Examples

The following example shows an event handler for the SelectingProvider event. The event handler uses the SelectingProviderEventArgs object to check the user name and 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

Remarks

You use the User property to retrieve information about the user during the SelectingProvider event.
