Design Time serialization

I have a custom control which has a custom designer. When I Enter the
control I am able to loop through all of the controls on the ParentForm and
set their TabIndex property from the designer. If I loop back through the
controls I see that their property is in fact reporting the correct
TabIndex(that I set from the designer)...However when I view the Forms
InitializeComponent code the TabIndex property still reports the original

Is there anyway to force the controls to update the InitializeComponent code
for the Controls through a CustomDesigner by looping through the controls on
a given form?

internal class CustomTextboxDesigner : ControlDesigner
Form2 frm = new Form2();

public override void Initialize(IComponent comp)

protected override void OnMouseEnter()
Form parent = this.Control.Parent.FindForm();
int idx = 100;
foreach (Control ctrl in parent.Controls)
ctrl.TabIndex = idx;
ctrl.Text = idx.ToString();
foreach (Control ctrl in parent.Controls)
frm.RTB.Text += ctrl.Name + " " + ctrl.TabIndex.ToString();

public override bool
CanBeParentedTo(System.ComponentModel.Design.IDesi gner parentDesigner)
return false;

the above code works but never serializes the values back to the form's
designer code.
