I noticed that GridView in contentTemplate of PanelBar becomes visible during expending/collapsing animation.
It seems that sequence of events for onClick is as follows:
- show content (overlayed on top of panelbar)
- start animation
- animation completed
- start collapsing
- end collapsing
- hide the content
Question: Is it possible to make PanelBar show content in a sliding-exposing fashion?
UPDATE: THIS ONLY HAPPENS IN IE7. in FF everything slides down/up very nicely.
