  1. POComposite WPF (Prism) module resource data templates
    text
    copied!<p>Given that I have a shell application and a couple of separate module projects using Microsoft CompoisteWPF (Prism v2)...</p> <p>On receiving a command, a module creates a new ViewModel and adds it to a region through the region manager.</p> <pre><code>var viewModel = _container.Resolve&lt;IMyViewModel&gt;(); _regionManager.Regions[RegionNames.ShellMainRegion].Add(viewModel); </code></pre> <p>I thought that I could then create a resource dictionary within the module and set up a data template to display a view for the view model type that was loaded (see below xaml). But when the view model is added to the view, all I get is the view models namespace printed out.</p> <pre><code>&lt;ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:vm="clr-namespace:Modules.Module1.ViewModels" xmlns:vw="clr-namespace:Modules.Module1.Views" &gt; &lt;DataTemplate DataType="{x:Type vm:MyViewModel}"&gt; &lt;vw:MyView /&gt; &lt;/DataTemplate&gt; &lt;/ResourceDictionary&gt; </code></pre> <p>Edit:</p> <p>I can get it to work by adding to the App.xaml</p> <pre><code>&lt;Application.Resources&gt; &lt;ResourceDictionary.MergedDictionaries&gt; &lt;ResourceDictionary Source="pack://application:,,,/Module1;component/Module1Resources.xaml"/&gt; &lt;ResourceDictionary Source="pack://application:,,,/Module2;component/Module2Resources.xaml"/&gt; &lt;/ResourceDictionary.MergedDictionaries&gt; &lt;/Application.Resources&gt; </code></pre> <p>Which is fine, but it means that as new modules are created, the App.xaml file needs to be added to. What I'm looking for is a way for modules, as they load to dynamically add to the the Application.Resources. Is this possible?</p>
