Guidance on Two-Way Binding on a Model property

See original GitHub issue


Hello, I am just starting out with blazor and your Mvvm library is already helping me a lot getting on. I just have a question if you could explain how to best handle two-way bindings on properties that are bound from the model. For example i have a model and a viewmodel like below. How would i go best to integrate notification into that view model?

Cheers Simon

Code sample

public class Model 
    public string Name { get; set; }

public class ViewModel : ViewModelBase
    private Model _model;

    public string Name 
        get  => _model.Name; 
            _model.Name = value;



Are you using Blazor WASM or Blazor Server?

Balzor Server

Thank you very much for the quick response and the change. Exactly what i needed and working like a charm!

Ah I think i did not get that across correctly. I do not want the Model to notify on the ViewModel. The ViewModel would still invoke the notification itself but the changes should be reflected on the Model so that the Business logic can handle the requests.

So I want the Model to hold the state for the api client and the ViewModel for interaction with the component. I updated my code example a little so maybe it gets clearer. In the end I think I can do with what I have shown in the example if there is not a build in way to deal with it.

Would it still be possible to add [CallerMemberName] to the OnPropertyChanged() Method?
