How to Load Next Data to LongListSelector when Scrolling reaches at the end of the LongListSelector

Question

I need to call a function LoadNextData() on reaching at the end of the LongListSelector . I tried to Implement using the msdn twitter sample(https://code.msdn.microsoft.com/windowsapps/TwitterSearch-Windows-b7fc4e5e) with Incremental Loading but it uses
ItemRealized and ItemUnRealized  events. But when i used these events , they fires only when an item is added or removed from list what should i do?  Is there any alternative ? When i Scroll to the bottom these events are not fired . Is there any
way to solve this?

Hi Joel,
Based on my knowledge, the sample uses the ItemRealized event handler to check if the app need load more data.
if ((e.Container.Content as TwitterSearchResult).Equals(resultListBox.ItemsSource[resultListBox.ItemsSource.Count - _offsetKnob]))
Debug.WriteLine("Searching for {0}", _pageNumber);
_viewModel.LoadPage(_searchTerm, _pageNumber++);
The above code snippet ask for more if the app trigger certain conditions. I’ve tested the code sample you provided. It worked. If you still cannot make it working, please post more information for reproduction.
