Question

I am builng an M-V-VM application with Dynamic Loading of modules at runtime.

Each of these Modules has a default view which individulally they show on the selected region when I go

_regionManager.Regions["BottomMenuRegion"].Add(
    Container.Resolve<AdminModuleView>(), "AdminView", true);

However, When the Next Module loads it overwrtites the previous loaded view.. How can I load more than one view into a region so that it creates a “Menu” displaying the default view? e.g

<ItemsControl cal:RegionManger.RegionName="BottomMenuRegion" />

looks like

Module1View Module2View Module3View Module4View etc

Thanking you in advance.

I managed to do this by creating a StackPanelRegion Adapter and Using the following XAML

 <StackPanel  Orientation="Horizontal"
            cal:RegionManager.RegionName="BottomMenuRegion" >

            <ItemsControl>
                <ItemsControl.ItemsPanel>
                    <ItemsPanelTemplate>
                        <Grid/>
                    </ItemsPanelTemplate>
                </ItemsControl.ItemsPanel>
            </ItemsControl>
        </StackPanel >

Region Adapter Code Here for those in the same situation

 public class StackPanelRegionAdapter : RegionAdapterBase<StackPanel>
    {
        public StackPanelRegionAdapter(IRegionBehaviorFactory behaviorFactory) :
            base(behaviorFactory)
        {
        }
        protected override void Adapt(Microsoft.Practices.Composite.Regions.IRegion region, StackPanel regionTarget)
        {
            region.Views.CollectionChanged += (s, e) =>
            {
                if (e.Action == System.Collections.Specialized.NotifyCollectionChangedAction.Add)
                    foreach (FrameworkElement element in e.NewItems)
                        regionTarget.Children.Add(element);
                //Handle remove event as well.. 
            };
        }

        protected override Microsoft.Practices.Composite.Regions.IRegion CreateRegion()
        {
            return new AllActiveRegion();
        }
    }
