Checkboxes on listview not checking

Hi

I'm new to Xamarin, this is my first app. Been doing C# for a few years now though. The problem I am having is this. I have an activity with a linear layout, containing two seperate linear layout. In one of the layouts I have a listview

now everything is appearing on the screen as intended, the layout is not the problem. The problem I am having is the checkboxes in the listview cells will not check, the cell turns orange when touched, the ItemClick event is fireing fine, I cannot however get the checkbox to check... if you know what I mean. The cell flashes orange and the visible checkbox just stays unchecked.

The code I am using so far

protected override void OnCreate(Bundle bundle) { base.OnCreate(bundle); SetContentView(Resource.Layout.ch_activate_screen);

        ServicePointManager.CertificatePolicy = new TrustAllCertificatePolicy();
        iPhone.Service1 ipx = new iPhone.Service1();

        DataTable retval = ipx.getRHIVRcut_Android(Intent.GetStringExtra("TRUSTRESID"));

        List<string> names = new List<string>();

        foreach (DataRow row in retval.Rows)
        {
            names.Add(row["name"].ToString());
        }


        DateTime nextdel = new DateTime(2099, 01, 01);
        foreach (DataRow row in retval.Rows)
        {
            if (Convert.ToDateTime(row["dateofdel"]) < nextdel)
            {
                nextdel = Convert.ToDateTime(row["dateofdel"]);
            }
        }


        string[] dates = ipx.getDates(nextdel.Day.ToString(), nextdel.Month.ToString(), nextdel.Year.ToString()).Split('|');

        Spinner spinner = FindViewById<Spinner>(Resource.Id.spinner1);

        ArrayAdapter sss = new ArrayAdapter(this, Android.Resource.Layout.SimpleSpinnerItem, dates);

        ArrayAdapter adapt = new ArrayAdapter<string>(this, Android.Resource.Layout.SimpleListItemMultipleChoice, names);

        ListView list = FindViewById<ListView>(Resource.Id.listView1);

        list.Adapter = adapt;
        spinner.Adapter = sss;

        list.ItemClick += list_ItemClick;

    }


    void list_ItemClick(object sender, AdapterView.ItemClickEventArgs e)
    {
        ListView list = (ListView)sender;

        if (list.IsItemChecked(e.Position))
        {
            list.SetItemChecked(e.Position, false);

        }
        else
        {
            list.SetItemChecked(e.Position, true);
        }

    }

There is a spinner on the page that contains delivery dates, this is working fine, its just the checkboxes in the listview cells. To be honest I wouldn't have thought you would need to do the ItemClicked event, I just put that in to try to set the value of the checkboxes manually. Its still not working though.

Any ideas would be greatly appreciated!

Thanks

Steve.
