open a viewcontroller on tableview cell is clicked

I Have the following viewcontroller with a tableview and a custom cell:

using System; using System.Drawing; using MonoTouch.Foundation; using MonoTouch.UIKit; using System.Linq; using System.Threading; using System.Data; using System.IO; using Mono.Data.Sqlite; using System.Collections.Generic; using Zurfers.Mobile.Core; using AlexTouch.MBProgressHUD; using System.Collections;

namespace Zurfers.Mobile.iOS { public partial class iPhoneHotelSearchViewController : UIViewController {

    MBProgressHUD hud;

    public string Destination {
        get;
        set;
    }

    public DateTime CheckInDate {
        get;
        set;
    }

    public DateTime CheckOutDate {
        get;
        set;
    }

    public int Rooms {
        get;
        set;
    }   

    public iPhoneHotelSearchViewController (IntPtr handle) : base (handle)
    {

    }

    public override void ViewDidLoad ()
    {
        base.ViewDidLoad ();

        hud = new MBProgressHUD(this.View);
        hud.Mode = MBProgressHUDMode.Indeterminate;
        hud.LabelText = "Loading...";
        hud.DetailsLabelText = "Searching Hotel";
        this.View.AddSubview(hud);
        hud.Show(true);

    }

    public override void ViewDidAppear (bool animated) {
        base.ViewDidAppear (animated);
        SearchHotel ();

    }

    public void SearchHotel (){

        Hotel hotel = new Hotel();
        var distribution = new HotelDistribution[]{new HotelDistribution(){ Adults = 1, Children = 0, ChildrenAges = new int[0]} };
        var items = hotel.SearchHotels(Convert.ToDateTime("2013-08-08"),Convert.ToDateTime("2013-09-09 "),"(MIA)", distribution,"","","",0);


        List<DtoHotelinformation> data = new List<DtoHotelinformation>();

        foreach (var item in items)
        {
            DtoHotelinformation DtoHotelinformation = new DtoHotelinformation();
            DtoHotelinformation.code  = item.Code.ToString();
            DtoHotelinformation.price  = item.Price.ToString();
            DtoHotelinformation.title =  item.Name.ToString().ToTitleCase();
            DtoHotelinformation.subtitle = item.Address.ToString();
            DtoHotelinformation.rating  = item.Rating.ToString();
            DtoHotelinformation.imageUlr = item.ImageUrl;

            data.Add(DtoHotelinformation);
        }

        hud.Hide(true);
        hud.RemoveFromSuperview();
        HotelSearchTable.Source = new HotelTableSource(data.ToArray());
        HotelSearchTable.ReloadData();

    }

    partial void GoBack (MonoTouch.Foundation.NSObject sender)
    {
        DismissViewController(true, null);
    }
}

} Now the table source

using System; using MonoTouch.Foundation; using MonoTouch.UIKit;

namespace Zurfers.Mobile.iOS { public class HotelTableSource : UITableViewSource {

    DtoHotelinformation[] tableItems;
    NSString cellIdentifier = new NSString("TableCell");



    public HotelTableSource (DtoHotelinformation[] items)
    {
        tableItems = items;
    }
    public override int RowsInSection (UITableView tableview, int section)
    {
        return tableItems.Length;
    }

    public override void RowSelected (UITableView tableView, NSIndexPath indexPath)
    {
        //WHAT TO DO HERE

        tableView.DeselectRow (indexPath, true); // normal iOS behaviour is to remove the blue highlight
    }

    public override UITableViewCell GetCell (UITableView tableView, MonoTouch.Foundation.NSIndexPath indexPath)
    {
        CustomCell cell = tableView.DequeueReusableCell(cellIdentifier) as CustomCell;

        if (cell == null)
            cell = new CustomCell(cellIdentifier);
        cell.UpdateCell(tableItems[indexPath.Row].title, tableItems[indexPath.Row].subtitle, tableItems[indexPath.Row].price,
                        tableItems[indexPath.Row].imageUlr, tableItems[indexPath.Row].rating );
        return cell;

    }

    public override float GetHeightForRow(UITableView tableView, NSIndexPath indexPath)
    {
        return 70;
    }
}

