Gets or sets the progress of animation play. This is a dependency property.
A Double value between 0 and 1 that represents the progress of animation play. 0 for the collapsed state, 1 for the expanded state.
When the DXExpander‘s expand state is changed, it plays the expand or collapse animation. Use the AnimationProgress property to obtain the current animation play progress. To obtain whether the DXExpander is collapsing or expanding, use the DXExpander.Collapsing and DXExpander.Expanding properties, respectively.
