I have 2 .aspx pages. 1. Reporter.aspx 2. Report.aspx Inside Reporter.aspx I have an IFRAME and Report.aspx is kept inside the IFRAME after submitting Report.aspx to server (to load report), I want to do another thing like showing some progress or something like that. My pages looks like the following

Reporter.aspx: ....................

    
   
    
        
            
                
                    
                        
Loading....
                        

                            
                        
                           
                
            
                                
    
    
    

        
    

Report.aspx: ..................

I have a button with ID="btnGenerateReport" and when I click it, it loads report. Some big reports take almost 2 hours to be generated and that is why I have set AsyncPostBackTimeout="7200" inside asp:ScriptManager. It works perfectly in different browsers like FireFox, Google Chrome, Safari but not in IE. When I click on Generate button using browser IE8, after few seconds it shows the following javascript error:

Then I just put EnablePartialRendering="false" to asp:ScriptManager and tried to see if i can see some difference. After this, i click on Generate report button using IE8 and found another javascript error after just few seconds like 10-15. Here is the error:

Is there anyone who can help me getting out from this IE error. I am in serious trouble.
