C# WPF Tutorial #13 - ObservableCollection with ListView

Learning how to use ObservableCollection as the ListView's Item source, allowing us to use a single collection in our code and have the UI update itself automatically when the list is updated!

Happy Coding!

🤩🤩 Yes!! This is what I wanted to know! You always present the core stuff concisely! It seems that I can apply this lesson to my toy project which has DataGrid with ItemSource. The logic and principle may be same with List. ☺☺ Thank you very much as always!! 😄😄

BEST Videos! Thank you. They really help!!

Love your videos. So far the clearest explanation of data binding, ObservableCollections, etc. that I have found.

In this exercise, is there a disadvantage to initializing the collection when it is declared (instead of in the constructor)?

private ObservableCollection<string> entries = new();

Great series of tutorials. Thank you! However, I wish you had delved deeper into the delete function. As it is, when you remove an item, it will remove the first item it finds that matches, not necessarily the item you chose. This behavior is different vs. the non-bound version of the code, which removes the item you actually selected, not just an item with a matching name.

Very nice playlist, but I have no clue how I would come up with the idea that "ItemsSource" needs something of type "ObservableCollection<>". This is the first video in this playlist in which it feels like I got "fish" instead of learning to "fish". Anyway, thank you for everything. 🖖

Thanks for the video. Really helpful. I have a question here we are using binding but we are taking text box entry (That we are adding on button click)from GUI i.e., It we are not running independently right. Please correct me if i am wrong.

Don't you think about to make a course for Udemy? I'm not english speaker but can understand and you make it so easy to learn the concepts.
Btw, thanks so much for this videos!

I am programing in React a lot and there we have useState hook. UseState automaticlly refresh your view when it has been changed. Obsevarble collection I understand works similar. Correct me if I think wrong.

I checked like 3 times that I did it exactly as you, but my ListView stays empty after manually adding items `Entries.Add("Test")` in the Constructor of the binding class.

observablecollection = collection + INotifyPropertyChanged?
