Security :: LoginView Control: Programmatically Created, Doesn't Switch From Anonymoustemplate To Loggedintem?

Mar 30, 2010

I'm creating a LoginView in a class file rather than at design time.

The equivalent LoginView created in a .aspx page and used the same way works fine, and User.Identity.IsAuthenticated is switching from false to true once I log in as a user so the problem must not be there.

But even once logged in, the programmatic version of this LoginView is not switching from the Anonymous template to the LoggedIn and the output is always "You are not logged in".

Anyone have ideas? thanks.

here is my code to create the loginview

private void BuildAddCommentView(HtmlTextWriter htmlTextWriter)
LoginView commentsLoginView = new LoginView();

commentsLoginView.AnonymousTemplate = new LoginViewTemplate("AnonymousTemplate");
commentsLoginView.LoggedInTemplate = new LoginViewTemplate("LoggedInTemplate");



here's the LoginViewTemplate class

class LoginViewTemplate:ITemplate
string _templateType;

public LoginViewTemplate(String templateType)
_templateType = templateType;

public void InstantiateIn(Control container)

Label label = new Label();

switch (_templateType)
case "AnonymousTemplate":
label.Text = "You are not logged in.";
case "LoggedInTemplate":
label.Text = "YOU ARE LOGGED IN.";

Security :: Login Control Inside A LoginView Control?

May 17, 2010

I have a image CAPTCHA script (downloaded from the web) that I am placing inside a Login control. I have also place that Login control inside the annonymous template of a LoginView control.

When I try to do the image verification the text box to verify keeps coming up Null and gives me an " NullReferenceException: Object reference not set to an instance of an object" error.

I have the same control working inside the CreateUserWizard control so I am not sure what's wrong.


I have tried variations for the LoginView1.FindControl("txtVerify"); but this is the only one I have been able to use with Intellisense that does not cause a build error.

LoginView Inside FormView Control Is Not Databinding On PostBack?

Apr 20, 2010

I have a fairly simple form:


However, once the update is finished (and I call e.Cancel = true), the LoginView control does not databind its children... so they are all blank. The FormView's viewstate is still fine, as all the rest of the controls outside of the LoginView appear fine. I even handle the FormView_DataBound event and a Trace shows that the FormView is being databound on postback.

Why then is the LoginView not keeping its ViewState/being databound? Here's a sample code snippet showing the flow:

LoginStatus Inside LoginView Doesn't Trigger LoggingOut Event?

Aug 11, 2010

I have a LoginView in my APS.NET application with AnonymousTemplate and LoggedInTemplate. I've put LoginStatus control inside LoggedInTemplate but it doesn't work as expected.

Here's the code

<asp:LoginView ID="LoginView1" runat="server">
<asp:Login ID="Login1" runat="server" OnAuthenticate="Login1_Authenticate"
DisplayRememberMe="False" PasswordRecoveryUrl="/"
You are logged in as
<asp:LoginName ID="LoginName1" runat="Server"></asp:LoginName>.
<asp:LoginStatus ID="LoginStatus1" runat="server" LogoutAction="Redirect"
LogoutPageUrl="/" onloggingout="LoginStatus1_LoggingOut" />

All event handlers are correctly defined in code behind file.

The problem is that if user logs in he will see his user name with logout link from LoginStatus control. Clicking the logout link takes the user back to login form (both login and logout form are part of the same user control) but if I refresh the page the user is still logged in.

I've noticed that if I move LoginStatus control outside the LoginView then logout process works as expected. I've also noticed that when LoginStatus is inside LoginView then it doesn't raise a loggingout event.

LoginName loginName = LoginView1.FindControl("LoginName1") as LoginName;
Response.Write(loginName.ToString()); //for now I used Response.Write for testing purposes

Security :: LoginView, Sign Up, Customization?

Apr 18, 2010

What is the easiest way to manipulate the built in LoginView and membership handlers so that users of a website can sign up with just their email (entered twice) and a password (entered twice)? The default is asking the user for a username, the email (just once) and the password (twice). How can this be tweaked, including adjusting the in-built aspnetUser table in the database?

Security :: Equivalent For LoginView Based On Roles?

Apr 21, 2010

I have a website where users can login and they have different roles/privileges. I want to have it where the user's view of the webpage is determined by their role. Right now I am storing the role in the UserData property of the FormsAuthenticationTicket class (which is retrieved from a database during login). When the main page is loading, I want it to check the user's role and then only show the controls/portions of the page that are for that role. For example, if the user is not an administrator, they shouldn't be able to click on a button to delete a record. At the moment I am using labels to hide or show areas depending on the user's role. Something like this:



And here is a portion of the markup code with the Labels:


This works, but doesn't seem to be a very good way to handle this type of thing. Is there a cleaner, more elegant way of doing this? Something similar to the LoginView control, but which I can use for roles?

Security :: LoginView Control / Can't See The Pages And Data?

Oct 14, 2010

Now that some of the Security matrix has been approved and site is somewhat more functional. We are going back thru adding the loginview to the pages that need it so we can control who can adn can't see the pages and data.

To keep it simple, here is what i have setup.. Because if this setup, i cant access my controls and the page wont display either template. Now even though the aspx code below is a very stripped down version of what i have, the code behind has references to controls that dont show in my example, but they are there in my actual page. I Just removed alot of information to make the post more clear.

Security :: Get Username Based On Loginview Control?

Jan 6, 2011

This may be very simple but I can not figure it out. I am using ASP.Net 3.5/Visual Studio 2010. I have placed a LoginName Control on the page and the login name is properly displaying. I am using forms Authentication and it is set up properly in the web config file. I simply want to insert the logged in username value into the database table so I can track who created the records. I am happy to be able to insert the UserID value. I assume the values are derived out of the aspnet_Users table. Hopefully someone can provide a way to do either. I am not a coder so giving me a quick try this answer won't help me much. I would need to really see the entire solution and code.

Security :: Loginview Control To Manage Membership?

I am using loginview control to manage membership loggled in data and anonymous data. But since I have to copy entire data to login view template. I think it is not perfect solution in case i just have few differences in all type of templates. I tried to use loginview whenever I actually need it. But it supports just after form declaration.

Also what if I need to have multiple loginviews. Is there any way to do this manually. I just dont like to copy entire design for each template and just like to manage identical changes.

Security :: Adding A Loginview Control To A Page?

Jul 18, 2010

I have a page that originally didn't contain a login view. I have now added one of those so that I can vary the display according to role membership.

However I have some VB code that references ojects that were originally on the main page but now sit within the Loginview. These code segments were triggered on a Page_Load event. Since moving the objects on the page all of the references to objects there now fail as if they didn't exist. (Presumably because they are now within a LoginView)

I assume I need to change the location of my code but am stuck to find out where it should now go.

I assuem now I need two versions of my code too - one to match each of the two role possibilities for the LoginView?

When the page is first loaded, the hyperlinks are displayed correctly. however, after editing a record and saving the changes, the 'View Results' column loses the hyperlink.

I tried creating a temp hyperlink column outside a loginview control and this seems to work correctly.
