How to: Make an Element Spin in Place

  • Article

This example shows how to make an element spin by using a RotateTransform and a DoubleAnimation.

The following example applies the RotateTransform to the RenderTransform property of the element. The example uses a DoubleAnimation to animate the Angle of the RotateTransform. To make the element spin in place, the example sets the RenderTransformOrigin property of the element to the point (0.5, 0.5).

Example

<!-- RotateAboutCenterExample.xaml
     This example shows how to make an element spin
     about its center. -->

                Storyboard.TargetProperty="(RotateTransform.Angle)"
                From="0.0" To="360" Duration="0:0:1" />
            </Storyboard>
          </BeginStoryboard>
