The following example shows an event handler for the SelectingProvider event. The event handler uses the SelectingProviderEventArgs object to check the user name and to set the role provider to use. The event handler is bound to the SelectingProvider event in the Application_Start
method of the Global.asax file.
void Application_Start(object sender, EventArgs e)
{
System.Web.ApplicationServices.RoleService.SelectingProvider +=
new EventHandler<System.Web.ApplicationServices.SelectingProviderEventArgs>(RoleService_SelectingProvider);
}
void RoleService_SelectingProvider
(object sender, System.Web.ApplicationServices.SelectingProviderEventArgs e)
{
if (e.User.Identity.Name.IndexOf("@example.com") > 0)
{
e.ProviderName = "EmployeeRoleProvider";
}
else
{
e.ProviderName = "CustomerRoleProvider";
}
}
Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
AddHandler System.Web.ApplicationServices.RoleService.SelectingProvider, _
AddressOf Me.RoleService_SelectingProvider
End Sub
Sub RoleService_SelectingProvider _
(ByVal sender As Object, _
ByVal e As System.Web.ApplicationServices.SelectingProviderEventArgs)
If (e.User.Identity.Name.IndexOf("@example.com") > 0) Then
e.ProviderName = "EmployeeRoleProvider"
Else
e.ProviderName = "CustomerRoleProvider"
End If
End Sub
The SelectingProviderEventArgs class supplies values to the SelectingProvider event handler. You create a SelectingProvider event handler to select the role provider at run time.
The RoleService class raises the SelectingProvider event when either the IsCurrentUserInRole method or the GetRolesForCurrentUser method of the RoleService class is called.
You use the User property to retrieve information about the logged-in user. To retrieve role information through a non-default role provider, set the ProviderName property to the name of the role provider that you want the RoleService object to use.
