My name is Steven Robbins, and this is my allegedly technical blog.

These days I generally work in C# and SQL, but in the past I’ve developed in everything from Assembly Language (68000 and x86) through to VB. I’ve also done my time in the support/engineering side of IT, so I’m pretty much a geek through and through 🙂 I’m a firm believer that reading and “best practices” are no substitute for using your brain!

Yet for all its power, it is a little complex and that is my reason for launching into this blog series.

The rough outline for this series is as follows: To understand what databinding is and the service it provides us with, it is worth looking at how you wire-up a user-interface without using databinding.

Yesterday I was working on a small prototype, which I will be blogging about shortly, and ran across the common problem of my bindings not updating.

I also have a Dependency Property "DPB" on my View Model that is bound to B in code with a very simple binding (new Binding("A. Now I have three Text Boxes in my view: On first run, both A. Can anyone tell me why or how to change this behaviour? Dependency Object works with Freezables correctly, so next example does what you need.

Databinding is a fundamental part of the WPF, Silverlight and the Silverlight for Windows Phone 7 frameworks.

It is a powerful concept that once mastered allows you to write concise and elegant code.

So although I was firing an event that looked like INotify Property Changed.

Property Changed, I was actually just firing my own event with the same name 🙂 So there you have it, I’m an idiot 🙂 The moral of the story is, when your bindings aren’t working check the obvious: Hello there!
