I want to load more data when user scroll to bottom of LongListSelector or ScrollViewer (contain longlistselector). I have search some stackoverflow question but it's not solve my problem
Here is a good post about Detecting **LongListSelector’s scrolling to the bottom. You can have Reference from here Detecting WP8 LongListSelector’s end of scroll (stretching)
Try this Implementation for calling calss function:
var _list_compress = new WP8PullDetector()
_list_compress.Bind(LongListSelectorName);
_list_compress.Compression += _list_compress_Compression;
