hello Jin,
The solution u suggested is not for successive postback (i.e. its all about getting data at once from server), but my requirement is to get the internal gridview whenever a templatefielddata(assum templatefield to be a link button ) is being clicked. i.e. some parameter is passed to the server and based on that parameter the data to be fetched from server and to be displayed in respective child gridview,
so how can u guide me towards this requirement.....
