You cant have a page with multiple controls with the same ID. It should not compile and if it did it would be a really bad practice (same name also bad practice). These best thing you could do is to create a dynamic ID as you populate the page with controls. i.e. have a integer counter, i, and then increment it by 1 every-time you add a control.
so eventually you page will have a list of controls on the page like this:
<asp:checkboxlist id="CheckBoxList1" runat="server">
 <asp:Checkbox id="checkbox1" name="checkbox" runat="server">
 <asp:Checkbox id="checkbox2" name="checkbox" runat="server">
 <asp:Checkbox id="checkbox3" name="checkbox" runat="server">
<asp:checkbox/>

when your asp.net button is pressed you can cycle through all your controls like this:

string values;

foreach ( CheckBox box in CheckBoxList1)
 if if (box.Checked)
 {
   values = values + box.Value;    
}
