UIElement..::.Visibility Property

Gets or sets the user interface (UI) visibility of this element. This is a dependency property.

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

Syntax

Visual Basic (Declaration)

<LocalizabilityAttribute(LocalizationCategory.None, Readability := Readability.Unreadable)> _
Public Property Visibility As Visibility

Visual Basic (Usage)

Dim instance As UIElement
Dim value As Visibility

value = instance.Visibility

instance.Visibility = value

[LocalizabilityAttribute(LocalizationCategory.None, Readability = Readability.Unreadable)]
public Visibility Visibility { get; set; }

Visual C++

[LocalizabilityAttribute(LocalizationCategory::None, Readability = Readability::Unreadable)]
public:
property Visibility Visibility {
    Visibility get ();
    void set (Visibility value);
}

JScript

public function get Visibility () : Visibility
public function set Visibility (value : Visibility)

XAML Attribute Usage

<object Visibility="Visibility" .../>

Property Value

Type: System.Windows..::.Visibility
A value of the enumeration. The default value is Visible.

Dependency Property Information

Identifier field	VisibilityProperty
Metadata properties set to true	None

Remarks

Setting this property affects the value of IsVisible, which in turn may raise the IsVisibleChanged event. However, IsVisible has other factors that influence it, for instance the visibility settings of parents that contain it.

Elements where Visibility is not Visible do not participate in input events (or commands), do not influence either the Measure or Arrange passes of layout, are not in a tab sequence, and will not be reported in hit testing.

When inherited by Window or its derived classes, Window redefines the default value of this property to be Collapsed. This has the effect of not running the Measure pass of layout on an initially created Window, and RenderSize returns (0,0). For details, see Window. Popup also redefines the default value to be Collapsed, with similar resulting behavior for Popup and its derived classes.

Examples

The following example implements a handler that references two different named buttons that are intended to be a mutually exclusive pair in the user interface. Prior to running the actual program logic associated with the button, the button itself is set to be Visibility..::.Hidden, and the other button in the pair is set to Visibility..::.Visible.

Visual Basic

Private Sub PlayMedia(ByVal sender As Object, ByVal args As MouseButtonEventArgs)
    pauseBTN.Visibility = System.Windows.Visibility.Visible
    playBTN.Visibility = System.Windows.Visibility.Collapsed

    media.SpeedRatio = 1.0
    media.Play()

End Sub 'PlayMedia

private void PlayMedia(object sender, MouseButtonEventArgs args)
{
    pauseBTN.Visibility = Visibility.Visible;
    playBTN.Visibility = Visibility.Collapsed;

    media.SpeedRatio = 1.0;
    media.Play();
}
