Prism for Silverlight : How to maintian views in specific order inside a region.

Question

Hi

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

Answer 1

This is not built into Prism regions, however it's easily implementable.

Damian Schenkelman has posted an extension method he created for adding a region to an index that seems to work pretty well. http://blogs.southworks.net/dschenkelman/2009/03/14/how-to-add-a-view-to-a-region-in-a-particular-index-with-prism-v2/

Hope this helps.

Well as the lack of answers counting. I have not found a solution with Prism.

Instead I've used MEF to solve this.

I will write a blog post on it and update this place holder.
