A good approach is to set the ItemsSource of the RadCarousel to the SelectedItems Property of the grid.
private void Button1_Click(object sender, RoutedEventArgs e)
RadCarouselControl carousel = new RadCarouselControl();
carousel.Carousel.ItemsSource = this.playersGrid.SelectedItems;
window.Content = carousel;
Following up the code above, the RadCarousel will appear on clicking on Button1.
If you want to show only one of the properties in the Items of the carousel (in your case just the picture), you can set the ItemTemplate of RadCarosel and bind the item to the desired property. For example:
In this case the items in the carousel will be the names of the players.
