Selected row shifts to the bottom of the visible veiw area

Hi,

I am using a grid layout in a veiw to display certain data. When the visibleRowset is 20, a vertical scroll bar appears. Now when I scroll up and down for a few times and then select a row anywhere in the visible view it shifts to the bottom of the visible border of the view once the focus is set. Focus is basically Javascript code.

This means the scroll bar isnt able to retain its positon or the rows shift themselves.

Can you please help me as this is bugging me since a long time??

thanks and regards,
