Transcript from the "Challenge 7: Forms" Lesson

>> Lukas Ruebbelke: I think it's time to do a challenge. So I've already done the demonstration. What I would like everybody to do is in your widgets component, essentially I want to create a form with a save and cancel button, populate the form with your selected widget, and then using ngForm, add in some validation for editing the widget component.

[00:00:21] Now, if you use the item detail component as a reference, some of the stuff is going to be done for you. So you're just already going to have the buttons created. I would like you to hook them into the component class. So in other words, when I click Save or Cancel, I actually call a method on the class.
