Timeline.Completed Event

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Occurs when the Storyboard object has completed playing.

Namespace:  System.Windows.Media.Animation
Assembly:  System.Windows (in System.Windows.dll)

Syntax

'Declaration
Public Event Completed As EventHandler

public event EventHandler Completed

<timeline Completed="eventhandler"/>

Remarks

If this timeline is the root timeline of a timeline tree, it has completed playing after it reaches the end of its active period (which includes repeats) and all its children have reached the end of their active periods. If this Storyboard is a child Storyboard, it is considered to have completely finished playing when the root timeline of the timeline tree to which it belongs reaches the end of its active period and all its child timelines have finished playing.

Stopping a timeline does not trigger its completed event, but skipping it to its fill period does.

Examples

The following example fires the Completed event after a Storyboard ends.

Run this sample

<Canvas
  Width="200" Height="200"
  Background="White"
  x:Name="Page">
  <Canvas.Triggers>
    <EventTrigger RoutedEvent="Canvas.Loaded">
      <BeginStoryboard>
        <Storyboard x:Name="ColorStoryboard" Completed="onCompleted">

          <!-- Animate the background color of the canvas from red to green
               over 4 seconds. -->
          <ColorAnimation BeginTime="00:00:00" Storyboard.TargetName="Page" 
           Storyboard.TargetProperty="(Panel.Background).(SolidColorBrush.Color)"
           From="Red" To="Green" Duration="0:0:4" />

        </Storyboard>
      </BeginStoryboard>
    </EventTrigger>
  </Canvas.Triggers>
</Canvas>
