When the ViewReport.aspx page is opened and no prompting for parameters is required, users see only a blank page until the report is ready for display or export. If a report takes more than a few seconds to run, it may be helpful to show a “Please Wait” message to indicate that the report is processing.
To display a “Please Wait” message, use the ViewReportSpin.aspx page instead of ViewReport.aspx. All parameters and other items available to use with ViewReport.aspx remain available when using ViewReport Spin.apx. For example,
The ViewReportSpin.aspx page will display an animated image and a message until the report is ready for display or export. The message text is localized to display in the web browser’s preferred language. When the report is ready, it will be displayed or exported normally just as if the ViewReport.aspx page had been called directly.
