DBGRID CONTROL

I am using DBGRID control and Remote Data Control
in my application. There is no problem in filling
the control but after filling the first time
I click the dbgrid control the sequence of record
is changed i.e. the first record moves down and
the last record gets vanished. But It becomes okay
if i click the buttons on the remote data control.
But without using this method how to solve.
Please Help Me Out
