Raise an event whenever a property’s value changed ?
-
Hi everybody. There is a property, it's named
ImageFullPath1public string ImageFullPath1 {get; set; }
I'm gonna fire an event whenever its value changed. I know I can beware of changing with
INotifyPropertyChanged, but I wanna do it with events. I don't know how I should do it. Could you please guide me? Thanks. -

I just hate the fact that it uses a string, however.

Use the alternative approach with the same result. You need a specifically named event with the default eventArgs the name must be YOURPROPERTYChanged . For best practice also supply and OnYOURPROPERTYChanged method as well. e.g.
private string _MyProperty;
public string MyProperty {
Get { return this._MyProperty; }
Set {
If (this._MyProperty != value){
this._MyProperty = value;
this.OnMyPropertyChanged(EventArgs.Empty);
}
}
}public virtual void OnMyPropertyChanged(EventArgs e){
if (this.MyPropertyChanged != null){
this.MyPropertyChanged(this, e);
}
}public EventHandler MyPropertyChanged;

I don't recall asking a question to which this was the answer.
