问题 Can values or parameters be passed to a WPF user control? I am using MVVM pattern. <local:SampleUserControlView Forecolor="{Binding ForeColor}"/> where ForeColor is a property of Type Color or Brush in Viewmodel of the window hosting SampleUserControl View. By the way, should the property be of type Color or Brush? 回答1: yes you can pass by using dependency properties . You can create dependency property in your usercontrol of type what you want to pass. Below is a small example which will

问题 I just started learning Prism and trying to use it with MEF in a test WPF application. Based on "WPF Hands-On Lab: Get Started with the Prism Library" example in the Prism4 documentation, in a test WPF project I renamed MainWindow class to Shell . My Bootstrapper class has the following code (also based on the Lab example): class Bootstrapper : MefBootstrapper { protected override DependencyObject CreateShell() { return new Shell(); } protected override void InitializeShell() { Application

问题 I have written an MVVM app in WPF using MEF and Prism with three different regions. Code is across two modules, being discovered in the App.Config. I have all the navigation commands and structure working perfectly fine, but the one thing I am confused on is how to set the initial Views loaded into each region at app startup as there seems to be nowhere I can do this. Furthermore if I add something to the end of the MainViewModel constructor to explicitly navigate to screen set A, something

问题 I begin develop Prism 6 WPF view-switching application in MSVS 2015 Professional (russified). Below is my solution representation (I bag your pardon for Russian in my MSVS): Below is Bootstrepper of my application: class Bootstrapper : UnityBootstrapper { protected override DependencyObject CreateShell() { return Container.Resolve<MainWindow>(); } protected override void InitializeShell() { Application.Current.MainWindow.Show(); } } Both of my modules must be loaded with the application and

问题 We have an existing WPF application that uses PRISM (6.x) with Unity (3.5.x) for DI. We are going to be adding more functionality to this application and would like to start utilizing ReactiveUI for any new modules that we need to implement. We were hoping to minimize the learning curve and continue to utilize Unity and DI for our ViewModels; however, ReactiveUI uses Splat for View location and so far I have not been able to get my ReactiveUI module to actually display in a PRISM region

问题 Using Prism with WPF, I want to allow users to select from a repository which modules they'd like to use. Each module is essentially an add-on, and selecting a module to use would just move it into their 'Modules' folder of DLL to load. But, in trying to move DLLs around when the application is running, an error is thrown because the DLLs are in use at that moment. How can you get around this and allow users to Add/Remove modules at will? 回答1: Once an assembly is loaded into an AppDomain , it
