FastObjectListView vs DataListView

[Frederik Grunta]

Hi there,

Simple question:

I have 4 lists which I would like to add quite a lot of information to. Say
100,000 rows or so. I never need to remove anything or edit anything from
these lists. Data trickles in - I don't have all of the information
immediately.

As data comes in, is it faster to let the DataListView add the objects, or to
use the FastObjectListView and call SetObjects()?

Sorry, I would just time the execution myself, but I'm not sure how to for
DataListView.

Cheers,

Frederik

If you want speed, you want a FastObjectListView.

For a normal ObjectListView (which is what DataListView actually is), the
speed of building a list is 1000-2000 rows per second, depending on the
machine and the number of columns. Building 100,000 rows will take 30 seconds
or more!

But with a FastObjectListView, it will "build" in less than one second for
millions of rows.

So, FastObjectListView with SetObjects() is definitely the way to go.
