In Part 1, I introduced Dialog Boxes and showed the basics of how to create one and import it through a solution. In this post, we'll take a look at a few other features including passing data parameters into the dialog and adding event handlers on form load or on click of a button.

Back in July 2017, Microsoft deprecated the dialog process, and announced that they would be replaced with task flows. While I think task flows are great, they only let you interact with fields on a single entity. If you want to do something more advanced like working with fields from multiple entities or interfacing with data from an external web service, you cannot. However, there is a new Dialog Box component in the system that we can use!
