Custom Login control

Looking for some assitance on a custom login control, which will provide redirection to a url based on a custom property, for now I have just set this to google to test the control,

I have created a class inheriting from the LoginWidget

    public class Login : LoginWidget

    
        protected override void InitializeControls(Telerik.Sitefinity.Web.UI.GenericContainer container)
        
            base.InitializeControls(container);
            this.DestinationPageUrl = "www.google.com";
        
    

I have then registered this class via the admin->settings->advanced->toolboxes->pagecontrols->sections, see attached screenshot

I have then created a dummy page to test the control but when I preview the control I get the below error, any help would be greatly appreciated.

Hi,

We have not encountered the problem before. In version 5.4 you can easily authenticate the user with SecurityManager.AuthenticateUser(); and one of the available overload. This will enable you to create an entirely custom Login Control to best fit your scenario.

Can you post an example I have tried various attempts at a custom login control with no luck.

Thanks

Hi,

 Here is a simple custom login control example.

Thanks al, good stuff!!

In my case, I'm try to extend the default login and add two-factor authentication for all member to login the e-commerce portal, could anyone provide the advice here? 

Many Thanks!!!
