Yeah... You kind of onpoint but not quite... You are right about the nested grid. and i can only see my child grid based on the selection i make on the parent grid. Now.... once i select a row from the Parent grid.....it will automatically show me the child grid based on the selection

Now my point is... if i have five records on the parent grid and select one of the records.... i only want the selected row to show instead of all the other 4.... Currently its highlights the selected record. but i will like to make the other records invisible while another record is seleted....

I hope  i explained better this time around
