Prism View loading in StockTrader sample

Question

I have been looking through the code and the pdf documentation and I can't find anything that indicates how the StockTrader sample application decides which view (PositionSummary or WatchList) should be displayed by default.

Can anyone explain how this is determined?

Answer 1

If I remember correctly, the stock trader RI uses its own custom behavior named AutoPopulateExportedViewsBehavior. This behavior is different from the one used by Prism as out of the box and is designed to work specifically with MEF. Along with the ViewExportAttribute it register the view in the container while also adding in to the corresponding region at start-up. You can find both of them in the StockTraderRI.Infrastructure project inside the Behaviors folder.

Edit: Maybe I misread the question. If you are asking how it's determined which view between the PositionSummary and WatchList views is shown first, there is no specific configuration for this. The order is related to what module is initialized first. If you were to move the PositionModule after the WatchModule in the bootstrapper, the WatchList would be the one being shown by default.
