Hi Jim,

Thank you for your response.  

Yes, you could put the controls on several panels on the form and
enable/disable the panels. It is an option.

You can also use databinding to enable/disable the controls on the form. I
mean that you could bind the ReadOnly or Enabled property of the controls
to a custom business object's field and then you could change the value of
this field in the custom business object to enable/disable the
corresponding controls.

The following is a sample.
public partial class Form1 : Form
   {
       private BusinessClass businessObj;
       public Form1()
       {
           InitializeComponent();
           businessObj = new BusinessClass();
           this.textBox1.DataBindings.Add("ReadOnly", businessObj,
"ReadOnly");
           this.textBox2.DataBindings.Add("ReadOnly", businessObj,
"ReadOnly");
           businessObj.ReadOnly = true;
       }
   }
   public class BusinessClass
   {
       private bool _ReadOnly = true;
       public bool ReadOnly
       {
           get { return _ReadOnly; }
           set { _ReadOnly = value; }
       }
   }

Hope this is helpful to you.
If you have any other concerns or need anything else, please don't hesitate
to let me know.

Sincerely,
