Unfortunately, the OutlookBar doesn't quite meet my needs. I would like only the top item to be static, but the rest of the items should expand and collapse as happens in a PanelBar (i.e. the top item will always be visible to the user).
handling the PreviewCollapsed event, and it was preventing the collapse, but its child items were still disappearing. I just found out why: the collapse action is a trigger in the template. So now I've removed that, and the top item works the way I want.
So now I have another question. I got the default template
and have modified it do what I want. However, there are several resource names in the template that are not recognized (e.g. the "select" state has a BorderBrush resource named "RadPanelBar_BorderMiddleOver" and a Background resource named "RadPanelBar_TopItemBackgroundOver". If I understand their purpose correctly, I need them so that the theme is applied correctly. So what do I need to do to ensure that these resources get included?
Thanks for your help.
