As I’ve been learning WPF with C# over the past year (coming from a background of C and Java before that), my implementation of this has evolved a bit, and I thought I’d share the progression and my thoughts on why each subsequent implementation is an improvement.
After being shown this technique and using it for a while, I felt increasingly like something wasn’t quite right and there was room for improvement. First, the property changed args were being created at application startup, for every property, whether or not anyone ever set it.
Pedantically (though sometimes practically), this is not as efficient as it could be.
= value) before doing the setting or firing the event.
The idea here is to prevent spurious event firing and thus spurious event handling.
To counter those two issues, I added a base class from which models (and View Models, if they expose properties directly) should inherit.
If you don’t like a common ancestor like that, you could always implement this with an interface and a default behavior extension method on that interface, but I’m not a fan of extension methods for ‘extending’ your own code in your own assembly (extension methods just being syntactic sugar on free-floating static methods) What’s going on here is that we maintain a cache of Event Args.
In the first step, we eliminated some boilerplate, and now, we’ve added it back into the mix.
Instead of in our setter, it sits above our property.
You’ve eliminated two lines of code and a conditional from property setters.
Amortized over an application, this will make the code more readable, more succinct, and easier to reason about.
For instance, if you bound a XAML text box to a class property called “My Text”, the class containing My Text would implement INotify Property Changed.Tags: Adult Dating, affair dating, sex dating
