inotifypropertychanged

How do I raise PropertyChanged for SomeProperty in class B ? This example does not compile since PropertyChanged is not accessible this way... public class A : INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; } public class B : A { private object _someProperty; public object SomeProperty { get => _someProperty; set { _someProperty = value; PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(SomeProperty))) } } } Solution 1: You can use this RaisePropertyChangedExtension : public static class RaisePropertyChangedExtension { public static void

I have created WPF MVVM application, and set WPFToolkit DataGrid binding to DataTable so I want to know how to implement DataTable property to notify changed. Currently my code is like below. public DataTable Test { get { return this.testTable; } set { ... ... base.OnPropertyChanged("Test"); } } public void X() { this.Test.Add(...); // I suppose this line will call to getter first (this.Test = get Test) and then it will call add letter, this mean that setter scope will never fire. base.OnPropertyChanged("Test"); // my solution is here :) but I hope it has better ways. } Is it has another

I have this Base class : public abstract class WiresharkFile : BaseObservableObject, IDisposable { private string _fileName; private int _packets; private int _packetsSent; public string FileName { get { return _fileName; } set { _fileName = value; } } public int Packets { get { return _packets; } set { _packets = value; } } public int PacketsSent { get { return _packetsSent; } set { _packetsSent = value; OnPropertyChanged(); } } public void Dispose() { // Implemented insde inherit classes. } } BaseObservableObject: public class BaseObservableObject : INotifyPropertyChanged { public event

I have a custom object that I am trying to bind to a control. On that custom object I have implemented the INotifyPropertyChanged interface. I have successfully bound to my object and a property on that object. What I can't figure out is how to go from there. I've been working on this for 2 days now and I still cannot get it working. My assumption was that when I would change the property bound to the control that the value set in that property would then show up in the control. However, no matter how much I change the property, the UI is never updated beyond it's initial value. I have

I am working with some existing code and trying to figure out the advantage (if any) of using a string constant for the name of a property when implementing INotifyPropertyChanged interface. So for example doing this: /* * Why use this instead of string literal * in OnPropertyChanged below?? */ public const string CustomerIdPropertyName = "CustomerId"; private int _customerId; public int CustomerId { get { return _customerId; } set { if (_cusomterId != value) { _customerId = value; OnPropertyChanged(CustomerIdPropertyName); } } } Instead of this: private int _customerId; public int CustomerId

I want to add more functionality to a project I have that makes use a number of classes packaged in the NET Framework. These same classes provide a number of properties which can be quite useful adapting the functionality of my project, however one thing that these classes lack is Events. If each property had a appropriate event that would fire whenever the value of such property changed, I could then assign a event handler that would act based on those properties value. I made a sample case bellow to illustrate my goal in the most simpler way I could think off. Sample case: The System.Net
