Is there a way to be notified when your data is complete

I am trying to set a default indicator to show what row my table is sorted by (actually comes sorted this way from server) and I see the indicator appear and then disappear when the data arrives. Is there another way to have this indicator appear or is there some way I can make these calls after the table has been filled with that data? Or is there some other way to do this that won't result in having it reset when the data loads.

obj.setSortColumn(3);
obj.setSortDirection("ascending", 3);

I am worried, too.

My thinking
1)Enable the sort property like "Default Sort" before document.write(obj).

2)Handle the drawing completion event, and sort next.

for example, I want to display stock information from the beginning, not the order by Ticcar but order by volume or price(source XML is order by Ticcar) .

I'm sorry I had misunderstood it. Please forget above post.
I also want to learn the "complete event".
