Eval script for server side control's ID property?

Question

Using the following Eval script for setting ID property causes error. Error message: the server tag is not well formed.

 <asp:Panel runat="server" ID="<%# Eval("RENTER_ID") %>" Visible="false">

Even replacing "" with '' of ID property generates error. While using '', its error message

"The ID property of a control can only be set using the ID attribute in the tag and a simple value. Example: <asp:Button runat="server" id="Button1" />"

Any ideas to solve this?

Answer 1

You can't do it.

Why do you need to? If it's so you can reference it at some point, you can access the client-side id via the property ClientID.

Example, as requested:

<asp:Repeater runat="server" ID="repFoo">
    <ItemTemplate>
        <asp:Panel runat="server" ID="pnlFoo">
            <input type = "button"
                onclick = "alert('<%# Container.FindControl("pnlFoo").ClientID %>');"
                value   = "click to get id for <%# Container.ItemIndex %>" />
        </asp:Panel>
    </ItemTemplate>
</asp:Repeater>
