Do I need to make my update panel a post back to hide the image ? Doing so will cause download box disappear ??? I am not sure . Please help me guys.

Here is my HTML mark up of the update panel and update progress.:

<pre lang="HTML">
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
                                <ContentTemplate>
                                    <asp:Button ID="btnDownload" runat="server" CssClass="Admin_Button" OnClick="btnDownload_Click"
                                        Text="Download" Width="91px" UseSubmitBehavior="False" />
                                </ContentTemplate>
                            </asp:UpdatePanel>
                            <asp:UpdateProgress ID="updProgress" AssociatedUpdatePanelID="UpdatePanel1" runat="server">
                                <ProgressTemplate>
                                    <img alt="progress" src="images/indicator.gif" height="30px" width="30px" />
                                    Processing...
                                </ProgressTemplate>
                            </asp:UpdateProgress>

protected void btnDownload_Click(object sender, EventArgs e)
   {
 lblMsg.Visible = false;
                     lbl_date_error.Visible = false;
                     strHSCODE = Convert.ToString(ViewState["strHSCODE"]);
                     strDataType = Convert.ToString(ViewState["strDataType"]);
                     strCombination = Convert.ToString(ViewState["strCombination"]);
                     strProd = Convert.ToString(ViewState["strProd"]);
                     strProd_not = Convert.ToString(ViewState["strProd_not"]);

                     DataTable iResult = bl_my_account_client.Query_Data(strDataType, date_from_by_user, date_to_by_user, strHSCODE, strCombination, strProd, strProd_not);


                     if (iResult.Rows.Count != 0)
                     {
                         HttpContext.Current.ApplicationInstance.CompleteRequest();
                         this.Page.ClientScript.RegisterClientScriptBlock(GetType(), "JScript1", "hideImage();", true);

                        
                         Session["Download"] = iResult;
                         Response.Redirect("Download.aspx");
                         

                     }
                     else
                     {
                         lbl_date_error.Visible = true;
                         lbl_date_error.Text = "Error: This request cannot be processed ...";
                     }
}
