POhow can I bind Bing Pushpins from multiple models?
text
Body
copied!<p>I have the requirement in my WP7 application to display pushpins on a bing map from multiple data sources and I am not sure of the best way to do this.</p> <p>So for example it would be something like this, I receive from a web service a list of people, a list of buildings, a list of POIs etc. I would need to display these individually in their own views but also display them on a map with different images for each type.</p> <p>I am trying to use a MVVM approach so have a class for a Person, class for a building and so on, each one of these has a location. I then have an ObservableCollection for each of these types and so using data binding it is easy enough to do a View for each of these.</p> <p>At the moment I only have one ViewModel but my first thought is that I think I should really have one ViewModel per type. So PersonViewModel, BuildingViewModel here? However a Map View would then need to take information from each of these views and I am no sure how you bind a view to multiple ViewModels like this or even if that is sensible.</p> <p>MapItemsControl also only seems to be able to bind to one thing so how can I bind it to multiple different data sources like this? I thought I could create a simple pushpin class but that would then mean having the data for each type duplicated and I eventually want to be able to click on the pushpins to display the details for the pin so wanted to keep the types separate</p> <p>Any pointers on a way forward much appreciated </p>
