Security :: Create Login Control With DropDown List For Username?

Feb 18, 2011

I have an ASP.Net application that uses the Membership Login Control. The thing is, we wanted to avoid giving our members more than they need to worry about, so we didn't want to have to make each a custom username. So the thing is, I want to make the Login Control display a DropDown List populated with a list of usernames as opposed to a text box.

Security :: Login Control Requires Email / No Validation Set Anywhere For The Email?

Dec 7, 2010

I am using the Login control to create a new user. I have it where if the user adds and email address, then this automatically popuplates the username textbox with the email address. I want it where if they don't have an email address then the user can just create their own username instead.

But what happens is if they create a username, but the leave the email blank, a defined error message appears saying that an email must be provided. In the login control properties I have set the property
RequireEmail to False but the message is still appearing.

Can anyone help me find out why the email is always required? I do have custom validators for other parts of the login, but have no validation set anywhere for the email.

Security :: Secured Site Using The Login Control / Do Not Want Them Redirected Based On Their Login Status?

Mar 24, 2011

I am doing a simple secured site using the login control. I would like users to be redirected to their dashboard page once they log in, but after that if they choose to browse I do NOT want them redirected based on their login status. I am using the generic template provided in VWD with the basic login setup in the template including the tabbed ASP menu control - nothing fancy, nothing custom. This is intended to be something very simple and quick. Here is the code I am using for the page load...


So if I do this code WITHOUT the "IsPostBack", logged in users are always redirected to their dashboard and cannot see the hompage. However with that IsPostBack test, the redirect after initial login doesn't work.

I know this is extremely basic and simple, but I am restarting with this stuff after a year away, and I need a nudge.
