I've been getting this weird error from past couple of days. I've nothing to do with the resource.axd file. And hence somehow i'm not being able to understand how to fix this problem.

To give a background, I've a Search page, which has 2 calendar (these are infragisitc controls) control and search button. when i click on search button without changing calendar dates, my page works fine.

After hitting search, if i change calendar dates, it still works fine. Problem comes when i come to Search page and first thing i do is change calendar date, then i hit search button.

On click of search button, i'm calling progress bar user control, attached is the code of Progress bar control.

else

Surprisingly, I'm uable to re-produce this error in my Dev and QA environment. My Prod environment throws this Javascript error however. I've reinstalled ASPAJAXSetup on Prod but no reuslts.

I'm using Infragistic control library. I've also re-installed infragisitc library too. Can this be because of this?

Please help, My app is in production and users are not being able to do anything.

Thanks in advance.

Hi s14df

Your code works fine on our lab, just like the following demo.

<%@ Page Language="C#" %> <%@ Register Assembly="System.Web.Extensions" Namespace="System.Web.UI" TagPrefix="asp" %> <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxtoolkit" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <script runat="server"> </script> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> <style type="text/css"> .modalBackground { background-color: Gray; filter: alpha(opacity=50); opacity: 0.50; } </style> <script type="text/javascript" language="javascript"> var ModalProgress = '<%= ModalProgress.ClientID %>'; </script> </head> <body> <form id="form1" runat="server"> <div><ajaxtoolkit:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server"> </ajaxtoolkit:ToolkitScriptManager> <asp:Panel ID="panelUpdateProgress" runat="server" CssClass="updateProgress"> <asp:UpdateProgress ID="UpdateProg1" DisplayAfter="0" runat="server"> <ProgressTemplate> <asp:Image runat="server" ID="imgLoading" ImageUrl="me.jpg" /> </ProgressTemplate> </asp:UpdateProgress> </asp:Panel> <ajaxtoolkit:ModalPopupExtender ID="ModalProgress" runat="server" TargetControlID="panelUpdateProgress" RepositionMode="RepositionOnWindowResizeAndScroll" BackgroundCssClass="modalBackground" PopupControlID="panelUpdateProgress" /> </div> <script type="text/javascript" language="javascript"> Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(beginReq); Sys.WebForms.PageRequestManager.getInstance().add_endRequest(endReq); //Create buffer to be used for JAWS - 508 compliance. //prepareBuffer(); function beginReq(sender, args) { // shows the Popup $find(ModalProgress).show(); } function endReq(sender, args) { // shows the Popup $find(ModalProgress).hide(); //updateBuffer(); } function prepareBuffer() { var objNew = document.createElement('p'); var objHidden = document.createElement('input'); objHidden.setAttribute('type', 'hidden'); objHidden.setAttribute('value', '1'); objHidden.setAttribute('id', 'virtualbufferupdate'); objHidden.setAttribute('name', 'virtualbufferupdate'); objNew.appendChild(objHidden); document.body.appendChild(objNew); } function updateBuffer() { var objHidden = document.getElementById('virtualbufferupdate'); if (objHidden) { if (objHidden.getAttribute('value') == '1') objHidden.setAttribute('value', '0'); else objHidden.setAttribute('value', '1'); } } </script> <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate> <asp:Button ID="Button1" runat="server" Text="Button" /> </ContentTemplate> </asp:UpdatePanel> </form> </body> </html>

I am not sure whether the infragisitc is conflict with ASP.NET AJAX. So, I would like to suggest you try to contact the third-party control service provider for their information.

Thanks.
