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.
[code]....
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.

I am using default asp.login control similar to this (inside a LoginView)
[Code]....
I am adding a default text to both of the text field (usrname and password) when the page first load (C#).
[Code]....
I am just wondering how can I retreive the Textboxes (user name and password) to that I can clear the default text on focus.
All I need is how I can get the reference of the text boxes inside a javascript function .

I have a fairly simple form:
[code]....
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:

I tried to get the LoginName control inside LoginView LoggedIn template , despite several methods, the code still could not work.
I wished to change the default username to the customer name.
Here is the code:
<asp:LoginView ID="LoginView1" runat="server">
<LoggedInTemplate>
Hello, <asp:LoginName ID="LoginName1" runat="server"></asp:LoginName>
<br />
<div style="text-align: right; margin-right: 5px ">
<asp:LoginStatus ID="LoginStatus1" runat="server" LogoutPageUrl="~/Home.aspx" Font-Underline="True" />
</div></div>
</LoggedInTemplate>
</asp:LoginView>
At the code behind :
protected void Login1_LoggedIn(object sender, EventArgs e) {
LoginName loginName = LoginView1.FindControl("LoginName1") as LoginName;
Response.Write(loginName.ToString()); //for now I used Response.Write for testing purposes
}

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.

But I'm getting this error:
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object. Can anyone tell me why I'm getting this error? And what is the right way of accessing those controls from code behind which are placed inside a loginView's RoleGroup?

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.

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.

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?

I want to know how can I display role-specific markup using loginview?
I have these three roles, Admin, Editor, Moderator
Each and every user will belog to only one of the following role groups
1. Admin, Editor, Moderator (Some user/s will have all these three roles)
2. Admin, Editor (Some user/s will have all these two roles)
3. Admin, Moderator (Some user/s will have all these two roles)
4. Editor, Moderator (Some user/s will have all these two roles)
5. Admin (Some user/s will have all only this role)
6. Editor (Some user/s will have all only this role)
7. Moderator (Some user/s will have all only this role)
Now I want to display some links that will be specific for each role group to which one or more users will belong. So the links I want to display for these role groups are following
1. Admin, Editor, Moderator => Only Links of all the pages of Admin, Editor and Moderator
2. Admin, Editor => Only Links of all the pages of Admin and Editor
3. Admin, Moderator => Only Links of all the pages of Admin and Moderator
4. Editor, Moderator => Only Links of all the pages of Editor and Moderator
5. Admin => Only Links of all the pages of Admin
6. Editor => Only Links of all the pages of Editor
7. Moderator => Only Links of all the pages of Moderator
I have tried doing this using RoleGroups in Loginview but couldn't succed.
Can anybody let me know the correct way of going this?

In my Membership.aspx, I added a LoginView control. Then on the LoggedInTemplate, I typed "You are Logged in. Welcome," and a LoginName control. After testing from ASP.NET Development server and IIS server, now my LoggedInTemplate showed "You are Logged in. Welcome," several times before displayed only one LoginName/UserName. Why? Something wrong when testing in the ASP.NET Development environment or IIS server configuration?

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");
commentsLoginView.DataBind();
commentsLoginView.RenderControl(htmlTextWriter);
}
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.";
container.Controls.Add(label);
break;
case "LoggedInTemplate":
label.Text = "YOU ARE LOGGED IN.";
container.Controls.Add(label);
break;
}
}
}

I'm in the process of trying to figure out how to program in ASP.Net.
My senario is this:
(A) I've created a master Page
(B) In The master page I have a Login Control that is contained in a LoginView control.
I cannot figure out how to get the events to fire when it's in this sitution.
If the Login control is situated on it's own the events (LogginIn etc) will fire?

I have a LoginView control that contains a PasswordRecovery control. Upon page_load I don't want this to be visible. When the user clicks a hyperlink button ("forgot password?" type of button), then it'll be made visible.
But I'm having a hard time making the password recovery control invisible at runtime. Here is my page_load function:
[Code]....
It is the only password recovery control in the LoginView control, so I don't understand why this isn't working. The password recovery control is still visible when the page loads in my browser.
