How to bind ListBox to a very large data set

Question

I want to display a very large number of items to my ListBox. So I use binding like this

listBox.ItemsSource = largeList;

My ListBox does use VirtualizingStackPanel, however, I see that it takes very long time to render on the screen.

Is there a more effective way to do this ?

Answer 1

I am not sure if there are realy big data you should display them to user

By the way you could trick it like this : Make a new timer , on tick event (every 5ms) add less than 5 items
