Give command name field for Control like this:

XML

<ItemTemplate>
<asp:ImageButton ID="Image1" runat="server" CommandArgument='<%# Eval("product_id") %>' CommandName="click" Height="200px" ImageUrl='<%# Eval("url")%>' Width="200px" />
        </ItemTemplate>

and then in code behind:

C#

protected void Datalist1_ItemCommand(object source, DataListCommandEventArgs e)
    {
        if (e.CommandName == "click")
        {
            // your logic
        }
     }
