MT.D reload specific element

Hi,

I have a view that lists many pieces of information using MT.D I have a customised StyledStringElement as the element, if a user changes information in say row 100 by touching the element and selecting an option, I want to reload just that element so that the position on the screen is saved, if I reload all the elements the list goes to the top again, I have used

this.TableView.ScrollToRow(indexPath, UITableViewScrollPosition.Middle, false);

with limited success when reloading all the elements but it does not place me exactly on the right cell unless it was right in the middle of the screen.

thanks.

alex
