To store reports in XML format, set the ReportsModuleV2.ReportStoreMode property to the XML in the Application Designer.
Ensure that you use the same ReportStoreMode value in all versions of your application that utilize the same database (WinForms and ASP.NET). Reports that are previously created by users will fail to open after changing the ReportStoreMode value, with the error message similar to "Data at the root level is invalid. Line 1, position 1". To fix the error, use the module updater demonstrated in the How to fix the 'Data at the root level is invalid. Line 1, position 1.' exception after setting the ReportsModuleV2.ReportStoreMode property to XML KB article. All new projects, created with XAF Soution wizard will store reports in the XML format by default.
