New Post: Configure PropertyGrid programmatically?

I need to build a property grid for a set of properties that will be determined dynamically at run-time. I'm prototyping using this PropertyGrid class, and I've had some success so far, but I was curious if there was an existing guide for configuring it in a programmatic way. Most of the documentation relies on xaml or attributes, which assumes a more static setup for properties.

At the moment, I'm trying to figure out if there is a way to set the custom ItemsSource in C# code, but I'm sure I'll have more questions as I keep prototyping.
