Accessing control inside datalist

Question

my name is Prince. I have a datalist named datalist1, i inputed a label, image and button in the datalist. I inputed the image of a field from my database in my image tag and the id of the same field in my label tag. I'm trying to implement ecommerce functionality, so when i click the button it'll redirect me to my product page AND input the id(from the label tag) in the url path.

ive tried:

     protected void img_Click(object sender, EventArgs e)
    {
        DataListItem dli = this.DataList1.Controls[this.DataList1.Controls.Count - 1] as DataListItem;
        Label lbl = dli.FindControl("itemiD") as Label;
        Response.Redirect("product.aspx?id="+lbl.Text+"");
    }

The above code worked, but it only game me the id of the last item in my datalist1.

Then i tried the following below

     protected void img_Click(object sender, EventArgs e)
    {
       foreach (DataListItem item in DataList1.Items)
           {
               Label lbl = (Label)item.FindControl("itemiD");
               Response.Redirect("product.aspx?id=" + lbl.Text + "");
           }
    }

The following worked as well, but only gave me the id of the first item in my datalist1. Please how do i get the id of the clicked item in the datalist to the url.

P.S img_Click() is the event to handle the code :)

Here is the front end

    <asp:DataList ID="DataList1" runat="server" RepeatColumns="4" RepeatDirection="Horizontal" Width="100%" BorderColor="#336699" BorderStyle="None" BorderWidth="2px" OnSelectedIndexChanged="DataList1_SelectedIndexChanged">
            <ItemTemplate>
                <div style="height:auto;" class="dimage">
                    <asp:Label runat="server" Text='<%#Eval("Name") %>' Font-Bold="true" Font-Size="10pt" ForeColor="#336699" Width="100%"/>
                    <br />
                    <img id="Image2" runat="server" src='<%#"GetImage.aspx?id="+Eval("id") %>' style="width:auto; height:150px;" class="d_image" onclick="img_Click" /> <br />
                     <asp:Label runat="server" Text='<%#Eval("id") %>' ID="itemiD" />
                     <br />
                    <asp:Button ID="Button1" runat="server" OnClick="img_Click" Text="Buy Now" /><br /><br />
                </div>
            </ItemTemplate>
            <ItemStyle HorizontalAlign="Center" VerticalAlign="Top" />
        </asp:DataList>
