    I've been on a Hiatus from the defense/aerospace company I previously worked at (which did desktop/WPF applications for military aircraft), too do some web development, both frontend and backend. I'm going back too the aerospace company though, so this has been an amazing refresher on WPF, Styling, MVVM etc. I didn't forget it all, but after working in Typescript and react for the past 10 months I def needed this. Thanks Sean!

Maybe in a few months I'll have to watch this video hahaha

    Dear Sean! Great video as it is, but it would be nice to add unit tests to it. It would be interesting to see if you test only the domain layer, or the db layer and the views as well in a start to finish tutorial.

    • @SingletonSean
      @SingletonSean  2 года назад +4

      Hey DrSteve! I would certainly test the domain layer (as you suggested) and miiiight test the DB layer with an EF in memory database. On the MVVM side, I'd also test commands since they typically contain important application logic. I probably wouldn't test view models that hard since they're typically just made up of properties, but I'd test any view models that have other methods defined. Lastly, I haven't had much luck ever testing views.
      I haven't done my research yet, but I'd love to figure out how to do E2E testing on a WPF application. That would probably be the best way to confidently test views and view models.
      I place a lot of value on testing in personal projects, so it would be nice to bring that to projects on the channel (hopefully in a non-repetitive or boring way lol). Good suggestion!

    Hi Sean, congratulations on your channel, I've been looking for more in-depth explanations about MVVM for some time without success, until I found your channel.
    In all the examples I found on your channel, you do the MVVM navigation where the CurrentView is changed by calling the next View by the CurrentView itself.
    How to have a fixed Menu in MainView (or MainWindow) and that the CurrentView is called through it?
    And also how to have more than one View opened (not modal), because in your examples we always have a single View, the CurrentView?
    Thanks in advance!

    • @robertorinaldi4964
      @robertorinaldi4964 2 года назад

      I’ve been racking my brains all day, but I finally managed to solve the problem.
      I put the buttons in the MainWindow and the ContentControl in an area of the Grid (specific row/column in the grid). And in MainViewModel I created the Commands that fill that area of the grid with Views, making the buttons always available to change the View of that area.
      It worked, but if I got something wrong, correct me. Thanks.

    Hi good video so far, Sean!
    I've been reproducing it/learning from it for about two days now. I ran into a problem with the initial migration of the DB which starts at 2:41:40.
    My problem was this message:
    "Could not execute because the specified command or file was not found.
    Possible reasons for this include:
    * You misspelled a built-in dotnet command.
    * You intended to execute a .NET program, but dotnet-ef does not exist.
    * You intended to run a global tool, but a dotnet-prefixed executable with this name could not be found on the PATH."
    Which could only be solved by this command "dotnet tool install --global dotnet-ef".
    I wanted to share this with you in case someone runs into the same problem.

    - Running the WPF app in the background (as a system tray)
    - Get selected text from outside of the WPF program (so when the user selects a text on any program outside of the current program window, we can get listen to the event and get the text accordingly)
    - Registering a hotkey to run the program
    After I'm confident enough that those things possible, I want to learn more about it and watch some of your videos for reference. Especially the MVVM part.

    Can't the "Store" be another public property inside viewmodel?

    • @SingletonSean
      @SingletonSean  Год назад

      Hey Deivid, the Store technically could be a public property that the view directly binds to. However, binding to objects that don't implement INotifyPropertyChanged could result in memory leaks, so you'll want to implement that interface on the store.
      On the other hand, I typically prefer views to only bind directly to view model properties. This allows stores or any other infrastructure beyond the view model layer to change independently without breaking a binding on the view. It's also just nice for the view model to explicitly reflect the data required for the view in my opinion.

    drop down menu nuget package is not compatible with .net framework 4.6 , is there any other way?

    • @SingletonSean
      @SingletonSean  2 года назад

      Hey Sunil, you could copy the dropdown component code into your own project so that it's built with .NET framework: github.com/SingletonSean/wpf-ui-workshops/tree/master/DropdownMenuControl
      My bad for not being this component backwards compatible with .NET framework!

    I really love the tutorial, but I would prefer a shorter video that focuses on the topic. It is an MVVM pattern video. You focus on styling, templating and animations. But great tutorial tho.

      @@SingletonSean The RUclips prefix just made the code much longer and harder to read, I watched till 1 hour and couldnt keep up anymore because of too long names and the name differences are so little you sometimes miss it, next time try to find a much more shorter and simple names please. Its not the problem how long the video is, the problem is how long the names are (characters) so you cant keep up. Also please dont switch between tabs so fast its hard to keep up, for 1 hour of your video it took me 4 hours because I had to pause and look where I am and check the names if they are correct... You seem like you know a lot and its a great tutorial but its too complicated with the names and the speed of you switching between tabs, it makes it really hard to follow. Thank you for being nice and actually wanting to know what the problem is, respect and good luck to you!

    Hey Sean
    please could you help me with this issue
    i put the the logic for the Error and Status message in a class MessageViewModel
    MessageViewMode is instanced into the ViewModel
    now i try to consume that in the View, See code










    but a binding error is trown:
    ErrorMessageViewModel property not found on object of type MessageViewModel. Target TextBlock.DataContext
    Do you have any suggestion about it?
    Tanks very much for your response
    Regards

    • @SingletonSean
      @SingletonSean  Год назад

      Hi MGA! The issue is that the Grid and the TextBlock DataContext's bind to an ErrorMessageViewModel. If you remove the TextBlock's DataContext binding, all your bindings should work.
      The reason the TextBlock doesn't need a DataContext set is that the TextBlock already inherits the DataContext from the Grid. Since the TextBlock inherits the DataContext from the Grid, all bindings set on TextBlock properties will already point to the ErrorMessageViewModel. By setting the TextBlock DataContext again, the DataContext is attempting to bind to an ErrorMessageViewModel.ErrorMessageViewModel property, which of course doesn't exist.
      Let me know if this makes sense!

      the issue with the DataBinding at the TextBlock is fixed, but now appear three issues

      MessageViewModel RUclipsViewersDetailsViewModel RUclipsViewersDetails.DataContext Object RUclipsViewersDetailsViewModel property not found on object of type MessageViewModel.
      the issues are now, because the DataContext for RUclipsViewersView is ErrorMessageViewModel and no more the RUclipsViewersViewModel
      Do you have any suggestion for the issues?
