Disable the Audit Trail Module

• Sep 23, 2020

This topic demonstrates two options you can use to disable the Audit Trail Module in your application:

• In a Configuration File
  Disable the Module unconditionally.
• In Application Code
  Disable the Module for a particular scenario.

In a Configuration File

Add the EnableAuditTrail key with the False value to an application’s configuration file, as shown below:

XML

<appSettings>
    <!-- ... -->
    <add key="EnableAuditTrail" value ="False"/>
    <!-- ... -->
</appSettings>

In Application Code

Access the Audit Trail Module and specify its AuditTrailModule.Enabled property in the XafApplication.LoggedOn event handler, as shown below:

C#

using DevExpress.ExpressApp.Win;
using DevExpress.ExpressApp.AuditTrail;
// ...
public class MySolutionWinApplication : WinApplication {
    // ...
    protected override void OnLoggedOn(LogonEventArgs args) {
        base.OnLoggedOn(args);
        AuditTrailModule auditTrailModule = this.Modules.FindModule<AuditTrailModule>();
        if(Security.UserName == "John")
            auditTrailModule.Enabled = false;
        }
    }
}

VB.NET

Imports DevExpress.ExpressApp.Win
Imports DevExpress.ExpressApp.AuditTrail
' ...
Public Class MySolutionWinApplication
    Inherits WinApplication
    ' ...
    Protected Overrides Sub OnLoggedOn(ByVal args As LogonEventArgs)
        MyBase.OnLoggedOn(args)
        Dim _auditTrailModule As AuditTrailModule = Me.Modules.FindModule(Of AuditTrailModule)()
        If Security.UserName = "John" Then 
            _auditTrailModule.Enabled = False
    End Sub
End Class
