Composite Component Properties???

[Joe Mamma]

Ok, I am missing something here. . .

 

I have a two components -

Basic (a simple component with one string property 'TheString')

Composite (a component with one property - a Basic component)

 

when dropped on a form (Basic _basic; Composite _composite), Properties of both components are visible, with the Basic property of Composite rightly depicted as a collapsible property.

 

When I change _basic.TheString using the property editor, the following code is written in the form's InitializeComponent method:

 

this._basic.TheString = "Foobar";

 

but when I change _Composite.Basic.TheString in the property editor, I expected to see:

this._composite.Basic.TheString = "Foobar";

 

but I didn't. I assume I am missing an attribute, but I cant figure it out.

 

here is my code:

 

basic.cs:

using System;
using System.ComponentModel;
namespace TestComponent
{
public class Basic : System.ComponentModel.Component
{
 private System.ComponentModel.Container components = null;
 private string _string;
 public string TheString
 {
  get{ return _string; }
  set{_string = value;}
 }
 public Basic(System.ComponentModel.IContainer container)
 {
  container.Add(this);
  InitializeComponent();
 }
 public Basic()
 {
  InitializeComponent();
 }
 protected override void Dispose( bool disposing )
 {
  if( disposing )
  {
   if(components != null)
   {
    components.Dispose();
   }
  }
  base.Dispose( disposing );
 }
 private void InitializeComponent()
 {
  components = new System.ComponentModel.Container();
 }
}
}

 

composite.cs

using System;
using System.ComponentModel;
namespace TestComponent
{
public class Composite : System.ComponentModel.Component
{
 private System.ComponentModel.Container components = null;
 private Basic _basic;
 public Basic Basic
 {
  get {return _basic;}
 }
 public Composite(System.ComponentModel.IContainer container)
 {
  container.Add(this);
  InitializeComponent();
  _basic = new Basic(components); 
 }
 public Composite()
 {
  InitializeComponent();
  _basic = new Basic(components); 
 }
 protected override void Dispose( bool disposing )
 {
  if( disposing )
  {
   if(components != null)
   {
    components.Dispose();
   }
  }
  base.Dispose( disposing );
 }
 private void InitializeComponent()
 {
  components = new System.ComponentModel.Container();
 }
}
}

 

Mainform.cs:

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
namespace TestComponent
{
public class Mainform : System.Windows.Forms.Form
{
 private System.ComponentModel.IContainer components;
 private Basic _basic;
 private Composite _composite;
 public Mainform()
 {
  InitializeComponent();
 }
 protected override void Dispose( bool disposing )
 {
  if( disposing )
  {
   if (components != null) 
   {
    components.Dispose();
   }
  }
  base.Dispose( disposing );
 }
 private void InitializeComponent()
 {
  this.components = new System.ComponentModel.Container();
  this._basic = new TestComponent.Basic(this.components);
  this._composite = new TestComponent.Composite(this.components);
  this.AutoScaleBaseSize = new System.Drawing.Size(5, 13);
  this.ClientSize = new System.Drawing.Size(248, 152);
  this.Name = "Form1";
  this.Text = "Form1";
 }

 static void Main() 
 {
  Application.Run(new Mainform());
 }
}
}
