SecurityStrategy.AnonymousAllowedTypes Property

Specifies types that users can access anonymously before they log in.

Namespace: DevExpress.ExpressApp.Security

Assembly: DevExpress.ExpressApp.Security.v21.2.dll

NuGet Package: DevExpress.ExpressApp.Security

Declaration

C#

[Browsable(false)]
public IList<Type> AnonymousAllowedTypes { get; }

VB.NET

<Browsable(False)>
Public ReadOnly Property AnonymousAllowedTypes As IList(Of Type)

Property Value

Type	Description
IList<Type>	A list of types that users can access anonymously.

Remarks

Anonymous access may be required when you use custom logon parameters and want to display certain data in the logon window before a user logs on. Add the required types to the AnonymousAllowedTypes collection to grant access to these types before a successful user authentication. This code should be executed before the application displays the logon window.

The following examples demonstrate how to specify this property:

WinForms

File: MySolution.Win\WinApplication.cs(.vb) (the WinApplication descendant’s constructor).

C#

using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Security;
using DevExpress.ExpressApp.Win;
// ...
public partial class CustomLogonParametersExampleWindowsFormsApplication : WinApplication {
    // ...
    public CustomLogonParametersExampleWindowsFormsApplication() {
        // ...
        ((SecurityStrategy)Security).AnonymousAllowedTypes.Add(typeof(Company));
        ((SecurityStrategy)Security).AnonymousAllowedTypes.Add(typeof(Employee));
    }
    // ...
}

VB.NET

Imports DevExpress.ExpressApp
Imports DevExpress.ExpressApp.Security
Imports DevExpress.ExpressApp.Win
' ...
Public Partial Class CustomLogonParametersExampleWindowsFormsApplication
    Inherits WinApplication
    ' ...
    Public Sub New()
        (CType(Security, SecurityStrategy)).AnonymousAllowedTypes.Add(GetType(Company))
        (CType(Security, SecurityStrategy)).AnonymousAllowedTypes.Add(GetType(Employee))
    End Sub
    ' ...
End Class

ASP.NET Web Forms

File: MySolution.Web\WebApplication.cs(.vb) (the WebApplication descendant’s constructor).

C#

using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Security;
using DevExpress.ExpressApp.Web;
// ...
public partial class CustomLogonParametersExampleAspNetApplication : WebApplication {
    // ...
    public CustomLogonParametersExampleAspNetApplication() {
        // ...
        ((SecurityStrategy)Security).AnonymousAllowedTypes.Add(typeof(Company));
        ((SecurityStrategy)Security).AnonymousAllowedTypes.Add(typeof(Employee));
    }
    // ...
}

VB.NET

Imports DevExpress.ExpressApp
Imports DevExpress.ExpressApp.Security
Imports DevExpress.ExpressApp.Web
' ...
Public Partial Class CustomLogonParametersExampleAspNetApplication
    Inherits WinApplication
    ' ...
    Public Sub New()
        (CType(Security, SecurityStrategy)).AnonymousAllowedTypes.Add(GetType(Company))
        (CType(Security, SecurityStrategy)).AnonymousAllowedTypes.Add(GetType(Employee))
    End Sub
    ' ...
End Class

ASP.NET Core Blazor and Web API

File: MySolution.Blazor.Server\Startup.cs (the ConfigureServices method).

C#

using DevExpress.ExpressApp.Security;
using Microsoft.Extensions.DependencyInjection;
// ...
public class Startup {
    // ...
    public void ConfigureServices(IServiceCollection services) {
        // ...
        services.AddXafSecurity(options => {
            // ...
            options.Events.OnSecurityStrategyCreated = securityStrategy => {
                // ...
                ((SecurityStrategy)securityStrategy).AnonymousAllowedTypes.Add(typeof(Company));
                ((SecurityStrategy)securityStrategy).AnonymousAllowedTypes.Add(typeof(Employee));
            };
        })
        // ...
