In this article I am going to explain you how to implement the cascading dropdownlist using AngularJs. This is a continuation to my previous article where I have blogged about how to populate the Dropdownlist from AngularJs. Hence I won’t be explaining the first part where we populate the Order Dropdownlist. You can get the details about that from link above.
Here we make use of ng-change event in AngularJs to call the function which in turn populate the CustomerList based on OrderID selected. ng-change event will fire when user changes the input in element and the new values to be committed to model.