}

Finally the customcell code:

using System; using System.Drawing; using MonoTouch.Foundation; using MonoTouch.UIKit; using MonoTouch.Dialog.Utilities;

namespace Zurfers.Mobile.iOS { public class CustomCell : UITableViewCell, IImageUpdated { UILabel headingLabel, subheadingLabel, priceLabel; UIImageView imageService; UIImageView star, star2, star3, star4, star5; public CustomCell (NSString cellId) : base (UITableViewCellStyle.Default, cellId) { imageService = new UIImageView(); star = new UIImageView(); star2 = new UIImageView(); star3 = new UIImageView(); star4 = new UIImageView(); star5 = new UIImageView(); headingLabel = new UILabel(){ Font = UIFont.FromName("Verdana-Bold", 14f), BackgroundColor = UIColor.Clear, TextColor = UIColor.FromRGB(241, 241, 211) }; subheadingLabel = new UILabel(){ Font = UIFont.FromName("Verdana-Bold", 8f), TextColor = UIColor.FromRGB(255, 255, 255), BackgroundColor = UIColor.Clear }; priceLabel = new UILabel(){ Font = UIFont.FromName("Verdana", 14f), TextColor = UIColor.FromRGB(241, 241, 211), BackgroundColor = UIColor.Clear };

        AddSubview(imageService);
        AddSubview(headingLabel);
        AddSubview(subheadingLabel);
        AddSubview(priceLabel);
        AddSubview(star);
        AddSubview(star2);
        AddSubview(star3);
        AddSubview(star4);
        AddSubview(star5);

    }

    public void UpdateCell (string title, string subtitle, string price, string imageUlr, string rating )
    {
        if (imageUlr != null) {
            var u = new Uri(imageUlr);
            ImageLoader MyLoader= new ImageLoader(50,50);
            imageService.Image = MyLoader.RequestImage(u,this);

        } else {
            imageService.Image = UIImage.FromFile("generic_no_image_tiny.jpg");
        }


        headingLabel.Text = title;
        subheadingLabel.Text = subtitle;
        if (subtitle.Length > 40) {
            subheadingLabel.LineBreakMode = UILineBreakMode.WordWrap;
            subheadingLabel.Lines = 0;
        }

        switch (rating) {
            case "T":
                star.Image = UIImage.FromFile("ZurfersMovil-Stars.png");
                star2.Image = UIImage.FromFile("ZurfersMovil-Stars.png");
                break;
            case "S":
                star.Image = UIImage.FromFile("ZurfersMovil-Stars.png");
                star2.Image = UIImage.FromFile("ZurfersMovil-Stars.png");
                star3.Image = UIImage.FromFile("ZurfersMovil-Stars.png");
                break;
            case "F":
                star.Image = UIImage.FromFile("ZurfersMovil-Stars.png");
                star2.Image = UIImage.FromFile("ZurfersMovil-Stars.png");
                star3.Image = UIImage.FromFile("ZurfersMovil-Stars.png");
                star4.Image = UIImage.FromFile("ZurfersMovil-Stars.png");
                break;
            case "L":
                star.Image = UIImage.FromFile("ZurfersMovil-Stars.png");
                star2.Image = UIImage.FromFile("ZurfersMovil-Stars.png");
                star3.Image = UIImage.FromFile("ZurfersMovil-Stars.png");
                star4.Image = UIImage.FromFile("ZurfersMovil-Stars.png");
                star5.Image = UIImage.FromFile("ZurfersMovil-Stars.png");
                break;
        }


        priceLabel.Text = "USD " + price;
        priceLabel.Font = UIFont.BoldSystemFontOfSize (16);
    }


    public void UpdatedImage (Uri uri)
    {
        imageService.Image = ImageLoader.DefaultRequestImage(uri, this);
    }


    public override void LayoutSubviews ()
    {
        base.LayoutSubviews ();
        imageService.Frame = new RectangleF(10, 10, 50, 33);
        headingLabel.Frame = new RectangleF(70, 4, 240, 25);
        subheadingLabel.Frame = new RectangleF(70, 25, 240, 20);
        priceLabel.Frame = new RectangleF(220, 45, 100, 20);
        star.Frame = new RectangleF(70, 45, 15, 15);
        star2.Frame = new RectangleF(85, 45, 15, 15);
        star3.Frame = new RectangleF(100, 45, 15, 15);
        star4.Frame = new RectangleF(115, 45, 15, 15);
        star5.Frame = new RectangleF(130, 45, 15, 15);
    }
}

}

I want to open another viewcontroller (iPhoneHotelDetailViewController) when the user touch a cell of the table view. But I don not have any idea of how to do this.

Could you help me please.

Thanks in advance for your help.
