                                    <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">

                                    <img alt="progress" src="images/indicator.gif" height="30px" width="30px" />
                                    Processing...
                                </ProgressTemplate>
                            </asp:UpdateProgress>

C#

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");

Share what is your btnDownload_Click button event do. Not clear by 'download box' here. Update progress is suppose to be there as long as the UpdatePanel partial update to view is not complete.

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 ...";
}
}

the download box is the open-save-cancel download dialogue box that usually comes on our window when we download something. The starnge thing is that even I am redirecting to a different page and on that page all the download box creation code is written incuding that content-disposition etc etc.
Still I get the download box on this page only and doesnt redircts me anywhere and that image stays there even after download process completes. This is all my issue.
