I handle the OnCommand client-side event for a Grid. I pull out the ID of the record of interest. Part of that record is a byte stream that contains the contents of a PDF file. The OnCommand handler calls radopen to display an aspx page:

    
                        function RadGrid1_OnCommand(sender, eventArgs) {  
        
                            var nID = sender.get_masterTableView().get_dataItems()[0].getDataKeyValue("ID");  
        
                            var commandName = eventArgs.get_commandName();  
        
                            if (commandName == "PDF") {  
        
                                var wnd = window.radopen("/ShowInvoicePDF.aspx?ID=" + nID, null);  
        
                                return false;  
        
                            }  
        
                        }

The ShowInvoicePDF markup is just like the VS2010 wizard created it and I added nothing to it. I do this in the Page_Load method.

    
                    protected void Page_Load(object sender, EventArgs e)  
        
                    {  
        
                        int nID = Convert.ToInt32(Request.QueryString["ID"]);  
        
                        Invoice invoice = Invoice.FindByID(nID);  
        
                        Response.Clear();  
        
                        Response.ClearContent();  
        
                        Response.ClearHeaders();  
        
                        Response.Buffer = true;  
        
                        Response.ContentType = "Application/pdf";  
        
                        Response.AddHeader("Accept-Ranges", "bytes");  
        
                        Response.AddHeader("Accept-Header", invoice.PDFData.Length.ToString());  
        
                        Response.AddHeader("Cache-Control", "public");  
        
                        Response.AddHeader("Cache-Control", "must-revalidate");  
        
                        Response.AddHeader("Pragma", "public");  
        
                        Response.AddHeader("expires", "0");  
        
                        //Response.BinaryWrite(invoice.PDFData);  
        
                        Response.OutputStream.Write(invoice.PDFData, 0, invoice.PDFData.Length);  
        
                        //Response.Flush();  
        
                        //Response.Close();  
        
                        Response.End();  
        
                    }

When the webapp is run using IE 8 under Windows 7, the radwindow comes up but all I see is the rotating RadAjaxLoadingPanel wheel. If I use FireFox it works fine. If I run the ShowInvoicePDF.aspx file directly from the IE browser, it works fine, so there must be some kind of interaction with javascript/ajax/radwindow happening. Why is this happening (an answer of "because you are using MS IE" is not a valid response)? What do I need to do to make it work on all browsers?
