Windows Forms Designer does not display usercontrol

Question

Hi I have a UserControl which does not display in the designer.  Below is the code .  Please help to find out why?

 using System.Data.Linq;
using System.Text;
using System.Windows.Forms;

namespace Presentation
{
    public partial class ItemDiscountUI : UserControl
    {
        public ItemDiscountUI()
        {
            InitializeComponent();
        }

    }
}






namespace Presentation
{
    partial class ItemDiscountUI
    {
        /// <summary> 
        /// Required designer variable.
        /// </summary>
        private System.ComponentModel.IContainer components = null;

        /// <summary> 
        /// Clean up any resources being used.
        /// </summary>
        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }
