Dataview Rowfilter not working
 

Hi everyone, hope ur all.
After a long time i m posting here.
M in a problem abt. dataview.rowfilter. Matter is i have to create datareader from dataset, thats ok. The dataset is being filled up,no probs. After that i m applying rowfilter which is not working :

            da.Fill(s);

            s.Tables[0].DefaultView.RowFilter = " user_id=1 ";

                        

            dr = s.Tables[0].CreateDataReader();

No error is thrown, but its not working. I feel thrs sum logical error.Can anyone make it out.

Thanks all.
