I'm been playing with the new extended UI controls and I like them very much.
I have found some bugs and have some suggestions though.
I'm running 1.7.0.2 on XP.
1. There are some drawing issues with the actions. At runtime, if I change the text, making it longer, the item doesn't resize. If I change the text to something shorter, part of the bottom border and right side border are shown, however, it does eventually invalidate and redraw, though I haven't figured out what causes that invalidation. At design time, it seems to like shortening text (it resizes items then), but not making the text longer.
2. If either the header text or the header detail text renders longer than width of the control, it just isn't shown. They also appear to get rendered under the collapse/expand button. It'd be nice to have an AutoEllipsis button like labels have and to not render under the button.
3. I'd be nice if the there was a declarative method to associate StrataCollapsibleContainers to the link manager (in addition to the code method). I think there might be a couple of ways. One would be to implement the link manager as a property provider (like the tooltip or error providers). However, if you wanted more than on set on a form at once, this could get confusing (though if you don't provide a DisplayName attribute, it provides the name of the object in the property grid). Another option might be to have a link manager property as part of the StrataCollapsibleContainer. When set it would then automatically add itself to that container.
4. It would also be nice if the link manager just had a mechanism to set which container was shown initially, with the rest hidden, rather than having to remember to set that up manually every time.
Great job. Look forward to the next release!
