C # UWP Windows 10. In the class that implements INotifyPropertyChanged , there is a certain string to which the TextBlock is attached, everything works fine, but in one of the cases the string is assigned values ​​from another Task stream and the UI does not respond to changes.

Actually the question is how to make the UI update?

Tried to assign a value through the window Dispatcher - does not work.

UPD

The call to update a variable occurs in another thread:

 ... await Window.Current.Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, () => { Balance = Account.GetBalance(); }); ...

Setter Code

 public string Balance { get{...} set { _balance = value; NotifyPropertyChanged(); } }

Everything compiles, there are no errors, just when the code is executed in Task e - the UI does not update, the value changes according to the debugger.

  • @Serginio how does this apply to INotifyPropertyChanged and DataBinding ? Moreover, I do not have access to the form from the model, interaction in this direction is possible only through events - SYL
  • @SYL: I think the most direct. - VladD
  • @SYL: "I tried to assign a value through the Dispatcher window - does not work." What is this description, you are a programmer, I hope? Give the code, and instead of "not working" an exact description of the error (exception? Is not compiled?). And yes, if Task runs in another thread, then: (1) you have to ask yourself the question, why in another, is this correct? (2) if everything is correct, Dispatcher is the right way, most likely an error in your code. - VladD
  • This refers to the fact that you must cause a change in the flow of UI - Serginio
