Blank report in ASP.NET ReportViewer on iPad/iPhone
|Product||Progress® Telerik® Reporting|
|Report Viewer||ASP.NET WebForms Report Viewer|
This article relates to the Legacy ASP.NET Report Viewer.
The legacy ASP.NET ReportViewer is empty when trying to show a report on iPad or iPhone device.
The reason reports may not be displayed on iPad is because the document is rendered within an iframe and the page uses HTML5 DOCTYPE.
Using an older DOCTYPE declaration such as
HTML4.1 resolves the issue with the Legacy ASP.NET WebForms ReportViewer.
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.
