We have a VB.NET installation of reports that use the Telerik Report Viewer.  They were designed to be opened and viewed in Safari on iPads and have so far been a great boon to our field team's productivity.  But all the BETA tests we have done using Apples new iOS7 have produced the same results: which is none.  We are able to view each report's individual page and can interact with the parameter drop downs at the top of the viewer, but when the report is supposed to render, nothing is produced.  It doesn't even appear as though it has processed any of the parameters (no processing animation).  The new iOS is set to be released by Apple on Sept. 10.  We are putting out a communication to our users that they must not upgrade until we find a solution, but there is little hope that everyone will be compliant on this.

Anyone else have this issue, and does anyone know a work around, or what the problem actually is?

Thanks,
Danny

Hi Danny,

Please test if running your reports with devices running under iOS6 goes as expected. Notice there is an issue using HTML5 DOCTYPE in iOS browsers, so please check if switching to an older DOCTYPE resolves the issue. Also let us know if resizing the Report Viewer once it is made visible with the following JavaScript function shows the viewer:
function ResizeViewer() {
            var viewer = <%=ReportViewer1.ClientID%>;
            viewer.AdjustReportAreaHeight(); 
            }

Since currently only iOS7 beta versions are available for download, we will perform tests based on the released OS, but prior to the official release changes if any will not be included in Telerik Reporting. In addition we are going to release an HTML/JS based ReportViewer, that will have better mobile devices browsers support.

We will be waiting for your details from the performed tests. Feel free to send us examples and private information using our support ticketing system.

Regards,
