      • I would have thought someone had already asked, but I couldn't find the anwer. I have tried: 1. deleting the datarow directly: dr.Delete(). That seems to work because it is removed from the listbox, but later when I update my database, the dr.RowState for that row is correct, DataRowState.Deleted, but I can't get the record key to delete it from the database because it has already been removed!

The tab control has a property for itemsize that has a height and width field. I want to set these values but for some reason they are read only so trying to do something like: tabcontrol.ItemSize.Height = 2 won't work. It would seem the obvious direct

      • Example: - listview with 20000 virtual items - RetrieveVirtualItem() feeds some dynamically created items - scroll to the end of the list - set VirtualListSize to 200 (via a button click for instance) You'll then crash internally with an ArgumentOutOfRangeException exception (here at index 200). Nothing helps to avoid this. Really odd. The crash happens somewhere in ListViewItemColl
