I'm looking to display a large dataset via a list view in GTK# and performance is an issue here. I'm currently using a TreeView backed with a ListStore, but adding all my data to the ListStore takes forever. Is there a list view widget of some sort in GTK that supports lazy loading of data? In Winforms, you can use the VirtualMode property of DataGridView to handle this, but I don't see anything of the sort for GTK.
