Help with "partial" user control problem

I currently have a form that has 6 group boxes labeled grpbox1, grpbox2, etc.  There are several controls in each of these groupboxes: chklst1, txtbox1, chklst2, txtbox2, etc.  I want to create a single user control class that encompasses all the functionality and design so I can replace the individual ones with an array list of the user control class.  I did this same procedure before a long time ago and was successful.  I'm having a hell of time trying to do it again.  When I add a new user control object to my solution, I get the following:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Text;
using System.Windows.Forms;

namespace Inhallation
{
    public partial class UserControl1 : UserControl
    {
        public UserControl1()
        {
            InitializeComponent();
        }
    }
}

This is before I cut and paste anything.  What's different is this "partial" keyword appearing.  The other isolated class I made looks like this:

using System;
using System.Collections;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Windows.Forms;

namespace Inhallation
{
      /// <summary>
      /// Summary description for clsDisplay.
      /// </summary>
      public class clsDisplay : System.Windows.Forms.UserControl
      {
...............

What am I doing wrong?  I can't follow the same pattern to finish this new control.  Thanks!

Nothing as far as I'm aware, Partial classes is a feature of .NET 2.0 if I'm not mistaken.  This allows you to create a class in 2 seperate files.   e.g.

partial class ATest
      {
            public ATest()
            {
                  i = 5;
                  //contructor
            }
      }

      partial class ATest
      {
            public int i = 0;
      }

This will compile, and work as if it were like this

class ATest
      {
            public int i = 0;
            public ATest()
            {
                  i = 5;
                  //contructor
            }
      }

Hope this helps.

The partial keyword is allows for classes to be split into multiple parts, so here the partial keyword allows the user control to have part of the class be in one file, which contains only the data the user adds, while there is another file, called UserControl1.Designer.cs (or whatever the UserControl is called), which contains the data that the Form Designer uses, which will contain data on the controls, etc.  To access the Designer.cs file, click the + button on the left the user control file to in the Solution Explorer, which is in the top right hand corner to expand out to get the Designer.cs file.
