Splash Screen, async exec and other stuff

[Gerhard Kreuzer]

Hi,

 

ok, now I have mastered that so far.

 

My app cames up, showing a spash screen, a listbox reports the progress of an async running application composer, I use the RX framework for that.

After finishing the composition, the app navigates to a LoginView, after successful login, it will show the BreakingNewsView, this is the next step.

 

What I found out so far:

 

- RX is quite good, but not so easy to master. There is no documentation and only bad samples, exept the tutorials by LeeCampbell.

 

- To buid up a wizard, the first View, usually a Window needs the section with the 'BridgeViewModelBehavior', all other views making up the different stages of the wizard have to omit this section in the xaml-file. Otherwise, each time a view appears, a new ViewModel is created, which isn't useful in this situation. This cames up without any message, so you have to be really careful!

 

- Use only the line 'xmlns:n=http://nRoute/schemas/2010/xaml' to reference the nRoute framework, if you design the (raw) views with VS2010, otherwise you run into designer-errors which make work really hard.

 

- After overriding OnLoaded in a ViewModel, derived from 'NavigationViewModelBase', the code in OnLoaded was never called, issue reported to Rishi.

 

- Try to use a code file called Mapping, which holds all navigation and View-ViewModel mapping, maybe some day the app changes and updates within the VM code files can break the code for other versions using different technologies ...

 

- nRoute makes navigation really easy, I guess, its the best you can get today.

 

With best regards
