QUESTION
In v1 of my application, I am using an asynchronous REST service to load the contents of a ListView in Xamarin forms, with Prism binding the View and the ViewModel.
I want to enhance the GUI with some features that are implemented in a Xamarin.Forms Behavior, and this is my first attempt at merging this Syncfusion demo into my Prism Application.
My current code (v1) looks like this: (note the REST call
...ANSWER
Answered 2018-Oct-02 at 10:39We would like to let you know that while using prism, it is not neccessary to create new instance for ViewModel class as it will be already registered along with the MainPage in App.Xaml.cs. So in the Behavior class you can get the ViewModel instance from the SfListView’s BindingContext while expanding or collapsing the items[Accordion like view] in the ItemTapped event.
For more details, you can refer the below UG documentation.

For your assistance, we have attached the modified sample and you can download it from the below link.
Sample link: http://www.syncfusion.com/downloads/support/directtrac/216438/ze/SfListViewSample-1851048626
You can fetch and load items inside SFListView from the specified URL. As we haven’t got any specific REST services available at our end, we suggest you to follow the procedures given the below link to achieve your requirement.

You can load more items into the collection by fetching data from the online server. You can refer the below documentation link to know about the procedure to load more items on demand in SfListView.

Please let us know if you require further details.
