Remarks

You can specify the visual behavior of a control when it transitions between states by adding VisualTransition objects to the ControlTemplate. When you create a VisualTransition, you specify one or more of the following:

  • The time it takes for a transition between states to occur by setting the GeneratedDuration property.

  • Additional changes in the control's appearance that occur at the time of the transition by setting the Storyboard property.

  • When the VisualTransition is applied by setting the To and From properties.

Examples

The following example creates a VisualTransition that specifies that when the user moves the mouse away from the control, the control's border changes to blue, then to yellow, then to black in 1.5 seconds. For the entire example, see Customizing the Appearance of an Existing Control by Using a ControlTemplate.

<!--Take one and a half seconds to transition from the
    MouseOver state to the Normal state. 
    Have the SolidColorBrush, BorderBrush, fade to blue, 
    then to yellow, and then to black in that time.-->
<VisualTransition From="MouseOver" To="Normal" 
                      GeneratedDuration="0:0:1.5">
  <Storyboard>
    <ColorAnimationUsingKeyFrames
      Storyboard.TargetProperty="Color"
      Storyboard.TargetName="BorderBrush"
      FillBehavior="HoldEnd" >

      <ColorAnimationUsingKeyFrames.KeyFrames>

        <LinearColorKeyFrame Value="Blue" 
                             KeyTime="0:0:0.5" />
        <LinearColorKeyFrame Value="Yellow" 
                             KeyTime="0:0:1" />
        <LinearColorKeyFrame Value="Black" 
                             KeyTime="0:0:1.5" />
