UIElement.Visibility Property


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

Namespace:   System.Windows
Assembly:  PresentationCore (in PresentationCore.dll)

[<LocalizabilityAttribute(LocalizationCategory.None, Readability = Readability.Unreadable)>]
member Visibility : Visibility with get, set

Property Value

Type: System.Windows.Visibility

A value of the enumeration. The default value is Visible.

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 .GTMT

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.

Metadata properties set to true


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.

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

End Sub 'PlayMedia
