在区域中加载模块默认视图以创建菜单 [英] Load Module Default Views In Region to Create Menu

问题描述

我正在构建一个M-V-VM应用程序，并在运行时动态加载模块.

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

这些模块中的每个模块都有一个默认视图，当我进入时，它们分别显示在所选区域上

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);

但是，当加载下一个模块时，它将覆盖先前加载的视图..如何将一个以上的视图加载到一个区域中，以便创建显示默认视图的菜单"?例如

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" />

看起来像

Module1View Module2View Module3View Module4View等

Module1View Module2View Module3View Module4View etc

先谢谢您.

推荐答案

我设法通过创建StackPanelRegion适配器并使用以下XAML做到了这一点

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 >

区域适配器代码在这里适用于相同情况的人

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();
        }
    }
