Hide InsertItem While Editing in listview asp net c#

If you want to hide InsertItem while editing just use these three events

protected void lv_ItemEditing(object sender, ListViewEditEventArgs e)
{
     ListView lvSender = (ListView)sender;
     lvSender.InsertItemPosition = InsertItemPosition.None;
}
 
protected void lv_ItemUpdated(object sender, ListViewUpdatedEventArgs e)
{
      ListView lvSender = (ListView)sender;
      lvSender.InsertItemPosition = InsertItemPosition.FirstItem;
}
 
protected void lv_ItemCanceling(object sender, ListViewCancelEventArgs e)
{
     ListView lvSender = (ListView)sender;
     lvSender.InsertItemPosition = InsertItemPosition.FirstItem;
}

and then append this to list view

OnItemCanceling="lv_ItemCanceling" OnItemUpdated="lv_ItemUpdated" OnItemEditing="lv_ItemEditing"

Hope this helps
