how to retrieve object on click of particular row in tableLayout in xamarin C#

i am trying to create a tablelayout,where data from service get binded to rows of table.Here i want these things to happen

1.)First row of tablelayout should be Default given(that is "Select item" in my case).

2.)Onclick of any particular row i should be able to retrieve that particular object value.

3.)to put red color divider between rows

below is my code used

 TableLayout tl = FindViewById<TableLayout>(Resource.Id.maintable);

            var client = new RestClient("http://sitemakong.net/");
            var request = new RestRequest("Service/HeadingSearch", Method.POST);
            request.RequestFormat = DataFormat.Json;
            List<TableHeading> tableItems = client.Execute<List<TableHeading>>(request).Data;
           int countValue = tableItems.Count;
            TableHeading Tablevalues = new TableHeading();

            for (int i = 0; i < countValue; i++)
            {
                tableItems[0] = new TableHeading { HeadingID = 1, Heading = "_select_", SubHeading = "Hi"};

                Tablevalues = tableItems[i];
                var Heading = Tablevalues.Heading;
                id = Heading;

                //Create a new row to be added.
                tr = new TableRow(this);

                tr.Id = i;
                int rowId = tr.Id;
                tr.SetTag(Resource.Id.rowId, tr);
                tv = new TextView(this);
                createView(tr, tv, id.ToString());
                tl.AddView(tr);
            }
        }

        //Method

        private void createView(TableRow tr, TextView t, String viewdata)
        {

            t.SetText(viewdata, TextView.BufferType.Editable);

            //You have to use Android.Graphics.Color not System.ConsoleColor;
            t.SetTextColor(Color.Blue);
            t.SetBackgroundColor(Color.Cyan);
            t.SetPadding(5, 0, 0, 0);

            tr.SetPadding(0, 1, 0, 1);
            tr.SetBackgroundColor(Color.Black);
                      tr.Clickable = true;
                  tr.AddView(t); // add TextView to row.


        }

        public void HandleClick(object sender, EventArgs e)
        {
            var clickedTableRow = sender as TableRow;
      //      string strval = clickedTableRow.gett;
            int s = clickedTableRow.Id;

            var tag = clickedTableRow.GetTag(s);


            //GET TEXT HERE
          //  Toast.MakeText(this, tag + " hi  string " + strval, ToastLength.Long).Show();

            Toast.MakeText(this, tag + " hi " + s, ToastLength.Long).Show();
        }

I am new to xamarin and c#.Any help appreciated.

   public void HandleClick(object sender, EventArgs e)
    {
        var clickedTableRow = sender as TableRow;
        int s = clickedTableRow.Id;

        // s is the index of the row, so just retrieve the matching object
        // from the data source
        var selected = tableItems[s];

    }

to create the "special" row at the start of your table, you could just create a dummy element at the start of your datasource

List<TableHeading> tableItems = client.Execute<List<TableHeading>>(request).Data;

// create a dummy TableHeading, insert it at the start of the list
tableItems.Insert(0, new TableHeading { .. set the appropriate properties here .. });

int countValue = tableItems.Count;

then let your for loop execute and build the table - you will need to remove the line tableItems[0] = ...
