                    <asp:Repeater ID="rp_tagsTopics" runat="server">
                        <ItemTemplate>
                            <h6>

                    <div id="controls">
                        <asp:ImageButton ID="imgbtnBookmark" runat="server"   OnClick="imgbtnBookmark_Click" />
                        <asp:DropDownList ID="ddlGroup" runat="server" DataSourceID="SqlDS_Groups" DataTextField="name" DataValueField="id" AppendDataBoundItems="True" OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged" >
<asp:ListItem Value="-1">Select Group</asp:ListItem>


protected void imgbtnBookmark_Click(object sender, System.Web.UI.ImageClickEventArgs e)
{
    Bookmark bm = new Bookmark();
    HiddenField hiddenField = rptGroup.FindControl("hf_resID") as HiddenField;
    bm.UserID =  
    Guid.Parse(Membership.GetUser(HttpContext.Current.User.Identity.Name).ProviderUserKey.ToString());
    bm.Resoursce.ResourceID = Convert.ToInt32(hiddenField.Value);
    Bookmark.Insert(bm);
}

Try this, change you button tag to pass id as CommandArgument value

<asp:ImageButton ID="imgbtnBookmark" runat="server"   
    OnClick="imgbtnBookmark_Click" 
    CommandArgument='<%#  Eval("Id") %>'/>

in your button click event you can access id using

bm.Resoursce.ResourceID = Convert.ToInt32(e.CommandArgument.ToString());
