Hi,
Try this:

HTML

OnClientClick='<%# String.Format("javascript:return redirect(\"{0}\")", Eval("idProduct").ToString()) %>'

And then change your JavaScript function to get a parameter(idProduct).
Your function:

XML

<script language="javascript">
    function redirect(idProduct) {
        window.location = "Product_Detail.aspx?idProduct=" + idProduct;
    }
</script>

Cheers

Then debug your function, try to watch what is being send in the 'redirect' function

One more thing, have you removed '<%# Eval("idProduct") %>' which was in your function as I moved them in the <asp:Image tag?

It seems it does not have that propery!! That exists just in Button, and LinkButton controls in the MSDN
