Handle Logged In Event

Sitefinity - On Premise – Configurations & Setup

Afternoon all,

I'm new to the 4.1 model of Sitefinity. I would like to override (or handle) an event that fires after a user has logged into Sitefinity. I need to fire some environment specific code that shoves some information into session state.

I could handle this in my membership provider, but I was trying to find a way to isolate this code outside my provider (for reasons of portability in the near future).

Thanks everybody!
Joel

Hi Joel,

There aren't global events that are thrown when a user tries to log in or it gets log out. For the time being I think that you should handle this in your provider.

All the best,

Thanks Ivan!

Sadly, my vendor has built all of their code on top of user controls and obfuscated their code. So I need a page lifecycle in order to properly instanciate their classes.

I've built my own login user control to get around the issue, but I'd like to know: can I add to the existing sitefinity login page? I seem to remember finding the existing codebase in 3.7, but I didn't know if that held thru to 4.1.

If I cannot modify (or add some code) to the existing Sitefinity login page, can I direct all logins to my login page? (I believe that I have tried setting it in the web.config's membership section to no avail, but I'm more than willing to try again).

Thank you sir!
Joel

Hi Joel,

I suppose that you want to modify the backend login control. There are two options

1. Map the external template and subscriber for Authenticate event directly in the ascx

You can simply map the templates for LoginForm and LogoutForm in the backend by going to Administration->Settings->Advanced->Controls>ViewMap->Create new and fill in the fields accordingly(all without the quotes):
for LoginForm:
HostType: Telerik.Sitefinity.Security.Web.UI.LoginForm
LayoutTemplatePath: "relative path to your custom LoginForm.ascx where you have specified the custom paths to the ChangePassword and ForgotPassword pages"

for LogoutForm:
HostType: Telerik.Sitefinity.Security.Web.UI.LogoutForm
LayoutTemplatePath: "relative path to your custom LogoutForm.ascx where you have specified the custom path to the ChangePassword page"


default templates

2. Replace the LoginForm - this is the backend control. It is added through ObjectFactory so you can use Ioc to replace the LoginRouteHandler with a custom one. You need to inject a custom handler inside RegisterRoutes method of Telerik.Sitefinity.Abstractions.Bootstraper

routes.Add("LoginUtil", new Route("Sitefinity/Login/View", new LoginRouteHandlerCustom()));

In LoginRouteHandlerCustom you should override InitializeHttpHandler and add your custom LoginControl.

If the first option works for you this would be the easiest solution. The second one is quite complicated.
