can i use ajaxToolkit:ModalPopupExtender in visual studio 2005

I have a project in asp.net web form which is developed in visual studio 2005. I am trying to use modal popup(using ajaxToolkit:ModalPopupExtender) but it's not working.But it's perfectly works in vs2010. This make me confused. Is it possible to make it happen in vs2005.

Yes it's possible, you try to flow this code --add ajaxcontroltoolkit---

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>

-- take fale button---

<asp:LinkButton Text="" ID="lnkFake" runat="server" />

--- then you take this code---

 <ajaxToolkit:ModalPopupExtender ID="mpe" EnableViewState="true" runat="server" PopupControlID="pnlPopup"
                TargetControlID="lnkFake" CancelControlID="btnClose" BackgroundCssClass="modalBackground">
            </ajaxToolkit:ModalPopupExtender>
            <asp:Panel ID="pnlPopup" runat="server" CssClass="modalPopup" Width="50%" Style="display: none;
                background-color: lightsteelblue;">
                <asp:Label runat="server" ForeColor="Green" ID="lblModelShow" Font-Size="12px" Font-Bold="true"></asp:Label>
                <div style="display: block; overflow: auto; width: 100%; height: 700px; text-align: center"
                    class="textarea">
                    <div class="row">
                        <div id="Div1" style="overflow: scroll; height: 620px;">
                            <br />
                            <br />
                            <asp:GridView ID="GridView1" runat="server" Height="1px" Width="750px" CellPadding="4"
                                BackColor="White" BorderColor="#3366CC" BorderStyle="None" BorderWidth="1px">
                                <Columns>
                                    <asp:TemplateField HeaderText="SL">
                                        <ItemTemplate>
                                            <%#Container.DataItemIndex+1 %>
                                        </ItemTemplate>
                                    </asp:TemplateField>
                                </Columns>
                                <FooterStyle BackColor="#99CCCC" ForeColor="#003399" />
                                <RowStyle CssClass="AlternatColor" Width="80px" ForeColor="#003399" />
                                <PagerStyle BackColor="#99CCCC" ForeColor="#003399" HorizontalAlign="Left" />
                                <SelectedRowStyle BackColor="#009999" Font-Bold="True" ForeColor="#CCFF99" CssClass="AlternatColor" />
                                <HeaderStyle BackColor="#003399" BorderStyle="Double" Width="80px" Font-Bold="True"
                                    ForeColor="#CCCCFF" />
                            </asp:GridView>
                        </div>

 mpe.Show();
