sir this is awesome tutorial I am working wpf only using mvvm now i am very much familiar prism this is nice and excellent sir thanks given to awesome tutorial
This webinar and prism, specifically, has really helped me to start building WPF apps. I just wasn’t getting all of the inotify, commands, and ViewModel communication requirements for WPF MVVM. Prism has definitely made that so much easier to understand and implement.
I want to apologize to everyone that commented and did not get a reply. I was not notified of any of your comments since I do not own this account. If you ask a question try tagging me or contacting me directly.
+Brian Lagunas Is there a validator implementation in prism 6? i'm currently using the one found at this link www.pluralsight.com/blog/software-development/async-validation-wpf-prism , but i wondered if there's a native implementation that handles that... I'm using WPF btw
+Gabriel Duarte No, not yet. We have been considering added something based on the article you linked to, but we just haven't got around to deciding if this is something we should add or not.
+Brian Lagunas Cool, i think it would be really great to have this built in the framework. In regards the article, i saw that you have courses in that same site. I have managed to get the solution to work, but the article says that were some extra stuff in the complete sample project, and the sample redirects to "www.pluralsight.com/blog". Do you know perhaps where it can be downloaded?
Best MVVM video content so far. I just started learning Prism based on this video. However, I encountered a problem at 44:09 , navigation between views. When I clicked ViewA-button, the ViewA content is empty. What I have tried: - checked my code multiple times - copy-paste all codes (App, Bootstrapper, UpdateEvent, ViewA, ViewB and MainWindow) from InfragisticsWebinarSimpleMVVMPrism in github. Still I don't know why clicking those buttons don't show anything. I appreciate any help to get good start with Prism ;) Using: Visual Studio Community 2017 Version 15.7.2 Prism.Core version 7.0.0.396 Prism.Unity version 6.3.0 Prism.Wpf version 6.3.0 Unity version 4.0.1
I am new to MVVM and Prism and your video helped me a lot. Thank you. What I would like to do is display a ViewModel at startup without having to press any buttons. Can you please advise me on how to change your PrismDemo to display ViewA without having to click on the button?
Brain, I know you've probably been asked this question ad nauseum but, do you have a time frame when a new Introduction to Prism v 6.0 will be available on Pluralsight? Really love to get a step by step full course on how to implement the newest version of Prism. I've been using Mvvm-light for such a long time that I fear jumping into Prism will become quite complicated. But I have a huge project that requires modules/plugins and Prism seems to be the best option. I've downloaded the examples from GitHub (which will be useful) but I'd love to watch a full course on the subject if possible.
Hi Brian, is there a way to tune UI when using assemblies modules (as on 1:14:00)? We will see that components only durin runtime. Is there a way to tune margins etc, and appearence - resources dictionary during design?
Great Video.Very helpful.I have a question about EvenAggregator. Doesn't it break the encapsulation,the only factor which differentiates events and delegates.Could you also explain how to unsubscribe an event using EvenAggregator.
+Brian Lagunas I am attempting to get this working (Prism 6), but I am not having any luck. It looks like when my application launches, the MainWindowViewModel is never constructed (IE, my commands are never initialized). How is it that your program is initializing the DelegateCommand without an empty constructor? I keep going through the video, but I cannot tell what mechanism is creating the MainWindowViewModel. Disregard. It looks like this happened because I changed the name of the MainWindow and the "Application.Current.MainWindow.Show();" in the Bootstrapper.cs did not like it.
can you tell me, why did you choose pluralsight for tutorials ? this project was open to everyone and the documentation was also enough for anyone to start. now people have to buy the tutorials. do you think that it is ethical ?
I am not here to prove myself to you. but i am no where near to a beginner. I also maintain a couple of open source projects. If you cant handle an open source project financially, then dont do it. hand over it to someone who can do that. none of the things you say make sense. I might as well take a project, dont do any tutorials or documentation and sell the tutorials. good idea though. so why did you take over the project then ? at microsoft they did everything for free. you could also say no to the project.
More PLEASE! This was extremely helpful and i can't wait for the full release of version 6. Is there anymore (maybe advanced) videos like this one on Prism v6?
Great Tutorial, i've been working on learning MVVM for a couple of weeks, and i think this will make it a bit easier using Prism 6.0. I have a small problem with the UpdateEvent parsing the message from ViewAViewModel to ViewBViewModel. It doesn't seem to work if I have not visited ViewB, I assume this is because the ViewBViewModel has not yet been instantiated until the view for it has been loaded at least once. Anybody got any ideas on this, I assume instantiating all viewmodels before they're needed is a bad idea, so how can you get default information into a viewmodel from other viewmodels before it's been instantiated?
Hey Brian, thanks for this. Really interesting video I have learnt a lot. A couple of questions if I may. I'm using version 6.2 of the Prism Core, I was following along in Visual Studio as you went through the examples the video but I cannot get the prismprop code snippet to work. It does not show up in the list and seems not to exist?! Has it been removed from v6.2.0? Also where you change the details of the prismprop code, it appears that after you change the first line to 'last updated' the get and set lines update automatically to reflect the change. I am not experiencing this. .. Is this a resharper feature or should I be able to get VS to do the same for me?
thanks for this tutorial what about prism for winrt or universal apps i can figure it out i am stack with prism for uwp please make us a tutorial prism for uwp thanks
Great video. Thank you! I exactly did what you've shown in the video however I'm unable to navigate to views from the MainWindow. The uri is being properly received in MainWindowViewModel in the Navigate method.Yet nothing happens on _regionManager.RequestNavigate("ContentRegion", uri); Any suggesions?
Venkat Raghavan Make sure you have registered your view for navigation with the container something like Container.RegisterType("SomeName"); ALso, you can get the sample code here: brianlagunas.com/infragistics-webinar-mvvm-made-simple-with-prism-sample-code/
+Brian Lagunas I am having the same problem, when your code runs InitalizeComponet() under MainWindow.cs it opens an instance of MainWindowViewModel, then it runs Bootstrapper. When my code runs is skips MainWindowViewModel and goes to Bootstrapper. do you have any ideas why this would happen?
+James Tays After doing some more debugging i found out that MainWindow has to be in the namespace WPFApplication1.Views you have to manually add it to the .Views for the ViewModelLocator to know to look for that.
+James Tays That's correct. You can read about the conventions here: brianlagunas.com/getting-started-prisms-new-viewmodellocator/ There are some small changes in Prism 6, such as the removal of the IView interface, but the rest is same.
+Brian Lagunas When I even copy everything from the working demo to a demo of my own return Container.Resolve(); is hit, but it never links the ViewModel - what I am missing here? Someone told me that ViewModelLocator only work with UserControls and not Windows. Have been racking my brain for 5hrs on this on part. Feel like I am crazy.. :(
