c# - Prism for Silverlight: How to maintain views in a specific order inside a region

Question

I am creating sort of a "Navigation panel" (which is actually an ItemControl) for SL and using Regions to allow each module to add his link to the panel.

Problem is that modules loading is inconsistent and thus order of links in the panel can change according to modules loading order.

Restricting the modules order is out of the question.

Other feasible option is the order the region's Views Collection that is binded to the ItemControl, the problem is that ViewCollection is very limited, so ordering it is pretty hard.

Did I miss an option, do you have an idea?

Thanks Ariel

In Prism4 you just apply the ViewSortHintAttribute to your views:

[ViewSortHint("100")]
class FirstView : UserControl { }

[ViewSortHint("200")]
class SecondView : UserControl { }

The default sort comparer on the regions will pick up this attribute and sort the views accordingly. You can put any string into the attribute but I tend to use medium sized numbers that allow me to easily put a new view in between existing ones.
