Blank report in ASP.NET ReportViewer on iPad/iPhone

This article relates to the Legacy ASP.NET Report Viewer.
Description
The legacy ASP.NET ReportViewer is empty when trying to show a report on iPad or iPhone device.
Possible Cause
The reason reports may not be displayed on iPad is because the document is rendered within an iframe and the page uses HTML5 DOCTYPE.
Solution
Using an older DOCTYPE declaration such as HTML4.1
resolves the issue with the Legacy ASP.NET WebForms ReportViewer.
Notes
The HTML5 Report Viewer introduced in Telerik Reporting Q3 2013 also provides solution for the issue. The viewer uses HTML5/JS/CSS3 technologies and is HTML5 browsers compliant.
