

member SelectionOpacity : float with get, set
<object SelectionOpacity="double" .../>

Property Value

Type: System.Double
The opacity of the SelectionBrush. The default is 0.4.

If you set the SelectionOpacity to 0, the SelectionBrush is transparent and is not visible. If you set the SelectionOpacity to 1.0 or greater, the SelectionBrush is opaque and the selected text is not visible.

The following example creates a PasswordBox and sets the SelectionBrush property to green and the SelectionOpacity property to 0.5.

<PasswordBox SelectionBrush="Green" SelectionOpacity="0.5" 
             Foreground="Red" CaretBrush="Red"/>

The preceding example produces output that is similar to the following illustration.
