Hi,
i have CustomListViews to select items, but on the next page also the option to move to another item.
Now, i want to update this single item. I use this function to find and update:
That works fine as long as the item is in the visible area (but in the background). When the item is outside the view i got the error
I understand the error, but i have no idea how to fix it (without loading all items again)?
Regards
Matthias
EDIT: I measured the time i need to fill all elements again. It is practically invisible - so i update the whole list... But if anyone has a good idea it would be great

Did you forget to call Activity.LoadLayout?
