Make as many useful recordings as possible, because I like them very much and keep it up (Greetings!) 🙂

[@TalisBarbalho]

just found out this channel recently as I started to study wpf and c#. each video is like a gold mine. Thanks for sharing your knowledge and time

[@_buffer]

Thank you so much! I appreciate you a lot! :-)

[@DyslexicAnaboko]

I can't thank you enough! I have been working on the same stupid problem for hours and you just pointed out what I was missing all this time. I have a three tier Tree View control so it's getting very involved. All I wanted to do was make the UI update when the 2nd tier's check box was toggled to update the 3rd tier's list of check boxes. Your rudimentary Select all / Deselect all. I implemented the INotifyPropertyChanged in one of my classes, but I didn't realize you had to do it in all affected view models. That was the part I was missing! So incredibly not obvious. Your explanation was perfect, thank you!

[@_buffer]

I'm glad you found it useful! I hope the project goes well! :-)

[@TheUltraBlender]

Man, you just continue to amaze me. With a lot of tutorials i feel like they don't give you enough info or even worse, way too much. Then i end up going down the rabbithole and getting frustrated because i understand even less. And then there's your stuff giving just enough information to use the explained topic effectively but also having a few points to hook on if you want to dive deeper. You really got a talent for teaching, thanks for sharing and wish you all the best.

[@_buffer]

Wow! That means a lot! I really do appreciate that! It's stuff like this that makes keeps me motivated to make more and more videos! :-)

[@Ragnovlod]

This is a great tutorial. I appreciate how you talked about things that helps us follow along. You could do a short video on productivity - all those shortcuts you know and your speed at the keyboard - it really blows my mind. Thank you so much for putting this out here.

[@freestyle88]

Man, I've been trying for hours to get one stupid checkbox to update in the UI when a boolean property changes in the background... Could not find a decent explanation of how to implement OnPropertyChanged until I found this -- that [CallerMemberName] trick is definitely needed there if checking a boolean rather than a string... and it works like a champ. Thank you!

Heck yeah Matt! Well done! :-)

Espectacular, se entendió bastante, no alcanzo a entender del todo la parte final, pero fue extremadamente instructivo y útil. Gracias por tu tiempo invertido en estos videos, espero puedas aplicar un ejemplo con el contenido de un combobox dentro de un datagrid 😁🤩

[@semidash]

Thanks a million for the video!!! It really helped me to wrap my head aroud bindings. It would be great if you could do more videos on this topic

[@morek3766]

Great tutorial. Well explained. I was wondering when you’ll do a wpf tutorial that shows how to change pages with smooth transition without losing data for example, while also passing data to the new page. Thanks for sharing once more

[@_buffer]

I'd love to do a video on that!It's just matter of keeping the datacontext :-)

[@FiveNineO]

Great suggestion 👍

[@brandonkish3100]

Dude this is freaking awesome! Could you do a video explaining the MVVM model? I have struggled with it for a long time. I don't fully understand the relationships between the models, and then how to interface it with the code behind.

[@ContentPiano]

Thank you for the very clear explanation. Helped a lot!

[@GuildOfCalamity]

Awesome video. More WPF please! Would love to see business logic code driven from the UI binding, e.g. click a button and a webpage downloads (the button would be disabled until the download completed). I think this would be a good example to show async thread operations in the background updating the UI in the foreground.

[@_buffer]

That's a great idea! :-)

[@GuildOfCalamity]

@@_buffer You set a good speed during the tutorial and great editing; not too much detail, but not so vague that you don't know what's going on. Keep up the good work!

[@kpbarker]

Is it possible to bind dynamically? Creating labels dynamically along with a list of bool values. I'm trying to bind while looping through a for...loop to create a bunch of labels. The bound properties will be contained within a Dictionary.

[@antoinemoineau1037]

Thank you for this content ! The thing I can't wrap my head around is that binding doesn't seem to follow the traditional "The class is the blueprint and then you instantiate tangible objects and use those objects to do things". Here it looks like we are working directly with the blueprint. Is the object automatically instantiated by the UI ? How do you handle having multiple objects of the same class ? And how do you bind the same object to different places in the UI (for example a parameters view where you can modify settings on an object that is currently displayed in another view in the UI).

[@_buffer]

Great question! Feel free to join the Discord server! It's a lot easier to explain it over there :-)

[@kylerbriskey372]

Another amazing video! You explained so many things I was confused about over the past year of learning this stuff. Also, the databinding was great to learn too and imma practice this technique often! I have a couple questions. Q1) If I have different classes in my project, how do set multiple DataContexts. Like If I had PersonModel and AnimalModel in 2 different columns of a grid. Q2) That Debug.WriteLine() was new to me bug very cool. Does this only work in Debug mode? but once I build a release of my app, will that code not slow anything down, or do I have to go manually remove it from the code?

[@_buffer]

Thank you! I'm glad you found it informative! And in terms of setting multiple datacontexts for one class, that's not really recommended, if you're tryint to get data from a different ViewModel that would be bad architecture and I would suggest creating a service that both ViewModels could receive the same type of data from. This could be registered as a service using Dependency Injection for instance, which I recently made a video on. And as for the second question, that's correct, if you wanted the same functionality but when in release mode you could use `Trace.WriteLine`. :-)

[@cosmingugoasa5949]

Maaaann almost perfect video 😭 how would this setup change if I'm using a view model between the model and the view ?? The viewmodel would implement the INotify[...] but how does the link from the model to the view model work? Example : I crate a list of persons, I use this list to create the Observable Collection list, then one of the person changes ages (via business logic in the model class) is this change reflected to the ViewModel property to update the ui?
