How create user control derived from Repeater

[alexb]

Hello ALL.
On my web form i have three Repeater controls.
All of them have same style-sheet and first column that contains select
image.

<itemTemplate>
<table>
<tr>
<td>
<img....../>
</td>
</tr>
</table>
</itemTemplate>

I try to create user control derived from Repeater with this above
declaration.

If it possible, how i can do it.
It's my first attempt creating custom control.

I create calss RepeaterControlBase derived from Repeater
RepeaterControlBase : Repeater

What i need to do ?
