ASP User control: Cannot pass parameter from within a loop

I can't pass a variable to an user control (ascx) from an asp page (aspx) within a loop.

I want to recursively iterate a custom control with a foreach loop (would like to avoid asp:Repeater, but if it's the only solution I'm open to suggestions about that.

I Used all the server inline tags I know, but result either gets the full

<%= stringvalue %>

to the control (meaning in the string variable which receives the parameter in the control, I see the expression and not the value) or null when I use binding tags

<%# stringvalue %>

Here's what I'm doing in the aspx file:

<%foreach (string item in listItems)
                    {
                        tempItem = item;
                        %>
                    <uc:CustomControl runat="server" id="controlId" AutoPostback="true" parameterCustom='<%# Eval("tempItem")%>'/>

                <%
                    }%>

And in the control I have

public string parameterCustom {get;set;}

which should receive the value

@freefaller Sorry, fixed. My code is as it's shown now <%# Eval("x") %> – Liquid Core May 10 '19 at 12:06

I've never tried to create multiple controls this way, I've always used a `` which I'm aware you'd like to avoid. My main concern here is having multiple controls with an `id` of `controlId` – freefaller May 10 '19 at 12:07
@freefaller I'll try that way waiting for answers – Liquid Core May 10 '19 at 12:08
Use a Repeater... – VDWWD May 10 '19 at 12:33
@VDWWD I tried to avoid Repeater because it's clunky and retarded – Liquid Core May 10 '19 at 13:18
