Add Dependent Assemblies to Custom Control

I make a Custom Control but when I use them with drag and drop from the
toolbox I need VS add all reference needed automatically.

This is the situation. I have a class MyNiceControl into a MyWebControls.dll
assembly.
Also I have a MyNiceControlToolboxItem where I think I can implement the
behavior what I want.

MyNiceControl use an object of the class called MyControl1 with inherits
from MyControlParent. All off them in different assemblies.

When I put MyNiceControl into an webform I need the project add a reference
to MyNiceControl assemblie, MyControl1 assemblie and MyControlParent
assemblie.

I make this code to do that.

    [ToolboxData("<{0}:MyNiceControl runat=server></{0}: MyNiceControl >")]
[ToolboxItem(typeof(MyWebControls.MyNiceControlToolboxItem))]
    public class MyNiceControl: WebControl
    {
        Private MyControl1 m_ctrl;
        protected override void RenderContents(HtmlTextWriter output)
        {
            output.Write(â€œ<table><tr><td>â€);
            m_ctrl = new MyControl1();
string text = m_ctrl1.GenerateSomeStuff();
output.Write(text);
            output.Write(â€œ</td></tr><table>â€);
}

}

    [Serializable]
    internal class MyNiceControlToolboxItem: System.Drawing.Design.ToolboxItem
    {

        public MyNiceControlToolboxItem () : base() { }

        private MyNiceControlToolboxItem (SerializationInfo info, StreamingContext
context)

: base(typeof(MyNiceControl))

        {
            Deserialize(info, context);
        }

        protected override IComponent[] CreateComponentsCore(IDesignerHost host)
        {
            ITypeResolutionService service1;
            Assembly assembly1, assembly2;

            IComponent component1;
            IComponent[] componentArray1;

            IContainer container1 = host.Container;
            service1 =
((ITypeResolutionService)host.GetService(typeof(ITypeResolutionService)));

            assembly1 = typeof(MyCtrls.MyControl1).Module.Assembly;
            assembly2 = typeof(MyBaseCtrls.MyParentCtrl).Module.Assembly;

            service1.ReferenceAssembly(assembly1.GetName());
            service1.ReferenceAssembly(assembly1.GetName());

            AssemblyName[] depends = this.DependentAssemblies;
            List<AssemblyName> listDepends = new List<AssemblyName>();
            listDepends.AddRange(depends);

            listDepends.Add(assembly1.GetName());
            listDepends.Add(assembly2.GetName());

            this.DependentAssemblies = listDepends.ToArray();

            component1 = new WUCFormularioCarga();
            container1.Add(component1);
            componentArray1 = new IComponent[] { component1 };

            return componentArray1;
        }
    }

When I put this control into an aspx page in the page adds:
<%@ Register Assembly=" MyWebControls" Namespace=" MyWebControls "
TagPrefix="cc1" %>

And adds a reference to MyWebControls.dll, but nothing about the other
assemblies.

Any ideas?

Thanks in advance.
