   public enum State{Idle, Connecting, Processing}
   //use this field as storage location
   //for FormState property
   private State formState;
   //set attributes for FormState property
   [Browsable(true),
   EditorBrowsable(EditorBrowsableState.Never),
   Description(“Sets the custom Form state”),
   Category(“Custom”)]
   //Creating FormState property
   public State FormState
   {
   get
   {
   return formState;
   }
   set
   {
   formState = value;
   switch (formState)<FONT face=MacUSADigital-Regular size=1>
   {
   case State.Idle:
   this.BackColor = Color.Red;
   this.Text = “Idle”;
   break;
   case State.Connecting:
   this.BackColor = Color.Orange;
   this.Text = “Connecting...”;
   break;
   case State.Processing:
   this.BackColor = Color.Green;
   this.Text = “Processing”;

2. ATTRIBUTES THAT CONTROL THE BEHAVIOR OF A PROPERTY

   

1. Browsable Indicates whether the property is displayed in the Properties window. Its default value is true.

   EditorBrowsable Indicates whether the property should appear in the

   IntelliSense list of an object in the code view. Its value is of

   the EditorBrowsableState enumeration type, with three

   possible values—Advanced, Always, and Never. Its default

   value is Always, which means “always list this property.” If

   you change the value to Never, the property is hidden from

   the IntelliSense feature.

   Description Specifies a description string for the property. When the

   Description property is specified, it is displayed in the

   description area of the Properties window when the property

   is selected.

   Category Specifies the category of the property. The category is used in

   the Properties window to categorize the property list.
