Custom Event In C# WPF | Saatody | Amit Padhiyar

 Today I will talk about... How to create custom event in C# WPF. First, We need a class which can contains our properties and events. private double x = 0.0; public double X { set { x = value; OnValueChanged(EventArgs.Empty); } get { return x; } } Here, We have a property in A class. Where OnValueChanged() is protected event method within A class. Follow below code. public EventHandler ValueChanged; protected virtual void OnValueChanged(EventArgs e) { EventHandler handler = ValueChanged; if (handler != null) { handler(this, e); } } Now we invented new event which name is ValueChanged. You can use this event as normal event in other class(es). For example B class. Follow below code. BClass.ValueChanged += (sender, e) => { System.Console.WriteLine("X: " + BClass.X); }; This how we created ValueChanged custom event in C# WPF. Note: Always use 'event' keyword before EventHandler. This how com...
