    <p>I am trying to delete rows from a listview. When I click delete, the row is removed. The ListView, however, fails to update. I have to click the back button and come back to see the item removed. Is there a way to refresh the page, after an item has been removed? Here is my code:</p> <pre><code>public class OrderHistoryAdapter : BaseAdapter { private List&lt;Order&gt; _orders; private Activity _context; public OrderHistoryAdapter(Activity context, List&lt;Order&gt; orders) { _context = context; _orders = orders; } public override View GetView(int position, View convertView, ViewGroup parent) { var item = _orders.ElementAt(position); var view = (convertView ?? this._context.LayoutInflater.Inflate( Resource.Layout.OrderHistoryDetailsRow, parent, false)) as RelativeLayout; TextView orderHistoryText = view.FindViewById&lt;TextView&gt;(Resource.Id.orderHistoryText); orderHistoryText.Text = ((Order)item).Date.ToShortDateString(); view.FindViewById&lt;TextView&gt;(Resource.Id.btnDeleteOrder).Click += delegate { OrderRepository orderRepo = new OrderRepository(); orderRepo.Delete(((Order)item).Id); //Item has been deleted, yet list fails to update NotifyDataSetChanged(); }; //Finally return the view return view; } public override int Count { get { return _orders.Count(); } } public Order GetOrder(int position) { return _orders.ElementAt(position); } public override Java.Lang.Object GetItem(int position) { return null; } public override long GetItemId(int position) { return position; } } </code></pre>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
