using System.ComponentModel;
using System.Text;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace Samples.AspNet.CS.Controls
    public class SimpleCustomControl : WebControl

        // Set Filterable attribute to specify that this 
        // property does not support device filtering.
        public string ProductID
                return _productID;
