Created an attachment (id=342536)
 --> (http://bugzilla.novell.com/attachment.cgi?id=342536)
Sample project to reproduce the defect

User-Agent:       Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR
2.0.50727; .NET CLR 3.0.04506.30; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729)

When a Control's parent is changed using System.ComponentModel code, its
ParentChanged event is not fired. Also the ControlAdded (and i assume the
ControlRemoved too) event of the parent control/form is not fired. Using the
standard .NET framework, the events are fired.

Example code:
PropertyDescriptor childProperty =
TypeDescriptor.GetProperties(MyNiceForm)["Controls"];
System.Collections.IList childs = childProperty.GetValue(MyNiceForm) as
System.Collections.IList;
childs.Add(MyNiceControl);

Reproducible: Always

Steps to Reproduce:
1. Open the sample project from the attachement
2. Compile the sample project and run it using .NET
3. Compile the sample project and run it using Mono
Actual Results:  
The checkbox is not checked using Mono, but checked using .NET

Expected Results:  
The checkbox should be checked in both environments.
