It all seems to work fine for me, against the 1.1 and 2.0 (beta) framework.
Maybe there's something in your project or source that is causing this. Can
you post the complete source code for the MpeParameter and MpeGroupBox
classes?

Well, that is not that secret:

So, the MpeParameter Class:

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

public delegate void MpeChangedEventHandler(object sender, EventArgs e);

namespace Speedware.MpeControls
{
public abstract class MpeParameter : UserControl
{
public MpeParameter()
{
this.mpeIsOptional = true;
this.mpeByValue = true;
this.mpeGenerate = true;
this.mpeInput = true;
this.mpeFieldName = "WS-";
this.mpeValue = 0;
this.mpeFieldType = MpeEnumFieldTypes.I16;
this.mpeClass = this.GetType().Name;
}

public enum MpeEnumFieldTypes
{
CA, I16, U16, U32
}

public enum MpeEnumBitsetTypes
{
MpeBitsetCheckBox, MpeBitsetUpDown, MpeBitsetComboBox
}

public event MpeChangedEventHandler MpeGenerateChanged;

protected virtual void OnMpeGenerateChanged(EventArgs e)
{
if (MpeGenerateChanged != null)
MpeGenerateChanged(this, e);
}

[Category("MPE")]
public bool MpeGenerate
{
get { return this.mpeGenerate; }
set {
this.mpeGenerate = value;
this.OnMpeGenerateChanged(EventArgs.Empty);
}
}

[Category("MPE")]
public virtual int MpeValue
{
get { return this.mpeValue; }
set { this.mpeValue = value; }
}

[Category("MPE")]
public bool MpeByValue
{
get { return this.mpeByValue; }
set { this.mpeByValue = value; }
}

[Category("MPE")]
public bool MpeIsOptional
{
get { return this.mpeIsOptional; }
set { this.mpeIsOptional = value; }
}

[Category("MPE")]
public string MpeFieldName
{
get { return this.mpeFieldName; }
set { this.mpeFieldName = value; }
}

[Category("MPE")]
public bool MpeInput
{
get { return this.mpeInput; }
set { this.mpeInput = value; }
}

[Category("MPE")]
public virtual MpeEnumFieldTypes MpeFieldType
{
get { return this.mpeFieldType; }
set { this.mpeFieldType = value; }
}

private bool mpeIsOptional;
private bool mpeByValue;
private bool mpeGenerate;
private bool mpeInput;
private string mpeFieldName;
private string mpeClass;
private int mpeValue;
protected MpeEnumFieldTypes mpeFieldType;

private void InitializeComponent()
{
this.SuspendLayout();
//
// MpeParameter
//
this.Name = "MpeParameter";
this.Size = new System.Drawing.Size(322, 258);
this.ResumeLayout(false);

}
}
}
--------------------------------------------
And the MpeGroupBox, which is a GroupBox + a CheckBox:

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

namespace Speedware.MpeControls
{
[Designer(typeof(ParentControlDesigner))]
public partial class MpeGroupBox : MpeParameter
{
public MpeGroupBox()
{
InitializeComponent();
}

.......

}
}

I am new in this kind of tools and languages, I am coming from MPE + COBOL
environment, I guess my problem is trivial.

Thanks,

Christophe.
