Storyboard.SetTargetProperty Method

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

Causes the specified Timeline to target the specified dependency property.

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

Syntax

'Declaration
Public Shared Sub SetTargetProperty ( _
    element As Timeline, _
    path As PropertyPath _
)

public static void SetTargetProperty(
    Timeline element,
    PropertyPath path
)

Parameters

Exceptions

Exception Condition
ArgumentNullException

One or more of the parameters is nulla null reference (Nothing in Visual Basic).

Remarks

This method sets the TargetProperty attached property on the specified object. For more information about how storyboard targeting works, see TargetProperty.

A property path uses a string syntax that allows you to target animations and animate properties that come from a template and are therefore inaccessible or out of scope. For details, see Property Path Syntax.

Examples

Run this sample

Private Sub Create_And_Run_Animation(ByVal sender As Object, ByVal e As EventArgs)
    ' Create a red rectangle that will be the target
    ' of the animation.
    Dim myRectangle As Rectangle = New Rectangle
    myRectangle.Width = 200
    myRectangle.Height = 200
    Dim myColor As Color = Color.FromArgb(255, 255, 0, 0)
    Dim myBrush As SolidColorBrush = New SolidColorBrush
    myBrush.Color = myColor
    myRectangle.Fill = myBrush
    ' Add the rectangle to the tree.
    LayoutRoot.Children.Add(myRectangle)
    ' Create a duration of 2 seconds.
    Dim duration As Duration = New Duration(TimeSpan.FromSeconds(2))
    ' Create two DoubleAnimations and set their properties.
    Dim myDoubleAnimation1 As DoubleAnimation = New DoubleAnimation
    Dim myDoubleAnimation2 As DoubleAnimation = New DoubleAnimation
    myDoubleAnimation1.Duration = duration
    myDoubleAnimation2.Duration = duration
    Dim sb As Storyboard = New Storyboard
    sb.Duration = duration
    sb.Children.Add(myDoubleAnimation1)
    sb.Children.Add(myDoubleAnimation2)
    Storyboard.SetTarget(myDoubleAnimation1, myRectangle)
    Storyboard.SetTarget(myDoubleAnimation2, myRectangle)
    ' Set the attached properties of Canvas.Left and Canvas.Top
    ' to be the target properties of the two respective DoubleAnimations
    Storyboard.SetTargetProperty(myDoubleAnimation1, New PropertyPath("(Canvas.Left)"))
    Storyboard.SetTargetProperty(myDoubleAnimation2, New PropertyPath("(Canvas.Top)"))
    myDoubleAnimation1.To = 200
    myDoubleAnimation2.To = 200
    ' Make the Storyboard a resource.
    LayoutRoot.Resources.Add("unique_id", sb)
    ' Begin the animation.
    sb.Begin()
End Sub
