我正在尝试通过Prism学习WPF，并使用现代UI模板.我在使用区域管理器时遇到问题，无法在集合中找到区域，但是视图已正确注入.

I am trying to learn WPF with Prism and using Modern UI Template. I have Problem with region Manager, unable to find the region in collections but the views are getting injected properly.

这是我在做什么

步骤A:外壳窗口

<mui:ModernWindow x:Class="SimpleAccounting.Shell" xmlns="schemas.microsoft/winfx/2006/xaml/presentation" xmlns:x="schemas.microsoft/winfx/2006/xaml" xmlns:mui="firstfloorsoftware/ModernUI" xmlns:prism="www.codeplex/prism" ContentSource="/PlaceHolders/AccountModulePlaceHolders/AccountListPlaceHolder.xaml" > <mui:ModernWindow.MenuLinkGroups> <mui:LinkGroup DisplayName="Accounts"> <mui:LinkGroup.Links> <mui:Link DisplayName="New Account" Source="/PlaceHolders/AccountModulePlaceHolders/NewAccountPlaceHolder.xaml"> </mui:Link> <mui:Link DisplayName="Available Accounts" Source="/PlaceHolders/AccountModulePlaceHolders/AccountListPlaceHolder.xaml" /> </mui:LinkGroup.Links> </mui:LinkGroup> </mui:ModernWindow.MenuLinkGroups> </mui:ModernWindow>

第2步:页面源或区域定义

Step 2 : Page Source or Region Definitions

第3步:我拥有具有以下功能的模块

Step 3 : I am having Module which have

public class SimpleAccountingModule : IModule { private readonly IRegionManager regionManager; private readonly IUnityContainer container; public SimpleAccountingModule(IRegionManager regionManager, IUnityContainer container) { this.regionManager = regionManager; this.container = container; } public void Initialize() { regionManager.RegisterViewWithRegion("AccountListPlaceHoldersRegion", typeof(Views.AccountList)); } }

第4步:运行应用程序完美无问题.

Step 4 : Run the application works perfect no issues.

步骤5:在步骤3中进行调试时，我的区域管理器计数始终为零，而当我尝试在其中查找元素时，找不到错误区域.但是，视图已正确注入.

Step 5: While debugging in Step 3 my region manager count is always zero, and when i am trying to find an element in it getting error region not found. However Views are getting injected properly.

推荐答案

克里希纳，

您似乎应该在外壳程序窗口中添加ContentControl并设置RegionManager.RegionName，这是我的工作:

It looks like that you should add ContentControl and set RegionManager.RegionName in the Shell Window, here is what I do:

参考:棱镜4.1

项目1: HelloWorldModule

Views \ AccountList.xaml:

SimpleAccountingModule.cs:

public class SimpleAccountingModule : IModule { private readonly IRegionManager regionManager; private readonly IUnityContainer container; public SimpleAccountingModule(IRegionManager regionManager, IUnityContainer container) { this.regionManager = regionManager; this.container = container; } public void Initialize() { regionManager.RegisterViewWithRegion("AccountListPlaceHoldersRegion", typeof(Views.AccountList)); } }

项目2: HelloWorld.Desktop

Shell.xaml:

Bootstrapper.cs:

class Bootstrapper : UnityBootstrapper { protected override DependencyObject CreateShell() { return this.Container.Resolve<Shell>(); } protected override void InitializeShell() { base.InitializeShell(); App.Current.MainWindow = (Window)this.Shell; App.Current.MainWindow.Show(); } protected override void ConfigureModuleCatalog() { base.ConfigureModuleCatalog(); ModuleCatalog moduleCatalog = (ModuleCatalog)this.ModuleCatalog; moduleCatalog.AddModule(typeof(HelloWorldModule.SimpleAccountingModule)); } }

MainWindow.cs:

class MainWindow { }

这是类似的问题:

#RegionManager空(不继承) compositewpf.codeplex/workitem/10276
