Avalon / WPF (RSS)
One of the cool things about dependency properties is that they allow other things to be dependent on them and notified of changes to them (hence their name). However, one thing that people will sometimes stumble upon is that they want to know about a

After our last installment, which was written many moons ago (literally), the only remaining thing left to do (apart from clean up the code a bit) was to implement the IScrollInfo.MakeVisible method. Somebody has requested that I address this, so I am

I like to think of the technique I am about to demonstrate as the Ramora pattern - it allows you to attach a chunk of logic to any existing element that you have. The RadialPanel example showed an example of storing information on an element using attached

One of the coolest features in Avalon is the property subsystem. While it might seem difficult for some that Avalon has a property system built on top of the normal CLR properties, the power that this system gives you is incredible and is part of why

One of the handy things that you can do with data binding in WPF is that you convert the data as you pull it from the data source. The mechanism for this is the IValueConverter interface. Let's say that you have a list of numbers representing positions

I just noticed that somebody asked an IScrollInfo question and I did not notice. I need to learn how to use the blogging software a little better :( The question was basically about when ScrollOwner is set and why there are so many duplicated properties

When we last left the application it had the appearance of something that could scroll, but exceptions were being thrown from unimplemented members left and right. This posting will help out with that. Let's look at the SetVerticalOffset method as the

At the end of the first part we have created a custom panel that implements IScrollInfo, but if you try to scroll we throw exceptions, and we cannot see the content. Since this is a Panel, we need to start seeing content so that we can scroll the content

Recently I invested the time to learn how to implement the IScrollInfo interface on a control in Avalon. This was an interesting learning experience, and since the existing documentation for this feature is not out in the wild yet, and I figure that people
