                                     Name = (string)rts.Element("name"),
                                     Icon = (string)rts.Element("imageurl"),
                                     VisibleStatus = (string)rts.Element("visiblestatus"),
                                     AppStatus = (string)rts.Element("loginstatus"),

                                     imgBubble =bitmapRed,
                                 }).ToList<SampleCheckedData>();



                this.lstImages.ItemsSource = interestrates;

 private void btnAccept_MouseEnter(object sender, MouseEventArgs e)
        {
            int _id = int.Parse(((System.Windows.FrameworkElement)(e.OriginalSource)).Tag.ToString());
            lstFriendRequuest.Items.RemoveAt(lstFriendRequuest.SelectedIndex);
}

private void btnAccept_MouseEnter(object sender, MouseEventArgs e)
{
    interestrates.RemoveAt(lstFriendRequuest.SelectedIndex);
}
