Hello Bill O'Neil,
RadToolBar currently cannot open from bottom to top which would be a requirement for a facebook-like interface. You can use RadMenu instead - the
ExpandDirection property can be used to control the subitem opening direction.
For any kind of dialogs you may choose between RadWindow, RadToolTip and RadDock. It depends on the actual implementation. If the dialogs should be separate aspx pages you can use RadWindow. Otherwise you can choose between RadToolTip and RadDock based on the desired appearance.
I hope this helps,
Albert
