Hi Everyone,
I am facing very much weird problem today. I have one ASP.NET application (which is published to windows azure) with page reportviewer.aspx where I have added report viewer control to render SQL Azure report.
If I open this page in IE, I can see reports and can export SSRS report to any format (PDF, XML, etc..) through standard report viewer toolbar.
Problem start when...
I have created one aspx page in SharePoint online and placed iframe which is referring above reportviewer.aspx page. This iframe renders report perfectly. But when I export this report to any format from standard report viewer toolbar, it always throw error"ASP.NET session has expired or could not be found".
while exporting reports, it opens one popup window with below URL http://<asp.net application root url>/Reserved.ReportViewerWebControl.axd?ReportSession=obabgrnwrzao4g4502bjng55&Culture=1033&CultureOverrides=True&UICulture=1033&UICultureOverrides=True&ReportStack=1&ControlID=5f9d9bbef05d43eaa7b76f724e49dcb4&OpType=Export&FileName=Construction+Report&ContentDisposition=OnlyHtmlInline&Format=PDF
Thanks in advance to everyone!
