RoleService.SelectingProvider Event
.NET Framework (current version)
Occurs when a RoleService instance determines which role provider to use for checking the user's roles.
Assembly: System.Web.Extensions (in System.Web.Extensions.dll)
The RoleService class raises the SelectingProvider event when it determines which role provider to use in order to retrieve the user's roles. You can create an event handler for the SelectingProvider event to select at run time which role provider to use.
The following example shows how to bind an event handler to the SelectingProvider event in the Global.asax file. The event handler determines at run time which role provider to use, based on the user name.
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
