RadListView insertitemtemplate still showing after insert

I have a pretty simple scenario using manual data operations with rad list view. I insert an item into my collection in the ItemInserting event, the listview shows the new item but the insertitemtemplate is still showing. Is my setup wrong? Do I have to manually hide the thing?

After you have inserted the new item, set the InsertItemPosition to None:

RadListView1.InsertItemPosition = RadListViewInsertItemPosition.None
