attach textboxes to checkbuttons

[monfu]

Dear All,
I have a series of checkboxes as follows:-
aspx:-
<asp:CheckBoxList id="cblPrint" runat="server" Width="376px" RepeatLayout="Flow"></asp:CheckBoxList>
code behind:-
CType(r.FindControl("cblPrint"), CheckBoxList).DataSource = dsMo.stpSelectAllPrint.DefaultView
CType(r.FindControl("cblPrint"), CheckBoxList).DataTextField = "mo_description"
CType(r.FindControl("cblPrint"), CheckBoxList).DataValueField = "mo_id"
CType(r.FindControl("cblPrint"), CheckBoxList).DataBind()

Now i wish to attach a textbox dynamically to all these checkboxes. How can I do that?
Thanks for your help and time
Johann
