Supported by Silverlight for Windows PhoneCollapsedDo not display the element, and do not reserve space for it in layout.

Elements that have a Visibility value of Collapsed do not occupy any layout space. By default, elements are Visible.

WPF has a Visibility state of Hidden. Silverlight does not support the Hidden Visibility state. If you are migrating XAML UI definitions from WPF XAML, you will have to edit any cases that attempt to set a Visibility to Hidden.

Visibility in a Visual State

As part of defining visual states for a control, you will sometimes want to change the Visibility state of an object to Hidden. Visual states rely on animations. The property value type of UIElement.Visibility is Visibility, an enumeration. To animate values that are enumerations, you must use a DiscreteObjectKeyFrame.

The following XAML example shows a visual state that uses DiscreteObjectKeyFrame to change visibility.

<VisualState x:Name="Focused">
  <Storyboard>
    <ObjectAnimationUsingKeyFrames Storyboard.TargetName="FocusVisualElement" Storyboard.TargetProperty="Visibility" Duration="0">
      <DiscreteObjectKeyFrame KeyTime="0" Value="Visible"/>
    </ObjectAnimationUsingKeyFrames>
  </Storyboard>
</VisualState>
