ListView Loading

Can anyone help me Improve the performance of the standard MS ListView Control.


I have an application which requires a sorted iconised/report view of data which can sometimes be several thousand items. Althougth the ListView copes with this amount of data once loaded each row takes longer and longer to be added (this is especially noticable once a few thousand items are bulk loaded.


I have tried turning off sorting until loaded and LockWindowUpdate until loaded, but I cannot improve the poor performance (the data has already been loaded into a treeview and is being added to the list in a similar fashion to Explorer).
