Dear JS-Support,
is FindResource is supported ?, like :

Storyboard sb = this.FindResource("PlayAnimation") as Storyboard;

How to find resouces in e.g. <Page.Resources> </Page.Resources> or external resources ?

Thanks in advance,
BR,
Péter

1.) Is this a proper way /syntax ?:
var storyboard = (Storyboard)mainPage.Resources["PlayAnimation"];

New question:
2.) how to set the target ??, like:
Storyboard.SetTarget(storyboard, buttonDoubleAnimationSample);

please, confirm.
Thanks,
Péter
