C# WPF - Global ScrollViewer Mode

I have made some custom attached properties that enable me to create a "pop out" effect on any control.

It animates the width and/or height when a boolean DependencyProperty is toggled.

Is there a good way to set all ScrollViewer's scrollbar visibility inside the control to hidden during this effect? You can see some ugly scrollbars appear during the animation.

I would rather not have to traverse the visual tree at the start of the animation, and then do it again when开发者_Go百科 the animation completes.

EDIT: Although an alternate solution would be nice, at this point I'd rather bind to a readonly attached property named IsAnimating to handle setting the scroll visibility.

Is there a global way to to this?

Instead of animating the width of the control itself, try fixing its width at the start of the animation and reparenting it into a grid, and animate the grid's width instead. The original visual wouldn't change size in its own little world, and no scroll bars would appear or change.
