Displaying infinite Items in a Listbox control (XAML Windows Phone)

Question

I am making an E-Shopping app for Windows Phone platform. I'm stuck at a place where I need to display all the Search result Found after user input has been recorded. The issue arising is that , only the Products of the 1st Search Result page(as in the Website) get displayed. I need to load and display all the Products of the search term.

You can check the XAML CODE I'm using in the following link, and please tell what I need to add in it to display ALL the results instead of being limited to 1 page only.

Answer 1

You should use LongListSelector as ListBox depreciated.

Here is an explanation of How to create Infinite Scroll in a LongListSelector.

Basically you will be adding a definite number of items in LongListSelector as the user scrolls down to the end of the list.

Answer 2

Did you check your xml/json response that the items on the Page 2 is downloaded to your app? I think you are missing out some params in your web api call.

Because In general, a web api call doesnot provide all items at once, only we have to fetch in some pattern continiously.

Answer 3

You can achieve that using LongListSelector ItemRealized Event. Here is a detailed sample, I checked its perfectly working
