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:

C#
VB.NET

csharp

static class Program {
    static void Main() {
        DevExpress.XtraReports.Configuration.Settings.Default.UserDesignerOptions.ReportLoadingRestrictionLevel =
    DevExpress.XtraReports.UI.RestrictionLevel.Disable;
    }
}

Partial Friend Class MyApplication
    Public Sub New()
        MyBase.New(Global.Microsoft.VisualBasic.ApplicationServices.AuthenticationMode.Windows)
        DevExpress.XtraReports.Configuration.Settings.Default.UserDesignerOptions.ReportLoadingRestrictionLevel = _
            DevExpress.XtraReports.UI.RestrictionLevel.Disable
    End Sub
End Class

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:

C#
VB.NET

csharp

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);
}

Dim traceSource = DevExpress.XtraPrinting.Tracer.GetSource("DXperience.Reporting", _ 
    System.Diagnostics.SourceLevels.[Error] Or System.Diagnostics.SourceLevels.Warning)
Dim listener = New System.Diagnostics.DefaultTraceListener()
traceSource.Listeners.Add(listener)
Try
    New XtraReport1().ShowRibbonDesignerDialog()
Finally
    traceSource.Listeners.Remove(listener)
End Try
