System.Web.Security Namespace

.NET Framework version 2.0

Defines the delegate for the GetRoles event of the RoleManagerModule class.

[ VB ]
Public Delegate Sub RoleManagerEventHandler ( _
   sender As Object, _
   e As RoleManagerEventArgs _
)

[ C# ]
Public delegate void RoleManagerEventHandler (
   object sender,
   RoleManagerEventArgs e
);

[ C++ ]
Public __gc __delegate void RoleManagerEventHandler (
   Object* sender,
   RoleManagerEventArgs* e
);

In [ JScript ], you can use the delegates in the .NET Framework, but you cannot define your own.

The declaration of your event handler must have the same parameters as the RoleManagerEventHandler delegate declaration.

sender

The RoleManagerModule that raised the GetRoles event.

e

A RoleManagerEventArgs object that contains the event data.

The RoleManagerEventHandler delegate is defined for the GetRoles event of the RoleManagerModule class.

You can handle the GetRoles event of the RoleManagerModule class in the Global.asax file for your ASP.NET application as shown in the example for this topic.

You can use the RoleManagerEventHandler to replace the creation of the RolePrincipal object by the RoleManagerModule with your own custom object. To do this, define a delegate using the RoleManagerEventHandler and assign it to the GetRoles event of the RoleManagerModule.

The following example shows the GetRoles event included in the Global.asax file for an ASP.NET application. The GetRoles event adds a trace notification for an application where trace is enabled in the Web.config file.

public void RoleManager_OnGetRoles ( object sender, RoleManagerEventArgs args ) {
   args.Context.Trace.Write ( "Roles", "Applying Role Information" );
}

Public Sub RoleManager_OnGetRoles ( sender As Object, args As RoleManagerEventArgs )
   args.Context.Trace.Write ( "Roles", "Applying Role Information" )
End Sub
