Declare a WithEvents class in Windows Form Designer which is not control base

[EDN Admin]

Hi,
I am making a TabStrip control to hold a number of tabs just like TabControl, but only with the tabs, no page. The control has a "Tabs Collection", which stores a list of "Tab" class. "Tab" is not inherited from Control, but each tab has its events. So when
the user add a "Tab" in the "Tabs Collection", each "Tab" instance should have a (Name) identifier, which user can access it in the code, and with WithEvents keyword so users can add event handlers to each "Tab". The expected out come should similar to this:

<div style="color:Black;background-color:White; <pre>
<span style="color:Blue; Friend TabStrip1 <span style="color:Blue; As TabStrip
<span style="color:Blue; Friend <span style="color:Blue; WithEvents t1 <span style="color:Blue; As Tab
...
<span style="color:Blue; Me.TabStrip1.Tabs.Add(t1)
...
t1.Text = <span style="color:#A31515; "abcdefg"
...
<span style="color:Blue; Private <span style="color:Blue; Sub t1_TextChanged(...) <span style="color:Blue; Handles t1.TextChanged
[/code]

I dont know how to do this if "Tab" is not from Control class. I have tried to add "Tab"s in "Tabs Collection", all "Tab"s were there at design time (only), when I run the application, no "Tab"s was added.
Please could anyone help with my problem?
Here is a part of the code:
