Creating a Knockout JS Grid With Cascading Dropdowns

KnockoutJS is my personal favorite of the ever-growing assortment of MV* (Model-View) JavaScript libraries dedicated to helping developers create applications with rich client-side functionality. As I showed in a previous post, it’s relatively easy to get a simple app up and running with Knockout. However, more sophisticated solutions require a deeper understanding of how Knockout works and the various extensions and utility tools it provides. This post offers a walk-through of a pretty common scenario that’s a bit of a step up from “Hello World”–how to create a Knockout grid with cascading dropdowns.
