I gave Items per request as 50 records. So 1st time you scroll the list has 50 Records,2nd time you scroll the list has 100 records and 3rd time you scroll the list has 150 records ..etc. I have total 4050 records are available.
But here problem is it starting at the beginning of the list instead of the next displayed records. i.e. when you scroll till the end and it loads next 50 records and jumps to first item of total loaded list instead pointing to the 51 record.
So how to start scroll from the next loaded list . i.e. 1st time you scroll will be at the start 1 Record, 2nd time scroll will be at the start of 51 record etc...
