Re: datarow...indexdoesnt change
DataTable dt = new DataTable();
You`re creating a new DataTable each time. You need to persist it somehow...
maybe put the table in cache and check to see if it exists before creating it.
Cheers,

Re: datarow...indexdoesnt change
Global in what sense?
The problem here is that you are not keeping your old DataTable; you are
creating a new one each time and adding a new row to that new table. You need
to keep the previous datatable and add rows to that one.
