using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using Microsoft.Phone.Tasks;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using System.Xml.Linq;
using Microsoft.Phone.Controls;

namespace Nikhils_YoutubeSearch_App
{
public partial class MainPage : PhoneApplicationPage
{
    // Constructor
    public MainPage()
    {
        InitializeComponent();
    }

    private void BtnSearch_Click(object sender, RoutedEventArgs e)
    {
        var wc = new WebClient();
        wc.DownloadStringCompleted += DownloadStringCompleted;
        var src = string.Format("http://gdata.youtube.com/feeds/api/videos?q={0}&format=6", HttpUtility.UrlEncode(TxtSearch.Text));
        wc.DownloadStringAsync(new Uri(src));
    }

    void DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
    {
        var atomns = XNamespace.Get("http://www.w3.org/2005/Atom");
        var medians = XNamespace.Get("http://search.yahoo.com/mrss/");
        var xml = XElement.Parse(e.Result);
        var videos = (from entry in xml.Descendants(atomns.GetName("entry"))
        select new VideoClass
            {
              VideoID = entry.Element(atomns.GetName("id")).Value,
              VideoImg = (from thumbnail in entry.Descendants(medians.GetName("thumbnail"))
            where thumbnail.Attribute("height").Value == "360"
            select thumbnail.Attribute("url").Value).FirstOrDefault(),
            Title = entry.Element(atomns.GetName("title")).Value
            }).ToArray();
        LstVideobox.ItemsSource = videos;
    }

    private void LstVideobox_SelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        var curvid = LstVideobox.SelectedItem as VideoClass;
        if (curvid != null)
        {
            var parsedvid = curvid.VideoID.Split('/');
            var id = parsedvid[parsedvid.Length - 1];
            var url = "vnd.youtube:" + id;

            var myfinalurl = "https://www.youtube.com/embed/" + id;

            var tempurl = "https://www.youtube.com/watch?v=" + id + "?autoplay=1";

            var task = new WebBrowserTask { URL = "https://www.youtube.com/embed/" + id + "?autoplay=1" };
            task.Show();
        }
    }
}
}
