Next we’re going to hook up the UI for our main application page through the DefaultViewModel collection.
A page of type ‘Items’ has a default View Model defined, and it is possible to hook up to a data source with only a few lines of code.
Once done, the page will render the items in the default template format. Of course,customization will likely take place from the default settings.
In this video, I will show you how to bind our data feeds to the DefaultViewModel[“Items”] element of our ItemsPage.
