The VisualTransition objects in Transitions are applied when the control transition between states that are defined in the VisualStateGroup.

Examples

The following example creates a simple ControlTemplate for a Button that contains one Grid. It also contains a VisualStateGroup called CommonStates, which defines the MouseOver and Normal states. The VisualStateGroup also has a VisualTransition that specifies that it takes one half second for the Grid to change from green to red when the user puts the mouse over the Button.

Run this sample

<ControlTemplate TargetType="Button">
  <Grid >
    <VisualStateManager.VisualStateGroups>
      <VisualStateGroup x:Name="CommonStates">

        <VisualStateGroup.Transitions>

          <!--Take one half second to trasition to the MouseOver state.-->
          <VisualTransition To="MouseOver" 
                              GeneratedDuration="0:0:0.5"/>
        </VisualStateGroup.Transitions>

        <VisualState x:Name="Normal" />

        <!--Change the SolidColorBrush, ButtonBrush, to red when the
            mouse is over the button.-->
        <VisualState x:Name="MouseOver">
          <Storyboard>
            <ColorAnimation Storyboard.TargetName="ButtonBrush" 
                            Storyboard.TargetProperty="Color" To="Red" />
          </Storyboard>
        </VisualState>
      </VisualStateGroup>
    </VisualStateManager.VisualStateGroups>
    <Grid.Background>
      <SolidColorBrush x:Name="ButtonBrush" Color="Green"/>
    </Grid.Background>
  </Grid>
</ControlTemplate>
