#Remarks
End-User Report Designer (WinForms and WPF) displays the following warning when a user attempts to load a potentially unsafe report:
A report is considered unsafe if it or any of its subreports contain any of the following:
The following code prevents users from loading unsafe reports:
static class Program {
static void Main() {
DevExpress.XtraReports.Configuration.Settings.Default.UserDesignerOptions.ReportLoadingRestrictionLevel =
DevExpress.XtraReports.UI.RestrictionLevel.Disable;
}
}
The code above displays the error message when the user attempts to load a potentially unsafe report.
In a restricted environment where all reports are guaranteed to be safe, you can disable this warning and allow users to load any report by setting the UserDesignerOptions.ReportLoadingRestrictionLevel
property to RestrictionLevel.Enable.
The following code lets you determine whether a report is considered unsafe, and displays detected security warnings in the Output window:
var traceSource = DevExpress.XtraPrinting.Tracer.GetSource("DXperience.Reporting",
System.Diagnostics.SourceLevels.Error | System.Diagnostics.SourceLevels.Warning);
var listener = new System.Diagnostics.DefaultTraceListener();
traceSource.Listeners.Add(listener);
try {
new XtraReport1().ShowRibbonDesignerDialog();
} finally {
traceSource.Listeners.Remove(listener);
}
